I ended up using the #TubePreBuild at a live sound gig yesterday on lead vocals. Sounded great. Can't wait to build another.

Ricardus (ricardus)'s status on Monday, 15-Jul-2019 22:54:56 UTC Ricardus On thing I apparently forgot to post about in this build thread was the output balancing transformers I used. The preamp designer didn't balance the output for whatever reason, and just recommended using a 600:600 balancing traffo, so I went with Sowter 3603s. At first Sowter shipped me the wrong model. Had to ship them back (to the UK!) and wait for the correct ones, but they made it worth my while. A friend 3D printed me some custom holders/brackets too which worked perfectly.

Glad things worked out. Yeah. Check the tubes first! ? Where are you located? Where do you get your tubes?
I just finished a dual channel tube mic preamp. If you're interested you can check this hashtag:

Ricardus (ricardus)'s status on Monday, 15-Jul-2019 21:48:29 UTC Ricardus I was listening to the PMillet tube pre with my better condenser mics. Sounds pretty damn huge to me. Killer. Definitely have to build another one of these in the future.

Ricardus (ricardus)'s status on Sunday, 14-Jul-2019 16:01:07 UTC Ricardus The two channel version of this pre is officially finished, unless I buy the FPE custom panel I designed for it.
After talking to the designer in email, he was confident with an off the shelf switching PSU that has a proper ground, I could get away with putting that in the case because of all the filtering he designed into the circuit.
Outputs are balanced with Sowters.
Sounds amazing. Might build another in a few months. -

Ricardus (ricardus)'s status on Monday, 10-Jun-2019 20:48:09 UTC Ricardus So I got a replacement PSU for the preamp, and it's putting out square waves also (it's a DC power supply). Nearly consecutive serial numbers (xxxxxx04 and xxxxxx06), so I'm thinking the manufacturer made a defective Lot. I've been on the phone with the manufacturer and the dealer who sold it to me. All I want is one that works!

Ricardus (ricardus)'s status on Saturday, 08-Jun-2019 22:31:57 UTC Ricardus I went to work with the P-Touch. It's not awesome, it's not awful. It's somewhere in the middle.

Ricardus (ricardus)'s status on Friday, 07-Jun-2019 16:12:12 UTC Ricardus The build is basically done. Had a small power supply issue so I haven't really been able to test it yet. Will post pics when that happens. In the meantime, I put the schematic on the inside of the upper rack box lid, OLD SCHOOL, so long after I'm dead, if someone is still using this, the tech will have a schematic. Lots of old gear used to do this. They don't anymore.

Ricardus (ricardus)'s status on Sunday, 02-Jun-2019 13:42:20 UTC Ricardus I think this thing is done... except for the PSU which seems to be putting out some very dirty DC. Must be defective.

Ricardus (ricardus)'s status on Friday, 31-May-2019 19:10:13 UTC Ricardus Did the XLR jumpers and put the tubes in. Shit's getting real.

Ricardus (ricardus)'s status on Friday, 31-May-2019 19:06:16 UTC Ricardus PCB offsets are mounted. Might shim them a little higher because they come with long screws.

Ricardus (ricardus)'s status on Monday, 27-May-2019 22:08:08 UTC Ricardus I also soldered the jumpers that will go between the PCB and the switches and pot on the panel. Each of the 3 switches has 6 wires, and the pot has 3. This was time consuming persnickety work, holding the wires at the right depth as I soldered. I ended up doing 2 wires at a time and using both of my Panavises.
