I know it’s an old thread but this was the reply I got from Mesa boogie when I inquired about having a Mark V crunch channel mid pot modded to a Mark V25 mid pot. “We do not make modifications such as you request. Also, there is a different circuit involved when comparing the Mark V:25 and...

What effect does it have? Reduced gain? Any demos?

emailed Mesa Garey Noble (MESA/Boogie) Aug 8, 14:35 PDT Although its not printed in the tube task chart, V2A is the 3rd gain stage for CH2.

In the Mark V 25 which tube is used for stage 3 on ch2? The tube task chart in the manual doesn’t say.

Has anyone done this mod? I’m curious as to how it sounds Any demos?

Just curious why their is no nomad sub forum?

It's normal for the bass to seem muddy or flubby with Mark series amps. I usually keep the bass below 9 o'clock on mine. The tonestack in the Mark series comes after the first gain stage (pre distortion). When you increase the bass you are feeding a bassier signal INTO the distortion which has...

Huh that's exactly why I didn't buy the one I tried in store. The stores might want to make sure the demo models are "broken in".

Finished it today. I changed out the 3 resistors between the B and C voltage. I swapped out the 5watt 1k5 and left a little space under the pcb. The old one was charred on one side from a previously burned screen resistor. I replaced all the screen resistors and wired them to the choke the cap...

Never mind. It appears to be the same as the mark 3 which I found a schematic for

Anyone know how the 60/100 watt switch works on the DC10 and how it's connected? Or have a schematic for it? Thanks in advance

So i opened it up today and their appears to be a burnt 1k resistor. If u look at the schematic I t's the 1k from C. It also seems that the pcb has been repaired at some point. I'll have to order that resistor any other issues I should look for? I have replaced all the tubes so if one was bad...

I'm having an issue with my dc10 combo. After playing for a few minutes the bass seems to intermittently fade out then back in. And occasionally the highs will do the same. I've noticed this on the lead channel by not the rhythm. I play mostly on the lead channel. While this is happening I've...
