I just build my second unit after totally killed the first after connecting the front PCB the wrong way. After trying to remove the angled connection, I damaged the PCB. So I ordered a second one, which I got ready to go.
It doesn't work as expected, one channel does not give any sound, although the meter is corresponding.
I have got 2 pcs of NPD5566, which I got from China. What would an appropriate replacement for that? I can't get no answer, beside the bf245 in this thread. I'm not really sure, if they are working.
I think, something in the output section seems not to work. May the output transformer is not giving the signal, cause I built adapter-pcb for edcor xs 1100. On the IC, the current seems to be fine, I'm not getting through the schematic where to look else or how to measure, if the transformer is working. Should I get an audoi signal at the outputs, when the transformers are removed?
Thanks, it is getting frustrating.

Might you please explain your Post Gustav?

Greg, I think, Gustav means that the middle row of the pot pads has no function and doesn't have to be connected.
I did not do this, but I used wires with connectors, which I want to remove to See, if something is wrong here. Unfortunately, my soldering Station is not working anymore, the new one should arrive soon. Thanks for your suggestions, Gustav. I will try it soon.

You could set a fixed release to get you going
Hope it works out.
