Marshall 2061x issues??

Send it to Marshall directly. Get it fixed under warranty for free. It sounds like a problem they have been having with the output transformer.

 

My output tranny has been replaced twice.
All of my feelings about this have been detailed
in this thread at the Plexi Palace

Its a drag, but the amp still sounds so good,
darnit all to heck.

I hate amp techs who BS me with crap like
"it was a loose solder joint" and then you bring
it home and it does the same thing.....
Did you ask for a refund on the first repair?
Was it an authorized Marshall repair center?
If possible I would try another amp tech.

My 2 tranny's were replaced under warrenty,
no cost to me. If the third one blows I'm going
to see about a replacement / refund. Which
is a shame, because the amp sounds awesome.

 

Zero problems w/ mine also. 5yr parts and labor, I'm not worried. BTW, I even use a THD Hotplate on 1 click.

 

Marshall is running those EL84s at a very high voltage, when I took a reading on mine I was surprised. I've been hearing reports of failures because of this. The big amp makers are usually more conservative with this kind of thing. Myself, I prefer the tone or EL84s being run at these higher voltages in my homebrews, but to save tube life I use higher value screen resistors, approx. 2.2K, this settles things down a bit without loosing the tone advantage of running the EL84s at 390volts. I intend to do this with my 2061X whenever I can get around to it.

 

I just got one this Monday. I noticed a strange distortion like noise also a couple of days ago. Today I thought it might be a speaker problem, so I plugged my Rt66 in to the cab, and no noise. I'm just going to return it though, that's to much $$ to be tied up in an amp that I have to worry about.

 

ducmike...since you are getting rid of your Marshall, allow me to suggest looking into a TopHat Club Royal combo. It is the greatest amp that I have ever played!

Mr. PlexiBreath, is this 2.2K resistor you speak of safe to put in my 2061X? I'd love to "settle things down a bit without loosing the tone advantage of running the EL84's at 390volts."

Also, what wattage? 1/2w or higher?

 

I love the idea of one of the 20-watters. I'm one of the people that is waiting to buy one until they fix the transformer issue. There have been so many reports of problems that I would think Marshall will have to fix the issue.

 

I know a local guy here that had his 2061 go down on him during a gig.
He was absolutely livid.:BITCH

He was thankfull he had a crate powerblock that got him through.:AOK

 

I've had mine for 10 months with no issues running it hard, but I am in need of a new set of powertubes. What a great amp.

 

No issues so far. :AOK
Great amp. I got mine used about two weeks ago so it has traveled across the USA a couple of times. It gets turned up regularly and sounds great. I haven't measured the plates on mine yet but I will, maybe adding the screen resistors as suggested.

 

I had a 2061X for a year and ran it HARD pretty much all the time. Gigged, practiced, and recorded with it. Other than replacing the tubes in October, I never had any problems or issues with it. Certainly no failures with the transformers.

I can't say for sure, but I've been messing with these amps for the last few years and haven't had or heard of a problem. That would be a real bummer on a piece of vintage gear. They're some sweet little amps for sure.
