I'm new here and it was nice to find this site, great job. I went through the postings and didn't find the answers I needed but did find a lot of good stuff.
I have a couple things to ask about if that's cool. I picked up a K100-B5, 4 channel PA head. There are no markings on the back of the amp (besides serial #plate) as to which are 1/4" output jack. I would assume it to be the 2 together up higher and in the center and the lower right had corner might be for a reverb foot switch? Also there is an RCA jack, is that standard?
Now for the cabinet question, as most of the wiring was totally gone inside when I got opened them, are they wired for 8ohm each for a 4 ohm load at the head?
Lastly, just wondering if you will be able to get the schematics back up? Retired road guy now playing for the fun of it, but I can still read a schematic.
Thanks

Hey Hawkeye,
Welcome to the site.
You are right - the two jacks that are together near the center are the speaker outputs.
The lower right jack is for a reverb footswitch.
The RCA jack is recording output.

The minumimum load for a K100 is 8 ohms.
So your speakers should be wired so that each cabinet is 16 ohms.
Both cabinets together would be a 8 ohm load.

Silver, found it at a pawn shop. Not a scratch on it. The speakers are a bit tough, but just for rehearsal room they're OK.
I found a stand for the head but need the clamp set for the cabinet, it just has the screws left in it, any ideas if those can even be found anywhere?
Thanks for the info too!I appreciate it.
