| MARK IV Switching Marix
I have one on the bench and I need the switching matrix or something. Also is the schematic floating around correct? Any help would be appreciated. |

Gregg, Are you looking for a block diagram switching matrix or a matrix schematic...some Mesa service packages have block diagrams, some don't. Also, are you working on a IV"A" or a IV"B"? Not sure what the differences are because, although I've worked on several Mark IV's, they belong to cusomers that bring them in from time to time for retube or whatever and they all seem the same to me. There probably are subtle differences (or maybe not so subtle)...the Mark IV isn't known for it's subtleties :-0

I'm looking for a matrix schematic something similar to the one in DR or Tremoverb. I'm trying to figure out when the LDRs are on or off. Actually below each one is written when it's on /I guess/ except for RY1 and RY2 which are relays I suppose. I would appreciate a schematic though. Also the power supply section schematic is missing.

Sorry, I didn't get it. I think there's a 10MB message limit. Maybe you should try spliting it with WinRar or something.
