I also have a v1 200, a 100, and had rented a 300 (what a beast!) for about 4 months.
100% agree with you irt the tone settings and keeping the mids pretty high. I usually have the mids set somewhere around 8 to 10 depending on how where the range and scoop are set.
I think that all 3 have a similar tone stack. To me, the range control is what is called the frequency control on the 100 & 300. The 100 & 300's fixed deep switch replaces the 200's variable scoop control & the fixed resonance switch replaces the 200's variable resonance control. My EQ settings on the 100 & 200 are almost identical.
Like many, I had originally fallen into the mid scoop trap. With most of my previous amps, setting the mids that high would've made them sound too brassy or nasally. Not so with these. There's a very noticeable reduction in volume starting at any mid setting under 6½-7.
Seeing how your 200 has 6550s (what did you mean by "upgraded"?), I thought I'd recheck mine. As I thought, it has JJ KT88s but what I didn't see before was that they're from The Tube Store as they have their logo/sticker on the bases. They must be well matched as the amp is very quiet with zero hum.
By chance, have you tried using EL34s in your 100? I'm curious about that but haven't heard one using them yet.
Nice knobs on your 200. Are they older Traynor knobs?
I like the Traynor cabs too. Used to have a TC1510 but I sold it & the first 200 I had during a rough stretch. I have a really nice condition TC810 but now I'm considering getting the TC210 & TC115 Neo as I saw a pair on sale for a decent price last weekend and would definitely be enough speaker for the rooms I play. Currently, I usually run the 200 through an Eden Nemesis 212 when playing out. Folks around here basically have a bird at the sight of an 810 plus the 212 only weighs about 36 lbs.
Do you notice any tonal differences between the 1510 and the paired 210 & 115?
