What's B+ before R30 = 10K, do you sell the PCM board only for MC?

B+ is about 150v, but between 120 and 160v will be good.(current 2.8mA).
This B+ comes from the MM section and is already very well filtered with CRCRCRCRC. If you only want to use the MC pre you need a good stabelized B+ and regulated heater supply.

Sorry i do not sell PCB's, but your free to use the PCB film design.

The black text ones are rebranded 6H16-I types not as good.

Smile Nice!!

Hi, excellent stuff!! I am planning similar with 6N17 BV since it has more gain. Is there a specific reason to use 6N16.
Can you sell me one MM circuit board?
Regards, JJ
