I am interested in adding an additional single color LED to my Cornet Front Panel. Where could I wire it into near the front of the circuit board for this purpose?

I wonder if you could just run a jumper wire from the two color LED to the front.  I would not mix an LED into the circuit because LED's are noisy critters.  I would not want that noise landing back in the first tube's gain stage.

Ask Jim if the LED he specs is 120v or some other voltage amount.  If you piggyback these you could run the double color on both ends.  That might be fun.  You can also get double color LEDs in different configurations.  Maybe go white to red / red to white. 

Go Canada!

I like the color scheme! Actually, I just want a red one at the front for a bit of Bling. Any suggestions Mr. Hagerman?

Easy way to add an LED is to borrow some power from the dc heaters.  That hole in the center of the 12AX7 sockets is 6.3Vdc.  You can tap into it, add a series 1k resistor or so with an LED to ground.

Thanks for the tip Jim. While we're on the topic, I am going to direct solder my RCA's to the circuit board. I am assuming that the input can go where the mono switch would be and the output would be off C208? Could I just solder onto the leads of the Cap, or is there a better solution? The reason I don't want to solder onto the RCA inputs is because I want to shield the whole power supply area with copper foil and ERS cloth.

Yup, that should work fine.  Can go straight to leads of the cap.  Connect return to a nearby ground.  Doing so is far more important on the input.  You MUST use a ground point right by the input tube.  Pin 9 of the tube socket works best.
