hello all, just picked up a Kustom III head, Kustom 2x15 cab and fender 1x15 cab for almost nothing. looked up the serial number for the head which dates it to 1977. head powers up, but I'm getting no sound plugged into either cab. not finding much info about this model on line, anyone have experience with it? any ideas? thanks!

So when you turn it on there's no light pop out of the speaker(s) or hiss if you put your ear right up to the speaker(s)?

You will need to slide the chassis out of the cabinet and get the PC board numbers off of the 3 or 4 circuit boards, and also take some photos/ gut shots to send me and then I can likely help.

If there's any good news, atleast it's not blowing fuses!

Have you tried to clean the molex connector plugs between each of the circuit boards?
