I have a whole bunch of them -- been looking for a project to use them on.
What's on the workbench?

They can be photoshoped back in...
It lives! It doesn't squeal, whine, or hum! 3+ days off and on over these snow days (education has plusses and minuses) and finally sussed it out. Sushibox SmPS for plates (220, which is lower but fine) and a separate 12vdc supply for filaments and the Arduino for switching and LCD screen
3 Marshall preamp channels:
Parallel triodes 18watt with individually biased cathodes (lite iiB style)
Plexi with an M/N taper fader between dark and bright channels
Modded JCM800 from ampgarage ideas. Brighter but mean
This is a proof that I can do it. So now, on to the 4 channel Fender preamp, and then other fun preamps. You don't want to see the front - it's a repurposed telecom rack chassis from work

I have one pedal I need to bug fix with a similar “pcb mounts tube upright, but lay it down with wires across the pcb” - squeal city - how have you managed it!!

It has a screen?? What’s the interface for the switching? I hope this gets a detailed write up! People here have convinced me I want to build an amp, but I never even considered the possibility of DIY rack gear. This is a really interesting project/ category of project.

Definitely looking forward to this. I designed and built my own 7 Loop switcher with switchable input and output buffers. But yours looks so much more… tidy.

Brilliant!
I will run my 2 Klein Bottles into this:
Out of both Klein Bottles & the above OBNE's Signal Blender...
... which in turn will be routed into this Swiss-Cheese Thing's Orifices which in turn will run into ...
this:
#1,960
I may not even need to plug in an instrument or anything else. Just pure routing...
Honestly, don't know. Flying leads, solid grounding, shielded cable, and grid stoppers?
You know when you think something is going to look great after imagining what it could look like and then it's disappointing? That's this. Thanks JB weld!

Honestly that thing is awesome! I have build a lot of things in my life and I currently couldn’t fathom how I could make that. Polishing things off is what v2,3,4 ect are for. Nice work!
Hey, this thread is for what Robert is working on and for trolling what Bahb-bert is working on.
Communal workbench thread is over here:
yes, they could be named better.

I post stuff over there every once in a while just out of spite.
And don't bother reporting me, I know a guy ....
Ah crap. My bad.

Is that a project we get to build? Is that milliamps?
Robert
Reverse Engineer
Very soon, yep. I'm waiting on an enclosure from Tayda to verify that everything fits like it should.
Yes, that's milliamps.

Good thing I've been dragging my feet for a year on my own ammeter build. That's that aliexpress meter/display?
EDIT: Nice background staging.
