Which model Boogie is this?

[drewl]

1x12 combo with reverb, the fancy wood and cane front.
Two 6L6, 5-12AX7, on two separate boards.
Similar to a MKI or II with no EQ.
clean channel and overdrive channel with lead gain, lead master, tmb, reverb and presence on rear, loop jacks hidden under chassis, all stuffed in a little cabinet.


None of the schems. I find quite match up.

No hard fault, just lacks "singing overdrive" from lead channel according to owner.

One coupling resistor "looks" to maybe have been changed to mellow it a bit.
You know when they use a 3.3M with like A 10pf in parallel between stages, the pf is gone.

Is there anything written on the end of the chassis in marker? Mesa offered the cane front cabinet in several models.

[drewl]

SR 46 written in marker on both sides of the chassis.

No other indications of a model number.

Judging by the PC boards and parts it's an older unit, not a reissue.

What is on the end means something, but I do not recall the code.

This may help:

Somewher I had a list or which controls had pull switches on which Mark series models.

Right, it has the same layout as a MKII A or B, but those schematics don't match.

I'll do some more searching, just thought I'd ask here.
Thanks.
