Rek-o-kut M-12 and R-8A wiring diagrams / help

[JohnnyF]

Hello All,

Just picked up a M-12 cutter on a TR-12H turntable along with the R-8A amp via local auction. It was disassembled, so I need some help wiring it and getting it going again.

Does anyone have wiring diagrams or schematics for these?

I've got it just about back together; turntable is on and running, amp lights up and appears to be working, but I'm unsure where to run the wire from head to on the amp. As well, there is an xtal / magn switch on the back of the amp, and not sure what position it should be in.

Thanks for any help, advice, or manuals.

I'll update this as I figure things out.

The wire from the head goes to the back of the amp labeled cutter. A connection is available for for different ohms, and since this is an 8 ohm head, thats there the wire went. The other wire is attached to the terminal marked "C", as its the common wire.

Hi!

I’ve attached a photo of the Rex-O-Kut R-8A amp.
I took this photo while I was rebuilding mine.

Hope this helps you.

Bill, I have been looking for this days. Thank you so much for sharing this!

Thanks for the uploaded schematic. Is there any chance of taking 2 (or more) overlapping photos of the schematic such that the
resistor values and the like would be readable? As such, when I zoom in, the values become too pixelated to read. This picture is only a 600 by 450 resolution photo, and a magnifying glass is no help, either. I hate to be so picky. If you can't re-take sectional pictures,
what you have presented is still appreciated, anyway. js

Pretty sure the full manual is on this link (you just need to scroll through the topics or do a search on the forum) and if that fails then Google is your friend.....Rek-o-Kut Imperial might help to find it as well.

Another question to Bill: Was the R-8A schematic pasted on the amp's bottom cover plate? The cover plate is missing on the amp that
I'm working on. It's possible the missing cover will create another problem. Along with the (possibly) missing schematic, there could be some introduction of hum. I hope not. js

I found a clear, re-worked REK-O-Kut Challenger R-8A schematic this site http://kjq.us.com/rekokut.html
There's also a link to a person who rebuilds cutting heads.
