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 :)

Hello. I bought a MA xd800mklll mod.C and it came yesterday from China. Have not tested it yet, i want to upgrade it first. Have planed to do the Lampizator,( change the four caps, and short the resistors ),way of upgrade.
I would love to have a copy of your schematic drawings, of the MA.
It would help me a lot, i have nearly no experience with work inside amps. But Lampizator has a nice guide, so i hope to make it work out.
I like your youtube videos of your HiFi gear. They sound very nice on my PC gear.(stax headset,gustard dac).
Hope to hear from you, have a nice day, from Yngve, in Norway.

Hi John,
I own one of these and am currently trying to upgrade it from stock. The schematic online is obviously not my version, and in addition, the PCB's are marked with components that are not the ones installed!
I would be very appreciative if you would send me a copy of your schematic. My email is craigsires@gmail.com
Thanks in advance for any help you may be able to provide.
Craig
