C12 with Moby's V2545

[dmp]

Beautiful!
The plexi boards are difficult to drill yeah? But makes a nice mic

FLEA pre-drilled them, but I actually ended up drilling some additional holes. It wasn’t too bad!

great work! how did you translate the schematics to the original P2P wiring? I have thought about doing this myself, but as an amateur that has only assembled simple tube preamps and Poctop's PCBs, it is pretty daunting work.

I studied many old pics and also just mapped it out using patience.

Somewhere I ran across a layout image someone else made. If I find it in my documents, I’ll share it!

I draw one a few years ago, and use it in my C12 Flea clones.

Inspiring build! I've been starting to piece together a DIY trio of C12s and hoping what I wind up with close to what you've got here.

I'm about to pull the trigger on the Flea bodies but don't want to pay for the swivel mounts. I've got a couple for my 251s anyway that I believe are compatible.


Where'd you find the connector you wound up using?

Do you have any more details on the power supply build or track down the schematic you used?

I think I'm gonna stick with the T14, and know they're compatible but it sounds like people make a few changes to handle the lower voltage from the SM204.

Beautiful mics and amazing sounding！ Thanks for sharing.

The connectors are used old stock and bought from a private seller on Reverb.

If I had it to do over I probably would’ve bought the swivel mounts from FLEA; the old connectors plus shockmounts didn’t end up being much if any cheaper

@soapfoot you inspired me to build one of these. I used:

• MBHO/Haun CK12
• Moby V2545
• GE 5 Star 6072 triple mica
• HT11A body
• parts I had on hand

It sounds great!

Nice one!

Thanks for sharing the photos. I'm building a very similar version. How is the transformer attached? It looks like it's just floating in there.

I used double-sided mount tape, since it's a pretty tight fit. The B+, H+, Polarity, and Bias wires also help to stabilize the V2545. I previously built a C12 with a V2545 mounted on a board with the rest of the components (tube on small daughter board, as Poctop and Matador did). In both cases I had to cut off the "corner folds" of the rails to make enough room.

Oh yes, I can see it clearly now. Thanks so much. I'm doing point to point too so this is helpful. I've seen people use zip ties, but the tape looks like a good idea.
