I built one heathkit power supply kit before attempting this kit, and i'm fairly good at soldering.
I ordered the 12ax7 phono stage with the power supply. When it arrived the package was busted inside and all the components are scattered inside the box, the transformer mount was bent, and one of the tubes they sent me was the wrong brand of tube. The PCB was completely different from the one in the picture, the parts list was for an "updated" version of the kit supposedly. They emailed me the new schematic and parts list. I made inventory of what i had(which was extremely difficult), and i was still missing a lot of components from the new parts list/schematic. They tried to help me for a few weeks, they sent me some new components, but they can't really help me because they're chinese. I actually finished soldering the amplifier section together, but then realizing that the transformer i got isn't even the right output and the power supply kit was also missing parts. I emailed them and let them know that i needed a different transformer, and that i lost faith in the product and that i wanted to return the kit. I've haven't had a response back on that for months. I've attached some pictures i could find.
reasons not to buy:
instructions are the worst
schematics + parts lists are obsolete for what they give to you.
you may receive the wrong parts
i only suggest buying from analogmetric if you have expert knowledge with electronics, and you have your own supply of components for when they forget to send stuff.

AM's PSU HV400 is a big nightmare.
I have 2 of them since fev 2013 and still strugling to set up with Preamp kit.
Voltage is never stable & got huge buzz too.
They updated new shematic & BOM some weeks ago, so PLZ check thier DL links.
As for 12ax7 phono PCB, there are one thread quite helpful on this forum too.

Hej Guys! The problems with the HV400 sound all too familiar. Missing parts, and a list of parts refering to non existing numbers om the PCB...
So far very friendly replies, but no real solutions.
Still trying building a complete phono kit here. What doesn't go easy makes me smarter, ha ha haaaaaaaaaaargh!)
