|Steve A.||Re: How about a quick primer on EF86's?|
Do you have any tips for replacing the EF86 with a 12AX7? I was looking at an AC15 schematic earlier today and the EF86 uses a 220k plate resistor and a 2k2 cathode resistor bypassed with a 25uF cap; would you change those values? I assume that you would just discard the components soldered to pin #1 (G2): the 0.1uF cap to ground and the (x)Meg resistor to B+. And you would use the same value coupling cap (0.01uF) going to the Brilliance switch?
