Capacitor log Mundorf Silver in Oil


I wished I could find a log with information on caps. I have found many saying tremendous improvement etc. but not a detailed account of what the changes have been. I have had the same speakers for many years so am very familiar with them. (25+ years) The speakers are a set of Klipsch Lascala's. They have Alnico magnets in the mids and ceramic woofers and tweeters. The front end is Linn LP12 and Linn pre amp and amp. The speaker wire is 12 gauge and new wire.

I LOVE these speakers around 1 year ago they started to sound like garbage. As many have said they are VERY sensitive to the components before them. They are also showing what I think is the effect of worn out caps.

There are many out here on these boards I know of that are using the Klipsch (heritage) with cheaper Japanese electronics because the speakers are cheap! (for what they can do) One thing I would recommend is give these speakers the best quality musical sources you can afford. There is a LOT to get out of these speakers. My other speakers are Linn speakers at around 4k new with Linn tri-wire (I think about 1k for that) and the Klipsch DESTROY them in my mind. If you like "live feel" there is nothing like them. In fact it shocks me how little speakers have improved in 30 years (or 60 years in the Khorns instance)

In fact I question Linn's theory (that they have proved many times) that the source is the most important in the Hi-Fi chain. Linn's theory is top notch source with lessor rest of gear including speakers trumps expensive speakers with lessor source. I think is right if all things are equal but Klipsch heritage are NOT equal! They make a sound and feel that most either LOVE or hate. (I am in the LOVE camp and other speakers are boring to me)

So here goes and I hope this helps guys looking at caps in the future. Keep in mind Klipsch (heritage Khorns Belle's and Lascala's especially) are likely to show the effects of crossover changes more then most.

1 The caps are 30 years old and
2 the speakers being horn driven make changes 10x times more apparent.

Someone once told me find speakers and components you like THEN start to tweak if needed. Don't tweak something you not in love with. Makes sense to me.

So sound
Record is Let it Be (Beatles)
The voices are hard almost sounds like a worn out stylus.
Treble is very hard. I Me Mine has hard sounding guitars. Symbals sound awful. Everything has a digital vs. analog comparison x50! Paul's voice not as bad as John's and George's. Voices will crack.

different lp
Trumpets sound awful. Tambourine terrible. Bass is not great seems shy (compared to normal) but the bad caps draw soooooo much attention to the broken up mid range and hard highs that are not bright if anything it seems the highs are not working up to snuff. I have went many times to speaker to make sure tweeters are even working.

All in all they sound like crap except these Klipsch have such fantastic dynamics that even when not right they are exciting!

Makes me wonder about the people who do not like them if they are hearing worn out caps and cheap electronics? Then I can see why they do not like them! If I did not know better from 25+ years of ownership that would make sense.

For the new crossover I have chosen Mundorf Silver in Oil from what I have read and can afford. I want a warm not overly detailed sound as Klipsch already has lots of detail and does not need to be "livened up" they need lush smooth sounding caps. Hope I have made the right choice?

When the crossover is in I will do a initial impression on same lp's. Right now it goes from really bad (on what may be worn vinyl) to not as bad but NOT great on great vinyl. (I know the quality of the vinyl because tested on other speakers Linn)

The new caps are Mundorf Silver in Oil and new copper foil inductors are coming. I will at the same time be rewiring the speakers to 12 guage from the lamp cord that PWK put in. PWK was a master at getting very good sound often with crap by today's standards components.

The choice of speakers would be a toss up now depending on what I am listening to. Klipsch vastly more dynamic but if the breaking up of the sound becomes to much to effect enjoyment the Linn would be a better choice on that Lp. If I could I would switch a button back and forth between speakers depending on song and how bad the break-up sound was bothering me.

Only the Jupiter Copper Foil. In my pic it has around 30 caps replaced. I did not put in the pic power supply and electrolytic caps.

I know it would seem with old Fisher I am going for vintage sound but I was not. 

I just used old Fishers as they were pretty cheap then... Was not going to cut up old McIntosh's or Marantz amps.

That being said Steve Hoffman has mentioned how good these old Fishers sound stock. With all new Duelund caps they are not even in the same league. MILES better! Steve Hoffman has McIntosh and Marantz as well and worth $16k.

Eric I started with natural tone and then by changing caps increased the dynamics by a HUGE amount. Like going from antique to modern. 

They do NOT sound old. Sometimes the new caps are 30x as big in volume. MUCH more dynamic.

I do not think many will spend close to $1k in caps in an old amp but it is the best $1k I have spent!
I hope this thread gets going again on who has paper bobbin output trannies?


My guess is 15 or more feet of paper in the transformer. That could be 15 ft of plastic. I can not imagine how that can be good!
I have spent quite a bit of time on our tube loving guitar amp brothers pages and magazines. 

Here is an amp builder talking about different transformers.

I have all the parts for a complete internal speaker rewire with Duelund. 

After reading Jeff Day's site I am going to have to get some Duelund IC's which will be virtually my last plastic!

My second system was bought for back up parts really in case anything went in main system and in the beginning I did not listen to it much. That has changed A LOT! 

In original part of thread I had one vintage amp redone. (Duleund where room Jupiter in tight fit) In second amp I threw the hodgepodge of caps in Duelund, Jupiter and VCap Cuft and Jensen and it sounds AWESOME even though my tech guy does not like it. He would like to see all the same caps in a circuit. Of course he would never redo an amp and put in a hodgepodge of caps, what would the customer think?

Almost nervous to put in the Duelund last two caps in amp and tweeter caps (sitting here) plus Duelund internal wiring as it will send the speakers off or better the main system! 

Not sure which I am more nervous of setting things backward or having the second system best the first? Then trying to figure out why?!
