If he can send you the schematic file, you should be able to run it in eagle and design a pcb.

When I saw your Eagle schematic, I thought you made PCB.

Thanks a lot, bimo.

Your welcome. Capacitors decoupling 100nF for NE5532 was not shown in the schematic.

Elektor Preamp 2012 (Douglas Self) with B&O ASX125-2 but now in one small case.

As a follow up of the earlier amplifier I decided to build the preamp2012 and the Icepower 125ASX-2 in one small case. Front size W x D: 230 x 40 mm.
The advantage is that no powersupply is needed as the 125 ASX-2 has a build in power supply (2 x 24v)
I decided to use bicolor Leds. Soft red for standby and crystal clear blue for on state.
Switching is done by a remote control. The output of the preamp and the input of the ASX are connected outside the case. This allows to use both amplifiers independed.

This approach makes my earlier set up redundant so I have to put the B&O icepower ASP1000 on Ebay.

See pictures.
