Add myself.

I just had the same issue. I sent it back to Mesa they did the fix/mod and mailed back in about a week. Awesome!

Thank you my friend! I will search out a amp tech or send back to MB.

Thx. I have no lights on front of amp also. May have to send in to boogie.

Hello, Mark V 90w combo amp. I noticed yesterday my fan stopped working cooling the tubes. Watched video on fan replacement. I ordered a fan. This morning removed the fan in question and tested with a 9v battery. Fan was working fine? Need help to troubleshoot why my fan stopped getting...

Remove your cell phone out of the room. I chased a click in my amp and it ended up being interphence with my cell phone causing a clicking. Crazy!

I have noticed that 8 of the MB 6L6GC tube I own measure in the high 20s ma. That seams cold for 6L6s. Correct me if I am wrong. I just ordered 2 matched sets of JJ @ 44ma which should be 70% of my amp. Stock.

What year MarkV do you own that disappointing you?

Thank you for the info. I have a Eurotube single socket probe which I was able to find the PV. This amp is running 475v @70% approx. 44ma shooting for. I will be rolling tubes till I find a match set. this amp is 2009. Then I will test amp #2 to see if the ma matches amp #1 which is early 2001...

How can I measure the plate voltage with out taking the PC board off inside that covers the tubes?

I'll go thru them when I get a minute. They are not all MB tubes.

Thx. I have lots of vintage tubes. While rolling them I notice they range from 62ma-20ma. Why are the ranges so wide? One tube stronger than the other?

How did you make out on this? What should my ma be on this amp? Right now I have a matched set at 30ma? Is this considered cold? Thx

I am looking for the original that came with amp. 18 1/2'x 9"

Yes. I also have one. I cracked by accident resiliently. I have 2 combos. (1) I bought used few years ago. No card.

Will do. Let me know also. I bought mine in 2009 or close to that. The 2nd I bought couple years later used and did not come with one.

Looking to buy (2) Settings cards that came with the Mark V amps. Boogie said they do not have any. Thx.

Mark V recommended settings card/chart placed on top of amps Does anyone have this to sell? Thx. ATR1

Here is what Mesa sent me when I was struggling with Channel #3. I also use a KOKO BOOST to kick it in the ass.. "My recommendation would be to work on dialing a tone starting with more channel master (& less overall output should volume be an issue). I tend to run the channel masters on gain...

That is a very nice clean rig. I need to check out the FX8. I really have no knowledge of them or what they can do. I'm interested in how the signal can be routed. Is there more than one output that the effects can be routed to. Like I can tell there is a stereo output but is there another...
