After I finish the Sun 2A3, I wanna build a 300B too!
Any ideas?
AudioNote Kit 1 300B?
AudioNote Interstage 300B?
Sun Audio 300B?
I have found both of the AN 300B schematic on line.
Also have you guys tried this Paper In oil cap from Russia.
0,22uF 1000V PIO capacitors K40y-9. I found some good review online
