Tape Delay Project

3 Nov

Since I’m in LA and my Truck is sleeping in Georgia, I needed something to keep me busy.

I bought 3 old Marantz PMD-222 pro Tape decks, that were sold as not working/junk.

The plan is to build a analog tape delay effect. Ive got the tape decks working (so I have 2 spare now) and I figured out how to control the tape speed in both play and record modes. Ive also built a mixer circuit on some vero board

 

But… It didn’t work.

Im not really sure what was going on, I’m got an audio signal to the tape but no mixed signal output, Im guessing there is a mistake in my circuit. Do I cut the red wire? or blue?

I’ve given up with this approach and have etched some pcbs on copper boards… stay tuned.

    Have you tried turning it off & then back on?
