This week I had the opportunity to have a close look at a Fender Twin Reverb amplifier.
This guitar amplifier has been equipped with four 6L6 tubes.

At this moment, the amplifier has three anomalies and is being repaired now : One 6L6 has turned white, most likely due to the loss of vacuum, one magnetotransformer of the reverb unit has a broken wire and a 10k potentiometer has a damaged shaft.
