Thank you very muchIf the bottom is thick enough, you can also drill a 2.5mm hole and use a 3mm x 0.5mm tap to make the threads in the case. That's what I did.
Example for illustration only, I don't know the quality.

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

Well noted, thanks Bill.Eric,
Thanks, I have plenty projects to keep me busy for now but just letting you know I still have interest in the FFA003.

I will PM you immediately once we're ready.
Thanks,Eric
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.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?
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.

3 FFA001 modules (I ordered them way back near the beginning of this thread) drawing from one IEC mains connector works fine.

I’m very interested as well. I’d lost track of this thread but now my interest is rekindled. I really need to read through this againEric,
Thanks, I have plenty projects to keep me busy for now but just letting you know I still have interest in the FFA003.
