I think the term is: Winner, winner, chicken-dinner!
Hmmm, I also have a 465B that looks to have been in barn.... possibly serving as a door stop. I have BD139's assurance they are nice to work on, which is a relief, as I feel that mine will also need lots of working on. Total, like, kwinky-dinks! I even have a broken knob (fnar, fnar) due to poor shipping on the 2465B I've got, it even bent the shaft of the "intensity" pot, and all I found of the knob were about 60% of the crumbs.
The "var" knob I ordered from Greece arrived here today, ordered about three days ago, colour me amazed.
