Photo of my Music Angel XD-800MKIII Tube Amp. The is Version C from Feb 2012 and has all Lampitzer mods (lampizator.eu), plus more. Customized by Lyle of Lone Wolf Tube Amps professional in San Diego. Lyle removed all negative feedback, improved connections and checked all caps, etc. He verified that all Lampitzer mods were already done. He created a full schematic of my tube amp (Ver C) - only one available to my knowledge (only up to VerB on internet). I have PDF copy for anyone interested in schematic of Version C for my Tube Amp.

All tubes rolled up from stock.

Presently using the following set of tubes:
4 Gold Lion KT88s, 2 JJ ECC81's, and 2 Telefunken ECC85s
KT88's matched and biased to 37Ma each.

Tube sounds fabulous in my system. No feedback nor hum (completely black background even with volume to max)....

Have some videos on Youtube under my name john4sd of my tube amp system
if anyone is interested. Difficult to capture actual sound of my system on Youtube but I did some sample videos with my Zoom Q3HD recorder in the highest audio I could record. Enjoy.

Comments welcome - John :)
