Question Tosh PA4160 4 Channel Power Amp

I've searched and searched for a contact number for Tosh and can't find one anywhere. I've got a Tosh PA4160 4 channel power mixer that I've blown 2 resistors in and I need a schematic for it so I know what size to replace them with and hopefully solve my problem or at least get it working again to diagnose what the original problem was....which was the fact that everytime I turned it on and plugged anything into it, such as a mic or any other item, the fuse would blow.

Anyone know where I might find a schematic or a way to get hold of Tosh Electronics to get a schematic for that particular model? If I could get a PDF of the circuit board with the resistor locations and values, that would be awesome and make my life much nicer! LOL!

Thanks so much for any help you can offer!


P. S. I hope I posted this in the right spot!

Tosh Electronics Corp. shows up in a Google search as follows:

Tosh Electronics Corp
Bowling Green, OH


Don't know if this is current info or ancient. I have one of these which they also sold under the DeArmond name, I contacted Fender (who inherited DeArmond) and they don't have schematics for it.

Look at this 320047927999 item on ebay and you'll have a new one for $69.00, you can keep the other one for parts...

Max. cone displacement can be several foot on any speaker!Too bad it can be done only once......
