Just took purchase of an API console, so I'm going to start getting rid of bits and pieces that I no longer need or just won't have the time to finish.

Stereo BA283 Summing project 8 x 2
Collective Cases 2U case, Front Panel Express faceplate
Marconi style knobs, Hairball Meters
Carnhill input and output transformers
JLM STATTEN PCBs and pots for balance and gain
NOS Motorola 2N3055s, Styroflex capacitors like the originals
Inputs on TRS, Outputs on XLR
Unfinished, so there'll be troubleshooting for you. As such, I'm just looking to get the cost of parts out of this.
$850 firm, $750 plus shipping. Priced to move.

That Spectra Sonics unit looks great.
Did you do the PCB's yourself? is it your design for the faceplate?

What is that pcb on the input pot?

thank you

Someone else did the PCBs, but they're 1:1 copies of the originals. I did the faceplate design.

The input is a balanced-T pad attenuator PCB from CAPI, which you can look at here. I wanted to have infinite options for driving input and outputs, so I used this pad.

Thanks for the kind words.

Would you happen to have the Spectra-Sonics 101 Preamp schematic to share? And/or.....would you have any photographs or anything showing the PCB as a close-up and with details? If so.....I could re-create the 101 design for others. THANKS!!!

that's already shared and documented here on the forum, just do a search

it’s a really easy to do PCB, easy to self etch. Nothing complicated in this circuit

2x Banzai 'KM84' Mic Projects
Includes everything from the kit in addition to the 3U transformers, all parts from the BOM are populated, just needs biasing. I bought 6 additional NOS 2N3819 FETs in the event that something went wrong. They'll be included. Just don't have time to play with these right now. The kit alone was 351 CHF—$380 USD.

SOLD.
