Re: New Caps for amp power supply
I honestly do not know, they are 40 years old and out of production. The markings have been worn away but i did read something about SRS caps, that they were made by a company called SRS.Leave a comment:

Re: New Caps for amp power supply
Thanks. I found samwha hc caps 10kuf for £4 over here in britain, vishay pht-sr series for £20 and nippon smh for £33.
Does it make an audible difference to spend money on expensive caps, and do you have any suggestions for suitable caps, what are your favourites for 10kuf 80 volts are there any you tried and enjoyed.
The stock caps are 50 x 80mm (D X H) but unfortunatly are out of production so i cannot replace with like for like.Leave a comment:

Re: New Caps for amp power supply
Thanks for the replies, much appreciated.
If esr is unimportant, should i choose a cap with the max ripple current spec, is that important?
Also, should the big 10kuf cap be bypassed by a few smaller ones, something like 10kuf+1kuf+100uf, will help in any way.Leave a comment:

Re: New Caps for amp power supply
The amplifier is a quad 405, and the caps are about 40 years old and bulging, because of this i have been worried to turn the amp on.
Yes i could use epcos as they are a good manufacturer just i have been given some advice and would love your thoughts on it.Leave a comment:

New Caps for amp power supply
Hi And thanks for reading this post. I am going to replace the stock 10kuf caps in the power supply of an amplifier and have been told it is better to parallel a few smaller caps rather than using one large cap. Apparently one big 10kuf cap is slow to charge and discharge and gives a slow kind of sound. Tried googling this point but cannot find it anywhere. Do you think it could be true.
Also I was going to purchase low esr caps but have been told that this will not make a difference with the 50hz mains ac, that low esr caps only make a difference at high frequencies such as smps

Hi Guys. I am richard, 21 years old, young naive and a beginner. The questions i will be asking are going to be of a simple nature and will probably be laughed at and not taken seriously, but at the risk of humiliation i will try putting up a few questions.Leave a comment:

Re: Any recent feedback for Samwha caps?
Samwha are made by samsung and are usually okay.
You didn't say what the voltage rating and capacitance of the stock caps are.Leave a comment:
