Rogue 88 problems

Pren,
Regarding Marakanetz's post, do yourself a favor and try the simple procedures I recommended before you despair. Oxidation and debris build-up have nothing to do with design or build quality. If that doesn't work I would contact Mark O'Brian at Rogue. Mark and his staff are extremely helpful and very responsive. FYI I have used my 88 Magnum and a Rogue 66 Magnum preamp almost daily for over three years without any issues other than the aforementioned which were easily rectified.

Well I can tell you that I spent about 1 month trying to get rid of the arc issue. I tried everything from switching out tubes to moving my components around. I finaly took the approach of cleaning up the mess of power wires in the rear. I made an effort to isolate every power cable and make sure they were all quite a distance from each other. Problem gone. I was giving up but it worked. The sound is better now also. I have since ordered a naw power cord.
I have no problem with my fan. I can only hear it if I get right down next to it.
I have had mine for 9 months and for the first time last night I put it in UL mode. Definate difference in sound. A little lean for my taste but it is there. Maybe because I have been listening it triode mode for 9 months that now I prefer that sound. Sometimes if you haven't spent time with the sound and you switch back and fourth you might not catch the difference right away. Give it some time in one mode or the other.
Next, don't listen to this guy about reliability. He appears to be one of these wannabe experts that needs to spread his opinion around. You have a very good amp, and there is not another builder around that is as nice a guy and as helpful as Mark at Rogue.

Scottht makes a good point. Cleaning the tube sockets did not eliminate the arcing right away but it did stop sometime thereafter so that may have had nothing to do with the problem. After reading Scottht's post however it did occur to me that at the time of the arcing I was using a fairly high-end power cord that was somewhat inflexible and didn't seem to connect as securely as the stock cord. I believe it may have been after going back to stock power cord that I no longer noticed the arcing.

My information comes from not once heard complains about performance(not meaning a sound) of Rogue amps and preamps. I've never looked inside these units but I can assume that they're using high bias circuitry that makes a tube life short so freequent retubing may be neccessary.

I happen to see that in listening room with magnum M120 having a same described hiss and noise.

I guess that some models are built good and some of them aren't.

I'd perform overall look onto the solder joints but after one year it realy shouldn't be an issue in any electronic device.

The performance, reliability and responsiveness of Rogue Audio is well documented in this and other forums across the internet. Let the reputation they've earned speak for them.

The internet is a big place and bad news travels fast. If their were reliability issues , you would have heard of them by now.

I've never had reliability issues with my Rogue stuff and I've always had emails answered promptly when I asked questions. Many companies do not treat their customer like this and we have to give fair praise to the few that do.

Email Rogue.
