Toshiba Amplifier Repairs
Toshiba SB-620 Stereo Integrated Amplifier
Vintage Toshiba amplifier from 1977 was making a pulsing noise through the loudspeakers with various noises it shouldn't be producing. I found several dry joints here and there. Looking at the capacitors on the PSU board, I made an executive decision to replace them all, sounded okay afterwards.
