It is the perforated sheet..I need to move it down one row...too lazy to do it now.

It was something that I picked up at a surplus electronics parts store..I had the case powdercoated. It used to look like this.

And this is how it was when i picked it up from the surplus store..

Here is a CMOY I built years ago. It's built into piece of furniture for a doll house I picked up at a crafts store for about a buck...

Nice work, Big Dave!

Thanks for the compliments, guys, very much appreciated.
The PSU is my design, nothing special just +/- 15Vdc via LM317/LM337 on a home etch board. The pcb after it is a JLH PSRR, which detects noise on the DC and then cancels it out, followed by a cap. multiplier. Used in the AK-SCHA, and also used here, it makes a huge difference. I was part of the team that made the professional boards, with me doing the layout. The main board is a modification of an australian version of the classic Class A amplifier. It's been modified by SandyK, and can now be used with headphones, but with further improvements to the SQ via a modification to the input LTP. Board home etched by me.

The nice chunky cable is Van Damme classic XKE instrument cable. Very flexible and nice to work with. The stepped attenuator is due to be replaced by LDR's (Lightspeed) when they arrive.

Here are some pics of my most recent work… a single ended transformer coupled one-stage tube amp.
It’s a kind of tinkerman project, intended to try out some good sounding tubes with high Gm and high Mu like D3a, Russians 6J52P, 6S45P-E and 6N30P-DR.

On the picture are D3a tubes with a level meter tube in between, the Sowter OPTs are on the back.
The power supply is housed in a separate enclosure.

In the middle is an ε24 circuit driving a Sharp solide-state relay.
Thanks Ti (amb) for this handy circuit!
