Title: Rhodes Peterson preamp problem
Post by: kidbill on February 26, 2019, 03:12:47 PM
Hi!
I got a problem with my peterson, when I active the vibrato
it makes some noise like a heartbeat (at the rate of the vibrato) all the time
I wonder if it could be a ground problem?
Preamp is fully recapped so no problem with the caps.
Many thanks!
