In Reply to: RE: If your amps are working,Leave them alone. posted by Michael Samra on August 06, 2016 at 20:56:36
Michael
Thank you for that answer of wisdom and truth. Since you have a wealth of knowledge ,
and I am starting in the hobby, the question is: would you change the capacitors, since the amp is fairly old, and those might need to be changed? If so, what capacitors would you recommend? Or would you leave it alone and look at upgrading amplifier?Thoughts?
Thank you kindly.

Nichicon also has a gold series and Philips has the BC series which I really like.The caps I would change would be the main power supply input filter caps..There,you would be a little more creative and use a more exotic type cap there as well as in the power supply sources.These amps already use Schottky diodes but I need to look at the schematic again to see what are the best caps to use and where.

Mike what do you think about these in the signal positions.
I've been using these on my SS amps in signal path positions. Wonderful clean clear sound. None of the old lytic sound we all knew and hated. Very natural sounding.
I love those caps..I use them as cathode bypass and as couplers in SS amps.

20 or so year old power supply electrolytic caps. are legitimate candidates for replacement. Panasonic and Nichicon are go to brands for those kind of parts. Look for combined low ESR and 105 o C. specifications. A high ripple current rating is good too.
Don't buy off "EBone". Get the genuine article from Mouser.
