L-1 VOCODER for Eurorack.
Module wide 32HP, deep - 80mm.

It is PCBs and panels for making 24-channel analogue vocoder.
$35 per board, 5 boards total = $175
Frontpanel 32HP - $40 (frontpanels are with or without cats, please note which you want)

You can order any quantities of boards or panels, not obligatory full set.
Who want to order more than two sets, ask about shipping cost.
WHERE TO BUY COMPONENTS?
IMPORTANT! THAT4301 is obsolete. Please buy chips before ordering the kit (25 of THAT4301 are needed). Or order replacement chiclet from Synthcube: https://synthcube.com/cart/that4301-replacement-pcb-chiclet-that4305-dip-20
I noted by different colors which components are included in kit, which are better to buy in Tayda Electronics, which are included in Mouser shopping carts.
In Tayda Electronics I recommend to buy potentiometers, film capacitors and between boards connectors. Links are in the partslists.
HOW TO TRIM COMPRESSOR DISTORTION SYMMETRY ON CONTROL BOARD
Disconnect everything except of power. Measure DC voltage at 12 pin of 4301 when compression pot is on min, then on max. Trim trimpot to make these voltages equal. It's a bit more than -2 mV on mine.
