Question B1 PCB

Are there by any chance still B1 preamp PCB's available?
I know they can be made p2p, but the final amp I want to make on an PCB

Hi,

when using a volt. regulator for 24V output, what should the cap value be on the output of the regulator and on the B1 pcb?

with the v.reg, you really don't need 30,000uF or they should still be used?

Default polarity

Does the B1 invert polarity?

Mouser has them, so does Allied. Or, use .5w. BTW, digikey is great, but most expensive.

What is the difference between the P-MEZB1-1V10 and P-MEZB1-1V10e boards?
