Hello,
I bought three non-working stereos on ebay for $9.00 each two Pioneer's (450 and a 780) and a Sansui 5050. I've gotten the 450 and 780 working again and I had a question about the 780.
As part of getting it up and working I had to replace the 8000uf capacitor pair as they were dead. I used caps with a similar value (8000uf 50v). When playing the stereo the bass is good however the highs are a little flat. I was wondering if there are any suggestions on ways I can improve the range a bit.
Besides the two large capacitors I replaced 11 transistors. The three large transistors with heatsinks on the left, the six transistors in the protection circuit in the middle, and the two Darlingtons on the bottom. The Darlingtons were replaced with 80's instead of the stock 50's.
Any advice would be appreciated. Thanks!
