I think I may have to move the preamp boards over to my Etsy shop as it’s too hard to keep track of the occasional request for boards here on a GB format. I will need to order more boards as all out at this point.

The daughter cards contain the core amp module. It lets you make different ones to tailor to your needs. Gain, headphone amp, bias current, components, etc. swappable gain is a useful addition to any preamp. The cores are very cost effective.
 
...I am using an RK09 Alps pot from my pocket amp and attached a short piece of vinyl tubing to allow the shaft to be operated from the front...

What do you -and others- think about Vishay Cermet pots?

Cermet potentiometers – Audial

Cermet potentiometers of course are not new, but are still relatively unknown. The reason they are used in the Model A is simple: they are sonically clearly superior to any other potentiometer type.

Still, they (apart form being somewhat fragile) have one shortcoming too: low level inter-channel miss-tracking. I am not aware if this was discussed previously anywhere, so more information on this follows...
