Description

For sale this vintage soviet
analog tape
delay\reverb\echo effects processor "
TESLA STUDIOECHO-A
". The unit was produced in 1980s by well-known "Tesla Radio Plant" in Czech Republic, Eastern Europe. It was one of the best, reliable, compact & high-quality tape echoes produced in the soviet block.
You can switch the motor on and off with a special button, so the tape is preserved. For a tape loops you can use the standard audio tape - Ampex, BASF etc. New tape loop installed.
This unit has one issue - some low hum on 3rd recording head. Especially with added bass EQ
.  I don't think it is a big problem as it is almost inaudible when played, but still for your consideration.
I don't know how to fix it and have no time to repair in service. This issue can be heard in the end of attached youtube video from exactly this unit.
