I have this in another thread but anyone who can try and date this amp I would appreciate it. It is a conversion that someone took either a Brownface or Blond Bandmaster Head and had a Brownish Pink 3x10 cab made with Jensen reissue speakers. It looks like they put a Bassman Transformer in it to get the right output for the 3 8 Ohm speakers. I just took it apart and the inside looks like maybe a 61 with all the Astron caps. Also I guess someone put the rectifier 5U4g in it and there is also a pot with a trimmer next to it. Maybe Bias? Any and all info is appreciated. I love this amp!
