Dearmond Rhythm Chief 1100

[belwar]

I'm dreaming one day of making an archtop (I even have the wood ready to go) and would love to know the specs for the Rhythm Chief. Would it be too much to ask for some photos and/or readings, wire guage etc.?

How could I say no to someone from Victoria?! I grew up there! I sure miss haultain fish n chips.. Though its not as good as it used to be. I recently had fish and chips last time I was in vic at a place next to Art's Bakery.. I just cant remember the name. I've spend the last year trying to duplicate thier batter.. I think i've got it now.

I'll snap some pics for you later and post them in the above thread.

DeArmond Vol. Tone Module.

What is the schematic diagram of the inner workings of the 1100 and 1000 control modules on the DeArmonds. What is hooked up to the the switch and directly to the output . RE: the 0015 and 047, where are they connected, exactly. I am using a spdt mini toggle, what goes where? What is directly connected to the volume, what is the switch adding? I know .047, .0015, which goes where, switched, direct. Hot goes to? Can anyone explain the complete schematics?...Thanks MS64RED from eBay.

pot values

Hi,
I am rebuilding a rhythm chief control box and am in the same position as you but do not know which pot is volume and which is the tone. From the picture that have already been kindly posted I can work out the rest. Does anyone know which is which?

Cheers

I'm going to take a wild guess and say that the one at the top with the tone cap soldered to it is the tone pot.

Tone pot value

The one with the tone pot cap soldered to it is indeed the tone pot. I was wondering what the value is. I have a 1M pot not exactly Linear or Log and a 250K pot not exactly Linear or Log. Which is tone and which is volume?

Does anyone know the value of a Rhythm Chief Volume pot.
Thanks

Back to the winding method, don't forget that hand winding was common in large factories in the earlier years, I repaired a monkey on a stick pickup a long time ago and the wind in it was very sloppy, not machine looking at all. I'm not sure when the 1100 was manufactured, somewhere I think I have the patent, or actually it may one of the ones I could never find. The closest patent is for the mandolin version. I think there is also an 1100 pole piece version thats later.

BTW here is video from my pickup factory, I have a VERY strict dress code:

Below is a photo taken by one of my spies of girls winding at Jon's garage :-)

The Rowe made DeArmonds were wound on Leesona 102's. I have the Leesona serial number records from 1959 on, and the second page of serial numbers has the first of many Leesona 102's for Rowe. Im working on getting the serial number records prior to 59.

At 1:08 you can see Dave inspecting the winders.

We' re making pickups with 2 gauge wire, they sound very hi-fi

tone pot volume pot values

Does anybody know anything about the values of either the Tone pot or the volume pot of the Rhythm Chief control box?

Thanks

[David Schwab]

I seem to remember the volume pot being 1Meg.

Thanks

Hi David,
Thanks for that. That's what I was guessing but needed a bit of confirmation before I assemble it all according to the photos. I'll post the circuit after it all works satisfactorily.
Cheers
