That should do it :) Hey Rob

I have built the same dual 811a coil and would like to add a staccato controller but am unsure how to choose the right SCR? Very nice coil.

Had the SCR hooked up incorrectly...LOL! Unbelievable! Had the SCR hooked up incorrectly…LOL!

This is what I could just think of, might be something else :) Kind regards Mads Hey Richard Harris

I just completed the staccato part of my single 811-A tube coil, but for some reason R18 (being the 100 ohm resistor in your schematic) keeps getting extremely hot. The half watt resistors kept burning up, so I put in a 2 watt resistor, and that puppy starts smoking if the coil runs for too long. Everything seems correct on the board, as I have checked it several times. Could I be hooking the SCR up incorrectly? What do you think would cause this problem?
