I've got a K50-2 that isn't working and there is a burnt up resistor that needs replaced. Anyone have a schematic for it?

thanks

Sorry, I do not, but can you post a picture of the board and the resistor that is burned up, as I may be able to help you from just that.

Here are links to a couple pictures.

Hi, unfortunate but the k50 board is a board unto itself as it seems, but if you tell me what other board connections are at each end of where that resistor came out of I may be able to help find its value, if that part of the circuit is like a K100 layout.
Also that part of the board is burnt up form that brown square 200 ohm 5 watt resistor, it gets real hot dropping the voltage to the pilot light. The board burns to some extent on all the combo head K100s that mount that same resistor on the board like that.
To fix that problem you can eitheir extend the resistors leads and support it with a blob of automotive high heat red silocone, or get a new resistor and some brass tubing from a craft store and cut 1/2" long lenghts that the new resistors leads will pass thru, and the tubing will support the resistor.
