 Of course, another option would be to add one of [BobSchleicher]s (or another type of) 
 [SolidStateRelay]s. 
  
-Note: These component values vary from the ones shown in the [version | http://tonewheel.com/Schematics/adapter.zip] of this circuit on Bob's [website | http://tonewheel.com]. That version shows the 56k ohm resistors as 2.2M, and the 1M as a 56k. 
+If you use a TIP102 for the darlington, it has internal resistors between the base and the emitter, so the ''1 Meg'' resistor can be omitted. (I also used 68k resistors to the [G-G]s rather than the 56k on the schematic. Worked fine.

+As for the relay, Omron P/N LY1F-DC24 or Potter & Brumfield P/N K10P-11DT5-24 will work. (As will many, many others.)
