No Joe, they should ALL be bright GREEN :)

Face plate installed.

Got the sub face plate on, got her playing music using a PL3500 Peramp.

Got all the transistors installed. All voltages are checking out good. Bias set at .350 0v at outputs Wired up the front panel meters...

Take your time,

First test went well with Variac and DBT. Finished the control board, put in the first row of transistors. Did another test with just...

IN-deed. Smart, too. She was great in that part.

Kyle, I had to call in the "Big Dog" to assist us getting the shit done correctly and we can do a Proto Test Install here in a couple...

Yep I'm in the process of decluttering the plan so I can vector-ize it for CAD. I also rewired the regulator board and deleted R404/405

I may try to use photo shop or any other photo editing software to get the Jpeg down to just the 1 view instead of the 3 views which...

The format you want is DXF and I have the program to take a PNG or Jpeg, Bit Map, or SVG style image file, load it into the program to...

The CAD place I use lets you use the Tiff file to generate the Gerbers........... I should check my account because I may have the...

they look good. I'm going to try to get the image to scale and plug it into CAD, and see if I can come up with an STL and print a model

I just tested 10 1/4 watt 1% metal film and 10 1/4 watt 5% and they both tested in spec. As a matter of fact I just ohmed out some 40...

I would be curious about the Gain (hFe) readings on these newer RCA transistors. Real RCA 410 (and the exact same RCA transistor with a...
