Help to repair CAT JL1 monoamp?

Ken Stevens may be a little odd but he is very much on top of things, I would give him a little more time to get a hold of you- after all it is a holiday weekend. Or I agree with the idea of getting in touch with a dealer.

Jtinn is a dealer and took the amps he has for sale in on trade and would not be able to help you much if at all.

How long ago did you try to reach CAT? I would suggest sending a fax if you can. If they don't respond then drop me a line and I'll ask a friend who's a CAT dealer to see if he can help you out.

Perhaps the factory is just closed for the holiday weekend?

never had an experiendce with factory but you can look-up to the functioning monoblock and figure out resistance from either color code or measurement with resistor taken off the circuit.
than you can order neccessary values from partsconnexion.com that have very fast service.

how old is your unit?

some wierd blow you've got with further circuit damage.
that tells me that there is something more is at fault to be further checked throughout supply path and even signal path as well.

This makes no sense. The factory has always been responsive. Have you left a message?

I noticed that Audiogo member and dealer JTinn has a pair of these for sale so perhaps he can be of help to you. He is a heck of a nice guy to talk to.
