I’m repairing a Yamaha PG-1 guitar pre-amp and am in need of a reverb tank
The model # I have is 1BB3C1B
1 – Type 1
B – Input Impedance 150 Ohm
B – Output Impedance 2,250 Ohm
3 – decayLong (2.75 to 4.0s)
C – Input Insulated/Output Grounded
1 – No Lock
B – Horizontal Open Side Down
The spring had come apart inside and the other spring must have broken in the past and was removed.
let me know if you have something similar!
