RE: technics SL 1200 power supply "upgrade" = snake oil?

You're right I didn't look close enough and it's also weird that I had forgotten about our conversations.

Though the ripple is not zero. And you correctly point out rectifier impedance will cause ripple after thge rectifier to be a bit higher than it is before the rectifier. If I'm not mistaken your screen shots are measurements before the rectifier?

KAB also has a post rectifier regulator as part of the upgrades they offer. Apparently the idea is to add both the power supply and regulator if you want the full on treatment.

I was a little unsure if any of your screenshots were taken post rectifier, ie right at the rail where the motor draws power. Did you look at ripple after the rectifier?
