In Reply to: RE: What capacitors to buy to refurbish old RCA amp? posted by maxhifi on February 09, 2016 at 16:58:34
If you are going to have a long term relationship with this amp I suggest you step up to some Solen or similar caps to replace the 'lytics. They perform way better than any electo cap. The original oil caps in the power supply will last forever if they have not been abused. The problem I don't like with the russky caps are that their leads are quite short. So, if your original caps need to span any distance they might not be able to reach. good soldering! dak

Long term relationship? I would definitely owe them some major alimony if I decided to move on.. I've had other amplifiers in and out of my system but prefer the sound and power of the RCAs.
I like the idea of solens or similar in place of electrolytics, if I did that it would mean the amplifier has no electrolytic capacitors at all.. that can't possibly be a bad thing.
The price difference is not that great. Also the size of the Solens are compact except for the large capacitance units. If your B+ is less than 500v, Panasonic makes the DC link which are rated at 500v. They come in rectangular packages. You can fit your own leads so that is a little more effort but that would allow you to use different types and gauges. They seem to have less of a break in period since they sound good right from the first note. cheers, Dak
