Please note that this amp and the K100 4-10" model uses a lot of FET type semiconductors which can not be checked like a regular bipolar Transistor .
I had one fail in my own K100 4-10 model a few years ago on that same channel like yours'

If you find you need to replace any of these be sure to use the proper anti static procedures!

Post script.
The only place I have ever found bad resistors in a Kustom amp has been in the output or driver stage, never a preamp stage, this may save you some time on the repair work !
