The Filterbank funktion will have 3 modes: Capacitors I ordered my caps from TME with 5% tolerancer value - and measure they out to 1% |

Power Info from Juergen.H
Current measured on +12V and -12V was about 500mA each. This is without signal, and without channel LEDs.
Expect the current to stay below 1A (DC) with all LEDs turned on.
AC current (fuses after transformer) read 900mA each. Expect this to stay below 2A with LEDs and all.
So the 80W toroidal transformer (2 x 15V secondary) is slightly oversized, and exactly the right choice for thi sproject.Current measured on +12V and -12V was about 500mA each. This is without signal, and without channel LEDs.

Further along in those posts others warn they had to revert to the 100k/18k values because levels were too high. Sockets. |
