I put a pair of Tung Sol reissues in the MT200.. and WoW!! Nice warm tone! :thumb-up:

Now, on the Mesa 50/50 I was reading that V2 and V3 are both phase inverters :facepalm:. V1 splits the signal to each side. Can someone confirm this? MJMP? SC? rnolan? Anyone?

Correct! Is that the old 50/50 or the new one?

Well that's an interesting way to do it, so V1 is the buffer tube for both channels (one triode each) and V2 and V3 are the PIs, one per channel to drive the output tubes (which I assume there are 2 per channel in push/pull)

Mesa 20/20 Deep Mod:
http://forum.grailtone.com/viewtopic.php?f=5&t=31723

Thanks for the link SC. I've got the deep mod on the 20/20, it was done by the previous owner ... I have no idea what the 20/20 sounds like as standard, but consensus of opinion seems to favour the modded version.

I'll try some different tubes for the PI positions, probably the 12AX7LPS that you've mentioned previously. If it doesn't work out for me I'll try the 12AT7, I can reuse the 12AX7LPS and install them in my SP-77 (I seem to remember Soldano recommending the Sovteks).

MJMP, under-biased power tubes are a concern ... it wouldn't surprise me if they were, I think perhaps it's a Mesa tube strategy. It's a little frustrating that the bias is not easily adjustable (trimpots, etc), so I'd be really out of my comfort zone.

I don´t have the schematics of the 20/20 DynaWatt, but there´s a 33k resistor in the fixed bias circuit... Replace that with a 15k resistor and a weber WP503L 50k bias pot in series  :thumb-up:
