    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!

    Test each cab with a 9V battery placed across the tip and sleeve of the speaker cable connected to the each cabinet in turn. You should hear a hearty thunk from the cabinets.

    It should have a line out on the back, see if there is any signal there. If there is, then the power stage is toast. If not, then the problem is ahead of the power amp.

    Before getting too deep into the amplifier it's best to find out if the cabinets work. You'll never get sound out of the brute if the drivers are toast.
