Am looking for any info and a schematic for a Simplex Cathedral from the 1930's. Round dial, 2 band superhet. Farm radio, runs on 135v and 2v. No model number on the unit. Uses 5 tubes: 1C6, 33, 34, and 2 x 30's.

There are only three chassis listed in the grilleclothe.com search engine that match that tube lineup. None of them are by Simplex. Two of them are listed in Riders. The third -- chassis AW by Radio Chassis, Inc. -- is not.

Allied Radio (Knight) models G9561, G9563, G9565 and G9567 below serial number 61700

Radio Circular model ACE 5 Tube Dual
:arrow: http://www.nostalgiaair.org/PagesByModel/038/M0016038.pdf

Both of the above use the same schematic, so they were probably made by the same manufacturer.

(BTW, did you post this question earlier only to have it vanish? I was going to post the above reply about twelve hours ago at about 1:45 a.m. But when I went back to the post, which I had kept open in a separate window, it had vanished and had been replaced with the message "This post does not exist." I've never seen a post vanish like that from these forums before.)

Thanks so much for the reply! You really hit the nail on the head. It is an ACE model 956x, early version. Actually was made by Allied Radio. Not sure why the Simplex name plate is on it. It is a farm radio, strictly runs on batteries (3 x 45 B batts and 2 volt A, probably wet cell, or "air cell" whatever that is. Send me a regular email and I will send you pictures if you want. jameswross@earthlink.net

Yes, both my post from last night AND my entire account vanished. I had to re register today! I informed the moderator.

73,

Jim

Since this was made by Allied Radio in the 1930's, I think this might be an early KNIGHT-KIT, based on the amateurish construction techniques. If so it would be very rare. Few early Knight Kits survive today.

.

'Simplex' (of Sandusky Ohio) was a manufacturer whose products were occasionally rebranded. 'Allied' was a retailer that operated a large mail order business that often sold items rebranded with their own name or product-line name.

Spending some time digging through the Allied catalog archives might produce a listing for this model if it was sold through Allied.

This site has most all of the Allied catalogs.

Anyone working on this radio should note there is a voltage dropping resistor from A- to ground shown on the schematic. The radio was designed to work with a wet zinc-carbon-lye-oxygen "air cell" which initially puts out 2.8 volts, for 1000 hours without recharging. It uses 2 sacrificial zinc anodes. (Cool technology for the time, isn't it?) :wink:

Think of it as 2 big D cells in series.

Anyway, if you use a 2 volt storage battery A supply you need to bypass this resistor on the end of the Candohm, or else the A supply will be only 1.3 volts to the 2 volt tubes, not enough to operate them!

Also, the B+ supply is not switched, so be sure to disconnect the battery when not in use!

As soon as I saw that dial, I knew I had something similar!

This chassis has been kicking around my storage loft for years. It has "Model 6GM" stamped in ink on the back.
A http://www.grillecloth.com search comes up Zephyr Radio Corp. Though, the tube lineup also falls under Pacific Radio Corp. for the Aetna, Knight and Manchester trade name. Model 6320 or 37-6320.
The tube lineup on this one is 6A8, 6K7, 6H6, 6F5, 6F6 and 5Z4

The schematics are different, so I don't know the exact details of manufacture, but the dial assembly has the same identical construction as your Simplex.

If you click on these links you will see there are 3 tube lineups, and not entirely like yours:
This is from the thread above:

There are only three chassis listed in the grilleclothe.com search engine that match that tube lineup. None of them are by Simplex. Two of them are listed in Riders. The third -- chassis AW by Radio Chassis, Inc. -- is not.

Allied Radio (Knight) models G9561, G9563, G9565 and G9567 below serial number 61700

PS: let me know if you want to sell your dial

Well, my dial is different as it has an extra band, but I will be willing to sell the entire chassis. $20 + Shipping

Fix it up and put it in your cabinet and you will have an AC model ready to plug in the wall and play.

Nope, unfortunately, what you see is all there is of it. I have no idea where it came from, but I've had it for many years. It looks complete other than tubes. It definitely was made for metal tubes.

-Steve

EDIT: OK, how about $25 plus ship with a complete set of tested good tubes? (Tested on my Jackson 648-1T)

If there is no interest, I'll put the tubes away and put it back in storage.

I apologize if I was asking too much.

Steve, no apology needed

The dial was not really correct for the set.
I was looking for a similar dial that had the top numbers not faded out.

Thanks for the offer!

Jim

Steve,
How about $15 to ship, you keep everything but the dial? (if you want)

Guys-can you move the buying/selling to PM's?
It's not permitted in this forum.
Thanks,Phil

Well, kinda late now anyway.
A friend came over this weekend for another reason. Saw the chassis as I had it out and he decided he wanted it.
