2 years ago i have designed a modern HQ swallow psu for small or medium Buchla system or other it ‘s easy to make a 5v -12/12v ,just swap the dcdc converters ,there are 2 pcbs psu alone +splittable distroboard you can cut it
as you need
This one has ALL the rails isolated,in the 211 the 5v is a cheap dcdc not isolated.
inductors and capacitors filters ,pull up for 200e i2c bus,filtered ,separate N and Q grounds ,all the voltages you need .
EDIT for small system up to two modules 2 (modules ports ,)only the pcb psu is needed
edit :THIS PSU FITS UNDER A 208 MODULE IN A STANDARD BOAT 150mm X 58 mm under the seqencer section
small ,perfect for easel 208/218
5v 2400mA 2,4A
-15v 400mA 0,4A
12v inductor filtered too,after the external brick (cheaper option)
or as an option ,if needed HQ ,(high quality) i use a IC 3. ,12/12v dcdc too
feel free to ask technical info
Soon mouser bom ,prices
built infos here
+ another pcb ,its a distroboard filtered etc splittable ,if needed
