Nice work. I am pretty sure there is a schematic on this forum somewhere for grabbing the extra voltage.

I am pretty sure it can't be done without swapping out the transformer. While I was researching changing my 20/20 I remember reading that the 20/20 is one of the few Mesa Boogie products with a multi-tap transformer. Not 100% sure, but 99%. Check with a tech. www.tubeampdoctor.com will probably...

Heu Joe, good stuff in this thread... http://forum.grailtone.com/viewtopic.php?f=13&t=37721&start=15

Yes I AM happy!!! I'm not very familiar with the MkV, but I have no doubt the Axe would work very well with it. I think and important thing with effects placement is having them at the right point in the signal chain, before or after the pre-amp. I had originally tried the 4 cable method with...

I've bought an AxeFX, mentioned it in this post viewtopic.php?f=5&t=39778 and have been asked the following: "Would you mind starting a string under effects on your FX unit honeymoon progress or send me an email? I just got a MKV and love the preamp it has but want great effects, comp, chorus...

Yep, still need a power amp. Or a full range flat response speaker (FRFR), like a PA speaker. I am using a powered one, so my rig is now simply guitar>AxeFx>PA speaker. So light and easy and stress-free! The AxeFx produces a whole signal chain all the way through to sims of cabs. I initially...

OK I swapped the fan out and also tried a lower air flow fan. Turns out the original is the best. But now I've bought an AxeFX anyway. (Fantastic BTW). It too has a fan....

Hmmm. I see why - you switch capacitance to infinite. My mod switches it to zero. It still sounds better but I should have looked at the circuit diagram more closely. I see it is the 1uF cap and bridging this also shorts the tube to ground. I feel a bit stupid. Fortunately I have mostly left the...

Hi Steph, The picture links are not working.

Hey, I think I'll try that. I guess you have installed a relay circuit and hooked up to a footswitch? I've gone really simple and just put a switch in parallel with each of the caps, and mounted them in a little plastic box on top of the amp. My pre-amp is shallow, so I have the room to do that...

Thanks Snoopy. Turns out the conversion is fine. I might have a power tube on the way out, but hammered it for hours on Friday with no issues. Getting new tube set just in case. BTW I did the deep mode and made it switchable. Not sure whether I like it better with/without, but I can switch one...

I was using a "slo-blo" fuse initially when it first blew, and for the next time I didn't have one handy so used a regular 1A fuse. I have some more slow blow fuses now, so planning to change it back. I don't have an ammeter to put in line, but do have an AC current clamp. I think I can borrow...

No problem at volume on other channel. Assume therefore not on the power supply side.

OK, so if I understand right - same fuse type and just play with the volume at a low level. I'll do that tomorrow and report back. Thanks

I've bought a used 20/20 and the I also find the fan pretty noisy Part of it is mechanical noise form an old fan but a lot of it is the airflow itself. So I've ordered a replacement Sunon fan of the same rpm and airflow and another which is about 2dB noisier from the fan itself, but about 20%...
