I have a 1979 Club and Country 100 watt combo. Similar to JCM800 series. I would like to recap it.
What are the best filter caps? Considering JJ, LCR, F&T. Would you be able to "hear" a difference between these brands?

I think he is asking about electrolitics, which I don't think sozo makes. Please excuse me if I am wrong.

Yes the filter caps are electrolytic capacitors, very important part in your amp, but thatīs often not realized. Many thoughts about transformers, PTP, circuit caps, tubes etc. but if your filtercaps are old and dried out your amp canīt sound good, and for sure you can hear the difference clearly, the better the quality of the cap, the more better the sound.
My favorite caps (and not only the filter caps) are this:

not cheap, but great.
here is a nice overview:

all electrolyic caps have +/- 20% tolerance
i have a 10w SE high octane preamp type amp with the same filter capacity as my plexi ...... i don't hear a difference in tone
caps are part of the scheme to reduce the AC ripple in the RC filter circuit on the B+

Anybody use any of these? I noticed the new Hendrix amp uses these, as well as Germinio:

ARS is an electronics wholesaler in Van Nuys, CA. These may just be relabeled cap cans made by Mallory, LCR, Sprague, etc. I doubt they make their own stuff.

No relabelled LCR, F&T or JJ, because the ARS's are slightly thinner in diameter compared to the LCR aso. and sometimes can't be tightened properly in the original metal clamps.

I am using them now too. Im pretty happy with them. Ive had good luck with them, and also with the f&t's. Im not sure who makes the ARS caps, but they are smaller diameter than the jj, and f&t. Ive never had any issues with them not tightening up in a clamp though.

Very good inforamtion guys on the ARS. I was fishing for comments because I am about to buy some caps and was looking at the different options. Thanks

Thatīs not correct, -for example- Mundorf electrolytic amp caps have a tolerance of -10/+30 and also in other points they are improved, the average microamp current leakage is only: 150 microamp than 200 or more at the F&T and others, parasitic capacitances can affect the sound with noise and feedback, depending on the amp you will note it.
They have the diameter of the old DALY`s, three solder lugs, and fits in every American or British amp with the clamp mounting.
The only bad thing is , they are not the low cost replacement like some ebay noname products, but they are one of the best electolytics you can get, and you can find a lot of information about them in the www.

Changing the power supply filter caps is absolutely necessary if your amp is more than 10 years old; 5 years old if you play professionally
:oI got a good chuckle out of that.

I know the quality of electrolitics make a big difference in hi-end tube audio, but can you really hear a difference in guitar amps between Sprague and Mundorf? If so, I will have to get some of those. The price is not too high, unlike the Blackgates.
