Just a few PSU caps and perhaps some 4.7R resistors on the power rails. The power transformer is the main thing. Be careful how you wire it up, I think it will be a fairly annoying job.
Ray - you can't go wrong although I seem to have acquired a lot of new noise. I will re-route a power wire and see if it goes. I think in a quick dem the tx sound will lose every time, even to the HDAMs as it's much more subtle and less vibrant. But it is so much purer and less aggressive. My girlfriend and I both clearly preferred it playing Judith Owen (very well recorded jazz/folk) as the active stage was very in your face by comparison and less natural.

Have you tried different connections??
i.e. parallel / serial on either primary or secondary

Nope, just parallel/parallel, as that seemed to be the recommended way to go. I'd not want to change the gain to be honest. Interestingly, though, it sounds much quieter than through the op-amps and HDAM. That could be a lack of distortion as much as anything but I've not measured...
Slightly off-topic but has anyone had a chance to hear the new caps Brent is offering on his site for modding? I am somewhere around level 3 and these are on my list for the next level.
SI's making caps for you now? WOW! Will they blow up soon after fitting!
* I feel I know Simon well enough now to join in with this type on banter.
**I in no way suggest that any work or components supplied by Brent are of inferior quality.
There thats my *rse covered i think! 😀
LOL
It would be nice if they were named after Simon. I could have called them noobkaps.
Only joking Simon 😉

P.S 13 days is very good 😀

well I knew Brent would say they were brilliant! just testing to see if he was awake...so no one knows besides the meister? I can hardly believe I'm the only one who knew about this. Google is your friend.
I just ordered some Mundorf HV M-Lytics for my tubeamp, i'm pretty confident they will sound fine 😀
F&T is one of my favorites too. I'm not surprised they make the caps for Mundorf 😎

Those caps sound excellent in a tubeamp. What's the value and ESR of those you've ordered?

I use a C-L-C filter with a 32+32uF (2.5mohm) and a 100+100uF (0.8mohm), and behind that a 50+50uF (1.6mohm) for the driver and preamp stage. All are the radial HV types.
<STRIKE>I think you have a typo on your website, 22 ohm is a bit high 😀</STRIKE>
EDIT: ESR is measured at 100Hz with these, but a few mohm is low, could they really be that low??? I just copied the numbers from the Mundorf datasheet... Your's look more feasable Brent.
