SOLD
Up for sale are two complete assembled Gyrator boards from Bartola.
They are ideal for low current DHTs like 26 and 01A but other tubes also can be used but please consult Ale from Bartola valves!
All the parts used are high quality! I will include also 0.1uF obbligato 630V film caps! I used matched 2sk170BL transistors also!
Price: 35 USD / assembled board
For actual pictures of the boards please send me your e-mail.
I am shipping worldwide!

Can this be used for a 300V, 30mA preamp supply? If so, what are some of the specs about the circuit?

2SK170BL: 6...12mA.
It's perfect for #26 or #01.

Hello,
I think you should contact the designer of the boards.
