Possibly, but it may have acted in concert with the attenuator. The attenuator has variable impedance, so with an 8 ohm load on a 16 ohm output possibly. I didn't set up a mismatch obviously but who knows. Honestly attenuating this amp sounds worse than just running a pedal through the FX loop...

The proof...is in the pudding I need to sit down

Now to find out why...

I did a full retube and out the stock OT back in, still no dice. Input and speaker outs have continuity...At the end of my abilities here. The thing is fully lit, fuses intact... minus sound. I wonder what other component it could be?

Did replacing the fuse fix the issue? I'm having the same issue however all fuses have continuity. Strange enough, my F3 is 250v...Wondering if I'm having OT issues...however the speaker will register a pop when switching power modes. Thanks

Unfortunately there is no sound with the power cable plugged in, cab hooked up and guitar plugged in only. I even tried bridging the loop for the hell of it. Whats weird is there is no sound at all coming from the speaker, like even cranked on Red with the gain all the way up, no hiss or...

I'll see if I can get anything out of the loop, worst case scenario I have the stock OT. Just a bummer if it is the case (New OT Sounds amazing, but only 2 years old), plus I'm wondering if my attenuator has anything to do with this, hopefully not. I'll wait for a full retube until surgery...

Howdy, So this MT15 fully powers on, all tubes lit, bias voltage readings are good. The cables have been checked, when switching the half power switch you can hear it in the speaker, the connection is active. I have tried multiple good sets of power tubes, no dice. I have swapped preamp tubes...

6 solder points. You could technically splice the existing wires if you don't solder. I had to drill one hole in the Chassis for a mounting screw, I used the other existing hole.

"We do have a two screw mount that sounds amazing with EL34’s and is 4K rated to 50 watts. FBFVO-40-M $143 3 ½” mounting hole centers." - Mercury Magnetics If this is helpful, the rep from the company was quick in his responses "...but be aware, just swapping the OT will not make it a 50 watt...

Plug and play after a quick bias. Put EL34L's in mine and love it. Multimeter and a jewelers philips is all you need. BTW just enough clearance in the chassis for the tubes.

What output transformer did you go with? I just put EL34's in mine and would love to do this conversion next.

This will mirror a lot of previously stated, although I'm assuming this is a 2 channel amp Master volume. Resonance and presence power section options. 2 loops, channel assignable/combinable) Fixed tube bias like Mesa's with a 6L6/EL34 switch (yeah right) Variable power section attenuator...

I found this thin batting with a waxy material on both sides and covered the inside of the cabinet after sealing with silicone and expanding foaming the metal handle recesses. The rear access panel is also weather stripped in super tight as well as the baffle for the front mounted speakers. I...
