Rogue Cronus Magnum Dies Help


I was listening to my Rogue Cronus Magnum this afternoon This unit had cap and resistor upgrades done at Rogue by the original owner a couple of years ago., Today suddenly the remote stopped working I changed batteries which were fine I also tried to program a LT 350 but that did not work either I called Rogue but they had no idea. 20 minutes later the volume control started working via remote.

I went for 20 minute walk with the dog. Upon arrival home I found the amp the amp dark No tubes lit , no blue light on. I tried the power button on and off Nothing Unplugged it waited then plugged it in Nothing I checked the power supply fuse and it is fine I checked another large fuse inside. it is fine as are the 4 small ones. Push the power button It does nothing Took it in the kitchen Same thing Dead as a whatever. What happened here?? The main transformer go out??? Thanks

last year i traded in my rogue cronus magnum "dos" that i had for almost three years of faithful service.
the dealer i went to was playing a system fronted by a $3K Rega Elicit R amp driving a pair of klipsch la scala speakers. the music sounded very good and enjoyable. pleasant.
the dealer connected up the cronus (stock tubes) to the la scalas and the sound became instantly much more open, clear, transparent and BIG.  amazing !  the cronus mag absolutely shredded the rega elicit R, with stock tubes to boot !
i ran some reasonable NOS small signal tubes in the CM II and the sound was worlds better than the stock tubes.
three power amps and three pre amps later the sound is finally much improved over the cronus mag- but the journey was difficult and expensive.
sometimes you don’t know what you’ve got till it’s gone.
Glad to hear you figured out the problem.  BTW, I also wonder why people would post unhelpful replies but that seems to be the way of some. Reminds me of someone I once knew who would get angry if asked for advice and then that advice wasn't followed.  I'm asking for advice, not asking you to make the decision for me.
The winner is...rodman9999   Bridge rectifier was out  Total cost $330Now I just wonder how this unit would compare to a Marantz PM 14s1?
Kind of like a dog with a bone? What is your deal?? Let it go.

all I was simply saying that if it only costs you a small amount of money and you like this unit, then its worth it.
it might just be a $5-10 part that went bad and it will take the tech a few minutes to diagnosis it...but what you can you do ?     .         
  if you are going to sit here and complain about how much something costs to ship or the cost of a  $5-10 part that went bad , but they charge you some crazy amount for diagnosis / parts and labor....then maybe you need to find a different hobby.       and that is all you have done is complain on how much its going to cost.   deal with it and move on.

 do you think that you are the only member here that has had to deal with something like this ?             

have a nice day .
Kind of like a dog with a bone?  What is your deal??  Let it go.

I do not take a car to the dealer  I change my own oil. If a bearing goes bad I fix it. If the vacuum cleaner cord needs replacing I do it. If a outlet  is bad I fix it.  If a speaker terminal is bad I replace it  If a tonearm needs rewiring I do it.  (Not good on the eyes for blind guy)   Point being if I can do it I try to.  Sending something and wasting $160 in shipping is a last resort  ONLY if  I cannot do it or have it done locally.  Why is that such a hard concept to understand?? 

Here is very realistic scenario  and I am almost betting on this kind of thing  They get  10 minutes into the bench check  find out it is a bad cap or something like that   A $5 to $10 part  They remove it and install the new one .  I have done this and it takes maybe 15 minutes  Cost including shipping  Around $360OR
I figure it out or someone says ya that happened to me Here is what I found  $10 cap and 20 minutes of my time DONE
AGAIN why is making an attempt to avoid the hassle and cost of sending it across the country and paying someone 3 digit bench fee  so hard for you to understand?  LET IT GO
It is in their hands now.
so you spend the $350 or so to get it fixed.....but if you like the unit and it hasnt given you any trouble since you have had it, its worth spending the money to get it fixed.

nobody likes when equipment goes down, but its all part of it....and its no different than spending money on our vehicle and we have to take it to the dealership...but we dont complain about that....its part of owning a vehicle.

the unit will be like brand new when it returns.....
 You are correct bacobits.  Update  It is is on the way.  Proving my point that costs could quickly  get out of hand  Just to ship it one way even with my account  is $83 (normally $93)  It will be slightly less then that coming back say $75  Bench check $175 plus parts for a simply repair anything major and up it goes. Point being for a simply repair (if I am lucky)  minimum of  $350 of which over half is shipping back and forth. Hence the reason I wanted to try and figure it out.  Well at least the experts have it now
Well it IS a huge amp. 60+ lbs shipping weight. and very uneven weight $75 one way. Because of the transformers in the back and its weight in the carton. Original packing is a must , drop it your screwed! Carton must be labeled "HEAVY" on the outside.They send a new replacement carton back. Do not send Power tubes.
I know, and had mine upgraded a few years ago to " MAG II" status. So understood, I didn’t like doing that and I’m in NC not that far from PA.Luckily all went well. and never ever use UPS!!!!!!!!!!! Rogue turns around pretty fast especially now with business being slower. They had mine 2 days and back travel another 2. totlal tosend  in, 2 to fix ,2 to return my state. Total 6 days.
Good luck!

My cables are $100 used interconnects (old AQ and Analysis Plus. Speakers are $400 to $700 used Mirage OM5s, M3s and Infinity RS 2.5s
if you can afford all of that , then you can surely afford to ship the Rogue......as that will be nothing to what you have spent on cables and speakers.

i sent you a pm when you first posted this and suggested that you ship it back to Rogue.....other members have chimed in and said the same thing.....so I dont see why you dont just do it.?

if it was a huge amp then I could see where shipping costs could be a factor and the risk of it being damaged in shipping.....but this amp doesnt weigh all that much......and it doesnt have to travel very far, so not many hands will handle it.




I think you are on the right path. You brought up the common stuff, fuses etc. After a quick look, it seems like a factory repair issue. 
 First I want to say  thanks to those that tried to help.
I too am often amazed at responses that get sent on various sites hence I avoid posting much.  Most members try to be helpful  as most on this post have  Then there are other responses that just assume things and are not helpful.   " members will spend pretty much any amount on equipment , cables, speakers,"  Who are you talking about??  Really?? My cables are $100 used interconnects (old AQ and Analysis Plus. Speakers are $400 to $700 used Mirage OM5s, M3s and Infinity RS 2.5s   I did not see a poll on whether something should be posted or not  did I miss it??   FYI  I ship many things and know pretty exactly what it costs and how long it takes.  Nice job riley

I guess the logic of trying to avoid the cost, expense and time as well as possible damage to the item by shipping  and just hoping  someone might have had this experience and it is a simple fix is just to way out there.  Again thanks to those who thoughtfully responded  it will go Rogue
Even with my FedEx or UPS account it is still $50 to $65 to ship this thing each way and going back and forth is 8 days total just shipping time. Once there the meter starts running plus parts pretty sure their rates are high.

amazes me that members will spend pretty much any amount on equipment , cables, speakers, etc....but when it comes time to ship the unit as it needs to be repaired, they complain how much it will cost.   
Then you are worried about the back and forth time....which it might not even take that long.
if you want the unit fixed, then send it to Rogue and be done with it.

I wouldnt have even started this thread, I would have contacted Rogue, got the info I need to ship it and it would be on its way.     
Rogue does not charge outrageous price to repair unit.  I wouldn’t screw around with it, I would ship it to Rogue. 
Thanks  I little tight in there and with my eyes it might be harder
rodman, Read my post  The timeline is there.  The remote issue (not working and then working)  happened a couple of hours before it died
You mentioned being able to get the remote working ("I came down 30 minutes later and tried and all of a sudden the remote worked. Very odd.").       If the Cronus was completely, "dead": how do you know the remote was working?      Just curious, as that's how you’ve characterized the unit.
Since you own a multimeter: check the voltages at the bridge rectifier.     (no AC in = transformer / no DC out = rectifier)      Don’t take anything for granted, regarding the power switch, solder joints (etc), ahead of the tranny.                 If those voltages are good, follow the circuit/voltage, until you find it’s stopping point (CAREFULLY).
Ok boys lets play nice.  As an FYI  I worked in the audio bizz back in the day  and trained folks in sales and product   I am not a tech but can do basic repairs.  The reason for posting this is in the hopes someone else had this happen and it was simple ie replace transformer or cap. I checked the fuses for continuity .  As for the power switch I thought about that but keep in mind this was sitting there playing and when I cam back it was dead.
Obviously sending it to Rogue is on the list but here is the rub  Even with my FedEx or UPS account it is still $50 to $65 to ship this thing each way and going back and forth is 8 days total just shipping time.  Once there the meter starts running plus parts  pretty sure their rates are high. Point being if I can do it myself or local I need to try.
A couple of strange things . Two hours before this happened the remote stopped working the volume control. I tried to program another remote and it did not work either. I tied everything ,angles distance unplugging the unit and letting it sit for a minute and so on.  I  then called Rogue.  I want to point out I got this 6 months ago used and the guy had sent it into Rogue 3 years ago and spent $400 on a cap and resistor up grade. I have owned it for 5 months. and have talked to Rogue twice with basic questions and it was nice. When I called Friday I did not really feel the love which I will address with them . Did you you change the batteries?? Seriously??? They had no answer but I really felt it was the unit itself  I cam down 30 minutes later and tried and all of a sudden the remote worked.  Very odd.  The unit did have a lsight transformer hum on the shelf but many amps do that.   I did notice a little more noise, /hiss/whoosh form the speakers the last few days but I was also using a different preamp tube and thought it was that. The again caps sometimes  make a whoosh sound right before they go bad.  Point of all this if I cannot get someone who has had this happen to explain then she goes to Rogue. Thanks

I checked the power supply fuse and it is fine I checked another large fuse inside. it is fine as are the 4 small ones. Push the power button It does nothing
Check the power switch contacts.
And you have been doing this how long as it's not always apparent or obvious without a meter or magnifying glass. 
Did you actually test the fuses with a meter or did they just "look fine"?
