Fab,

Black PCBs look nice and are quite common for high end PC motherboards, video cards sound cards.

Our USSA-5 amplifier PCBs are also black - so it will be a nice match.

Guys where are you procuring the matched 2SK2013/313 mosfets either for this preamp or Fab's USSA5 power amp build. The only known source to me was member liubincalvin from Singapore, who seems to be inactive now since some months now. Any other source to get these hard to find power mosfets?

Thanks

Default Boards Delivered

Hi Fab,
I received the USSPA pcbs today, thank you.
Very quick shipping from Canada!!
My aluminum chassis will not arrive for a couple of weeks so I threw together this little wooden case, it will have an aluminum front panel also.

Any idea about the genuineness of these mosfets and as the site says with additional $2 he will do beta match. Not sure what is beta match.
