Test build of Super-Carbon up and running to see what is what:
PSU angle brackets are recycled from a previous, very tight, build, where those cutouts made perfect sense .
Two small issues worth mentioning on amp boards. First, TTC004b and PZTA42 have opposite pinouts (ECB vs BCE) so if using TTC004b, transistor front needs to face heat sink. Second, you need to add some current limiting on the CS LEDs if you intend to use them.
Running at +/-550V.
No listening yet; need to build a more permanent CS supply solution first and also tidy up in general.
