Hi,

This project includes Volume Control and Selector Control IN/OUT Boards.
Also includes 7-SEGMENT display control by < > and UP - DOWN push switch.

This project can connect to (instead of) all circuit which use ADC0804 for STEP ATTENUATOR it also has Dual Mono Power Supply +/- 33V if you need to build your diy preamp such as Pass X0.2 or UGS

Remote control is option.

Thanks
Anadigit

Step + Preamp

I have some prototype PCB which use for this IN/OUT and STEP ATTENUATOR, it's look like pumpkin preamp but there're something different his designed such as input/output impedance and bias current and balanced/unbalance configuration.

If someone interested I'll make a PCB group buy,

Thanks
