Hello, I'm new on the forum, but I read a lot of the great posts and I want to thank you all for the tips and tricks!
Now I want to replace the two filter caps, C32 and C33, 100uF 450v. Does anybody has some experience with the JJ ANH 1005011? http://www.jj-electronic.com/pdf/ANH.pdf
Do I need to replace more caps?
Thanks

Or this ft cap: http://www.ftcap.de/downloads/elektrolyt /datenblaetter_2010/A2010.pdf much longer lifetime. Does somebody have experience with these caps?
Thanks

Haven't used either but JJ And FT both have good products, I think the FT's are a little overpriced but they may be cheaper where YOU are. I would replace EVERY electrolytic in that amp as they are now over 30 yrs old and can dry out. One shorts out, you could loose a transformer. Make SURE that you replace the ones on the driver board and if it HAS a bias board, those too.

I'd change ALL the blue ones as well as the ones in the "house". Those little ones don't cost much and they can cause a lot of grief. Don't know what brand those are but they kind of LOOK like panasonics but THEY usually have their name on them. They're probably job built for MM back in the day.
