Thanks John. I replaced all electros upto 3.3uF on an AU217 (taking care of voltage and available space) and there is a noticeable audio improvement.
However, since the 217 is just one model above BOTL, I'll avoid any "over description" of the audio improvement.
Cheers,
Robert.
Hi, a big thanks is in order for posting about this receiver, as I just recently bought a 661 and plan on eventually recapping it. and I am really curious about doing the above, replacing all electros up to 4.7uF with film caps.
did you even replaced them in the power supply? or just caps in the signal path ?
thanks,
