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.
