Product:
Transformer - Fender®, Reverb, for Pro Reverb

Question:
Hello. Can you tell it's input and output impedance? Thanks.

Answer:
Fender does not provide specs for it's original replacement parts as they are intended strictly as replacements. However, the Pro Reverb uses a 4AB3C1B tank which runs at an impedance of 8ohm in and 2250ohm out so this may shed some light on it's specs.
