Dating mesa boogie amps
Get some NOS tubes to find out what all the fuss was about back in 1977, when everybody playing fusion had to have one.
Hey all you amp slutz out there- Trying to find out some info about this old Boogie combo I acquired recently.
Looks to be pretty well used, and has been re-capped and re-tubed. All punch tape labels on the back, there is one above the "speakers" label next to the speaker plug that has "A1207" on it. Also the bottom of the head has green writing indicating what tubes go in what socket, along with the pictured circled letters RIS or RLS and what must be a date 8-77.
Mic has graciously granted permission to post the stuff on the JT30 page on the off chance that it might be useful in the context of Blues Harmonica.
Mic is not responsible for the content, just the collection. * Hinged plastic carrying handles on AC4 & AC10, large leather strap on AC15.
I know A's have two sends and two returns that are laid out in a "square," and B's have three jacks laid out in a triangle.
The tone controls work differently than I'm used to on any other amp, the treble control really makes a huge difference in the sound, and where it sits seems to affect the other EQ controls, especially bass. The pull bright (or pull boost-can't remember) seems to defeat the tone controls- Would anyone know if this is correct? The tone knobs have more influence over preamp distortion than in other amps.I would call Boogie: 707-778-6565 They are only open Monday-Thursday though.
