Can somebody please point me to some information/illustration of the wire connections between Gnd1/Gnd2 on the 30dB volume controller board and Net Tie J4/J10 on the pre-amp board?
I'm having a bit of trouble locating both😕

Hi Nicmac, in this post it shows how to connect the grounds to an angled connector that then connects into a female connector on the relay board: Post 386

Example Arduino sketch to control VolCB board
I put together the attached Arduino sketch. It controls Hans Polak's 64-step VolCB and 4InputSelect boards. For simplicity, it uses two rotary encoders, one to select input, the other - volume. Use it as a starting point.

Hi,
I'm interested on these:
- Bare PCB for Hans Polak's 3-way balanced input selector with a pass-through
- Bare PCB for Hans Polak's 64-step relay volume controller
Is this project still running?
Thank you for the effort and your time

Sorry to say this but I have none of the PCBs you are interested in. (I do have a few BPPBP and 16-step volume control board left.) I do not plan another run as there has been little additional interest. Thanks to Hans Polak's publishing the gerbers for his boards, you can order some PCBs for yourself though.
Thanks Alex, I think I'll try the 16 step one then (I have a few boards of those as well) with the extra Relay, if I manage to understand how to do it properly. Regards!
Hi Alex,
Are there any PCBs left. I’m interested in BPPBP AND 16 step Volume board.
Thanks
Kemp
I have an extra set of : input selector board, one preamp board and one 16-step relay volume controller .
Thanks, I have ordered a Balanced Volume Control Board from your website. So don’t need preamp board for now. Still deciding about which volume board to go for...

Alex, can Hans 16 step board be used with your board I have just purchased. If so, I may be interested and will send you pm.
Thanks
Kemp
Thanks

They probably can - the topologies of the volume control part on BPPBP and my boards are identical, so it should be possible to replace the pot with a VolCB boards from Hans. I never tested it, but I see no reason why it should not work.
Thanks, Will try with Hans 16 step board to see how it works.
How to order for one 16 step board. Please advice.
