The 1st German DIYer completed my "General Purpose Lightspeed Attenuator" - PCB, connected it to his amplifier and
is very, very content with the result.
I will wait for the feedback of some other DIYers.

Best regards - Rudi_Ratlos

P.S. He did not yet connect the temperature sensors; he will do this this afternoon.

Hi Rudi,

just finished building the attenuator. Not tested yet soundwise and i think i need to wait until monday maybe for this but so far everything works fine.
I've noticed the motorized potentiometer is having some large imbalance between L and R total resistence and also imbalance in intermediate positions of whiper. (95k&87k total resistence each channel)
I would be interested if you or someone else measured the potentiometre values in different positions.
I was asking myself during build why Mr Stancheff did't installed two potentiometres for shunt LDR's also, there is a reason ?

Thanks a lot Rudi for this nice kit !

Adrian

Gentlemen, from time to time I receive a request concerning the availability of FC100 - PCBs (AMP and Shunt).
Currently I do not have any PCBs left, but I will order a small couple of PCBs in the near future - if you like!
I will not provide you any components (like transistors, capacitors, ...) this time.

The price will be 12 for the AMP-PCB and 10 for the Shunt-PCB.
Shipping is 3.45 worldwide.

I will wait with ordering the PCBs until the minimum amount of PCBs to be etched (10) has been reached.

Best regards - Rudi_Ratlos
