My questions :
1) Filter caps swapped with newer versions by bad workmanship. Incorrect values too. I ripped them off. At least , old can caps stayed on the amp so i can see the original values . One 50+50 uf can cap and two pair of 20+20.
2) The right lug of the intensity pot was on Filter cap i found. Is that right place to be ? Or ground? I drew as it is going to ground here.
3) Is there any right place to be for that Blue cable which is going to speaker socket lug ?
4) Is there any similar amp design to follow?
5) Please tell me if you see any error there.
Thank you everybody for your precious time.
