Thanks. It took some 3-4 tries to get it right. And about 10 years, lol. Whatever enclosure I built was never quite right. What you're seeing is a mashup of 3 failures . I did learn how to hide the mistakes and imperfections.

Here’s some photos of my 01A preamp based off Ale’s design. I’m using similar components, russian teflon output caps and russian wirewound resistors, rod coleman regulators with filament bias, and surplus military connectors for the umbilicals. I’ve gotten one channel tested and wired into my system, but am putting testing the other channel on hold for a couple more days until I finish up the chassis. This has been my first project not from a kit, and I’ve learned so much about layout, chassis work, and grounding. My wood shop teacher got some old cherry from a barn a friend of his tore down, I think they’re going to make beautiful chassis, I’m just worried my college dorm room won’t let me bring my stereo.Click the image to open in full size.Click the image to open in full size.

That looks great, adam1016! What connectors are you using between power and signal chassis?

Sodacose, they’re Military surplus connectors from ebay, using a 4 pin for filament +/- on each channel, and then 3 pins of a 12pin(?) for HT+, gnd, and earth. The actual cables are from McMaster.

I was always intrigued by "Magic Eye" tubes, so I bought a pair of 6FG6 tubes from a Ham Fest a couple of years ago. I found a pair of cheap PC board VU meter kits from Ebay China and built a nice Magic Eye tube VU meter for grins. I put 3mm green leds under each tube, hard to see in the pics, easy to see at night.

These were called EM87 in the UK and were installed on almost every European reel-to-reel tape recorder as a recording level indicator.
I still think they're pretty

Very nice as always!

I like the little bias displays. I had to check what an 8CB11 was.
