Few pics of my diy stepped attenuator. The stepper is from ebay.

Uraltone HIFI PP-EL84 diy valve amp kit
URALTONE diy valve amp kit sold by, you guessed it, uraltone in Helsinki Finland
http://www.uraltone.com/uraltone-stereo-hifi-pp-el84-v1-1-tube-amp-kit.html
Fun build and teaches you a lot about soldering! I did this just to improve on my build skills, but eventually sold this off too.
Sound quality is very good, and you can adjust the "feedback" via a rotating switch. I did have most issues with the input grounds, ok maybe my soldering skill were not up to par back in the day. The input signal wires are very very small and the input selector and volume attenuator is a bit tricky to solder.

Diy speakers. Diy veneers.
Just a small recap of DIY speaker builds. Diy all the way. Sold them all off.
Audiokit AW 10x coax (zebrano veneer)
Basic speaker build kit with coaxial speakers by seas. These were pretty decent, but expensive elements. limited in bass depth.
Making of - pic from the Aw 10 coax, I made 3 cabinets and in this pic two have been treated with osmo top oil. Makes a huge difference in color.
Picture is before Osmo finishing "top oil" wood oil. Zebrano veneer is a absolute pain in the ass to work with, very fragile and "stiff".
Audiokit aw-10 excel (walnut veneer)
Making of -pics
I made the cabinets out of 15mm birch plywood. Very overkill for such cabinets. I did not build the cabinets with miter joints, which was a big mistake.
This is before the wood oil treatment. Much less contrast in the color. The wood oil is very sensitive to wood glue stains. Be warned.
Veneer before cutting. Cutting them is the most difficult part of the process. I would suggest leaving it to a professional, and if he has a veneer cutting machine, even better.
Walnut veneer test with shiny laquer. Would make for a very contrasty and rough look!
Hifimaailma HM100db/w with Aw 10 excel
The price you pay for diy speakers. Sometimes they end up like this:
Listening tests with Hepokatti.
Uraltone hifi pp el-84 Diy tube amp kit. Pretty decent amp, but lacked some "attack" for my liking. Sold off as well.
