you bet!
'Must have been from a workbench or something. I cut off the section that had the mounting holes...
I scored them thinking I'd use them as a basis for home made heat sinks but in this application I just like the curve

I looked up that car on the net, you pay me a high complement!
I used to think I wanted to design cars. It may still be in my brain somewhere; yes it does look automotive now that I think of it in that way...
Did you see this other design of mine? Someone said it reminded him of a 10 cylinder motor

The emblem on the front resembles that of a Chevy Impala.
10 cylinder air cooled boxer motor....OK cool.....no maybe rather warm. 10 processor coolers with no fans.
Actually both are quite unique and look good. I like the steam punkish overtones without all the unnecessary added junk that adorns many steam punk items.
I once made a V8 tube guitar amp. 8 output tubes, 4 each sticking out of a piece of corrugated aluminum hurricane shutter that I picked up out of the street after a storm. Sadly it looked far better than it worked, so it got trashed.
Broskie Aikido stage driving cans. Only tested with my 32 ohm gaming headset tonight, will get some listening in tomorrow with the Fulla and my AKG K240's. Still as impressive as it was on the PCB. Dead quiet this time though, suspect my wiring on the PCB's to test was causing a bit of hiss. Now it quieter than a church mouse in a library. 6N6 and 6N1 tubes driving the whole thing. For mother russia! Indicator light on the right isn't wired in yet but will be soon.
Thanks, doing a little critical listening today on my other cans and its not nearly as bright. Suspect that could have just been the cans i was testing with. Still sounds like I'm taking some of the mids out with it (compared to directly out of my Fulla). Hey there's a cowbell I didn't pick up on before though! lolol.
I wanted to add in a low/high gain feedback switch yet to help when driving low Z cans as i suspect that may be part of the issue. The WCF was never terribly amazing at Z < 100 so some NFB will kind of be a "two birds with one stone" thing. Additionally I may just make the extra resistor in low gain mode be variable, with a cap for a HPF. help bolster the mids and lows a bit.
More tinkering to be had! Overall still a great design.

It's been sitting on my desk all day now and after 5-6 hours of burn in with the tubes they've mellowed out quite drastically. The Fulla I'm feeding it with is already bright so I think with the cans I'm using and that DAC I'm getting a very true reproduction. Still going to come back to it tonight and add in a hi/lo gain switch and finally wire in my indicator.
Morrison Micro 2A3
Some pictures of my Morrison Micro 2A3 build
The version I built is slightly different from the schematic as I had parafeed transformers and chokes available.
J.C Morrison's choice of operating point is a bit unusual as there is nearly 80mA plate current on each 2a3. I tried altering resistor values to achieve the 'classic' 250v 60ma point - the amp worked but the magic was gone so I'm sticking with the original design and hoping my tubes have a reasonably long life.
The power supply is in a separate box - photos to follow once I have tidied it up a bit.

My Last Project, a Gu50 Tube Amp (Designed By Momchil Damyanov - Bulgaria)
Separate PSU, 5 watts of pure sound.
Some details missing yet like cover for the power trafo and take care of the psu´s wooden box.
And a video Here (Yes the speakers are not in the best place)
