Hi all, im having an issue with ghost notes. When playing high notes the amp creates another tone lower and sounds dissonant.
Ive tried different speakers, guitars, new sets of tubes, changing lead dress, different bias, raising pcb, placing sheilds between transformers, chopsticking components with no change.
The strange notes/harmonics are present when plugging into the pre-amp return so this would mean its an issue with the power section?
Ive also increased capacitance in the power supply thinking i may have ripple. ive gone through and checked all values and wiring. ive also built several amps before this one with no issues so i doubt its a soldering issue(could be wrong though).
I see one other member has the same issue as me in the frugal amps post if that means anything. Any help would be greatly appreciated.
Hi Caley, were you able to solve the fly back voltage problem of the other post?
