My tube preamplifier had made since 2005 JAN, and I still used it now but I want to redesign for complex circuit with 6DJ8 + JFET CCS
This board used 12V/5A supply with Switched Mode Power Supply Technology to transform voltage from 12V to 275V
This application also for line stage tube car preamp !
Quiet background and also isolated 12V input voltage from high voltage operation
I ask for 130USD (ECC83 SOVTEK 12AX7LPS + ECC82 12AU7 GE BLACKPLATE in straight forward schematic)
My pics are too large file, plz email me for them
Thanks
