Yet another new guy.....uffa!

Been lurking around for a long time, figured it was time to come out and post some pictures, perhaps it will help others in their build (you know who you are...hi LeGrace). I build the two slightly different, routed some wires around different ways on the second one. Have to take some pictures of them done, but trust me, they look just like the other ones other than some fat Chinese feet I installed on each. Decided on the KT120s from Jim. So far so good, been pushing the amps hard for several weeks now and they just keep playing wonderfully.

Very nice!

Looks nice but:
filament AC should be twisted all the way and kept as close to the chassies as possible, avoiding
especially points/circuits where signal exists. This is to keep hum down.

Good point, thank you! It didn't occur to me it was that critical. They are both dead silent regarding any hum, even with the pre-amp volume turned all the way up. The only thing I do notice is with the pre-amp powered off, and if I stick my ear close to either speaker, I hear some RF. But as soon as the pre-amp is turned on, it goes completely away.

Thank you gents for the nice comments. It was a lot of fun building them. It reminded me of the old Health Kit days, when me and my dad built 2 25" color TV sets, one for us and one for a friend. What great fun it was to dive into projects like that.

LeGrace, I twisted the green wires together from the output TA for purely wire management purposes.

ALL wires from the power transformer should be twisted since they are carrying AC voltages! twisting AC wires reduces any hum

Nice.

Where did you get the blue flexible "Helping Hands" holding driver board in third photo??
They look like the work really well

Is one source. And that solder-dispenser is also very handy.

And, as this is in part a DIY forum, try this:

I made my own, it's more fun. If you decide to go the DIY route:

looks like the price went up on the aluminum, I bought the 6X10 1/2 for $16 shipped....shop around

Don't buy the tap until you receive the oil pipes. There are 2 threads, tap 1/2-20,and 14Mm-1.50...I goofed and got the 14mm first, but I needed the 1/2. But, it's a tool and I'm sure I'll use the 14 at some point....yeah right! Another good choice (since it's a soft metal) would be Harbor Freight (duck...incoming!). Taps from them is hit and miss, one turns to dust on the first crank (on harder metal) and another is as good as a Hanson or Bosch. I have seen great improvement over the years on the quality of some of their hand tools.
