Hi, Bill

During mid of this month, the I/O buffer with DIP opamp/Volume control will be ready, then we can open the first -batch order for friends. Sounds a little delay than the schedule. while more resources are put into working on the universal FFA002V2

Thanks,Eric

Hi. I bought and received an amp with unbalanced buffer board and am just now getting round to building a case. My question is how do I connect a volume pot to it, and what impedance pot should I use?

For the current I/O buffer circuit design, I don't think there is a proper way to wire in the pot. It's better to have a pre-amplifier for your system.

Thanks,Eric

@Randy Bassinga you might go back and review the six channel by @von Ah (here and in other threads). IANA[EE] but if three boards coexist, changing the power limiter on one channel doesn't seem like it would make them fight. If you need more power than (whatever the base power line is there, it's ~15A here) you are now into breaker limits and separate lines run from the main power box anyway.
