Server cabinets are great. Especially for my OTL’s 😬

These suggestions are awesome! I’d love to do a server but the space is limited.
For the face, I’m leaning toward a large led display covering the entire panel. The display would show a spectrum analyzer, dbW meter, ground resistance (with GFM), and coolant temp. Actually for the coolant loop temperature monitor; it would be cool to show the ambient temp inside the chassis also, then display the delta T of the coolant.

These vintage tuners look great, I’ll try to incorporate This into the front panel in some way.
I actually have a round oscilloscope bezel & screen from an old Eico, that might make its way into the build.
No magic eye? And man, you need such a larger chassis. It should have multiple naked toroid transformers mounted on the outside of the chassis.
HAHAHAHA..,
Nothing like walking into a cold airplane on the flight line, before sunrise, and hearing the Big Shot Pilot proclaim they don't want to use the APU because they got fueled up last night, don't want to refuel during the flight and they're waiting for the cart... so you all wait huddled in the van cussing up the Colonel or whoever made that decision.
An APU for a stereo, sounds to me like a wonderful idea.
Can't get rid the flight test engineer in me.

I looked into the Peltier cooling option. It's a very cool principle, but unfortunately, it's very inefficient.
As an example, 6 of these modules would be required per channel. This requires 1.1kW @ 15.4V overall to support the max in-rush current and for 720W average for constant operation.
With this in mind, water cooling or maybe phase change cooling may be better options.
To be honest, I got some reservations about a CJ "copy". No way did CJ allow such a copy... they are adamant about keeping control over their stuff, even maintenance and repair. I got a PV9 and ET3SE (line stage), both with their CJ branded Teflon caps... which elevates them incredibly over the stock units (also use Svetlana tubes).
All of the work has been done at the factory.
You got to respect IP.

I agree with respect to IP and the value of CJs work.
This “copy” definitely deviates from the original design. I purchased it because the schematic and quality looked reasonable. If it had a different name I would call it by that, but unfortunately it doesn’t.
We can refer to it as the “SE tube preamp” for the duration of the build.
Also, the tubes and big caps didn’t come with the kit 😉

Cooling solution is being sorted out.
The current internal struggle is in deciding between dual cold plates or one single plate (serving both amplifiers). I believe the former is more widely accepted, but it will increase cost and complexity of the coolant loop.

Received cold plates and radiator for the Aleph coolant setup. Haven’t had time to make a CAD model and plan the fabrication of mounting parts, this may or may not happen. Worst case, things get built on the fly.
Coolant reservoir and pump are not on hand yet, but they should be easy enough.
