I am sorry, Gentlemen, to tell you that this little project will be delayed due a "not-on-stock - condition" .
I have ordered a couple (16) of NSL-32SR2 last week from RSOnline, but due to the component number 250xxxx,
these components are not on stock generally and have to be ordered from the manufacturer on customer's requests.
I have been told from RSOnline that the LDRs will arrive next week latest.
If I had known this restriction beforehand, I would have ordered from FARNELL, which have the LDRs on stock.
I am not able to cancel my RSOnline order.
I am sorry for this delay, but I hope that you (who are interested in this PCB) won't loose your interest.
In the meantime METAL and I are preparing to give you the best of hard- and software - solution available for this small project.
It only takes some time.
Best regards - Rudi_Ratlos

TELSTAR: I have been told from RSOnline today that a cancellation of my order is not possible.
RONNY: thank you for your kind answer.
In the meantime METAL and I have committed on a scheme that will be able to "understand / learn " the transmitted codes
of your remote-control unit.

I am very sorry, Adrian, to be not able to provide you 4 input sources.
The number of input sources is restricted to 3 due to the current layout (size of the PCB: 100 x 100 mm).
I have been asked by a number of German FC-100 group-buyers to provide them a remotely-controlled "PowerOn/PowerOff ("Standby") functionality" - and I will provide it - see the attached image, the leftmost relay.
This relay can be used to power on/off your FC-100. I will tell you how to do it.

P.S. I am still waiting for the ordered LDRs to arrive. Maybe on coming Tuesday.
Just let me think this over again. Do I really need a "Mute Relay"?

Gentlemen, I am doing some nice progress with my current project: "A general audio supplementary PCB" - see pictures attached.
The PCB includes the following functionality: George Stantscheff's Lightspeed Attenuator (being controlled by a motorized potentiometer),
Source Selection, Mute Function, 2 Temperature Sensors, StandBy (Switch the FC-100 on/off), LCD display, everything being controlled
by Infrared with the ability to learn the codes of your control unit, ...
After 3 weeks of waiting I finally received 16 NSL-32SR2 Silonex opto-couplers and measured them at different currents flowing through the LED.
This is the result:

There are at least 4 pairs of LDRs that match very well and can be used for George's "Lightspeed Attenuator".
METAL, who did the software part of this project, has provided me an absolutely fail-safe, professional program for the used PIC µProcessor.
I have "cannibalized" an old SYMASM to test the functionality of the PCB in real life, before I will "marry" this PCB with my GEM-amplifier,
the FC-100, which still is "the very best DIY-amplifier that I have ever listened to".
I will keep you informed about my progress.

P.S. The image below shows the prototype PCB. The layout of the final PCB is shown in post #518.
