Power Tubes were out for the photo. When I played it it was flipped over..

:D I'm always amazed at how much stuff Boogie can stuff into a tiny box and not have lots of noise.


I was going to change my DC-3 to Cathode Bias today, but I can't figure out where to put the extra 10 watt resistors. Just no room. It does sound freaking amazing though.
 
Great porn and a very nice cabinet. I have always been impressesd how Mesa stuffs the guts and keeps the circuits quiet. Honestly, wait until you see some Road King guts. It's dizzying.

How about some shots of that cab.

No kidding! I'd now love to see a Mk. IV short chassis! My IIc's circuit doesn't look nearly as massve.

It the same circuit, but add an independent R2, 2 tone stacks, 19 LDR's and a switching matrix and your set. Also, remove three filter caps.

That thing is a sweet rig. You Woodie gave me a, no I wont go that far.

When you say "remove three filter caps", could you provide more details on the location of these caps on the Mark IV (model A) schematic and what is their effect on the tone of the amp.

Thanks
