I have an HD 130 Reverb head (2275-130) I'm trying to date. I took the chassis out and all of the pots are dated late 7941 (41st wk of 79) or 8006 (6th wk of 1980). From what I've read this model was made from 1974-79, but could be I have an end of production build. Serial number is B011669. From the high serial number and pot dating I think this one would be a 1980.

The driver board is the one in the LAST pic with the two large heat sinks that are black. there SHOULD be a number/letter combo like db-2 or something like that. MIGHT be on the bottom. Don't remember. Mike.
