OLD amp help

[jetson]

hi all. trying to find a schem or very close to verify tube complement.

would like to get amp running again for a young navy man. (it was his granddads) any helpful comments greatly appreciated! thanks. jeff.

I don't recognize that model. Does it correspond to any of these Dano's?

so-far the closest i seem to find is the silver tone 1303.

this amp was made by danelectro and sold thru Montgomery-wards.
apx year 1947.

Boy that is an oldy!

You have the puzzle already put together!!! Take photo's every step of the way and label your connectors as you unsolder... for exp.
( label the Tag "A", I use blue painters tape, leave the wire exposed so you can test it later if needed.) Then on the clue sheet (A: the brown wire going to V1 Pin 4 note it goes under the blue wire but above the red wire) After you have gone down as far as you need to in order to restore it. Simply clean it and do a cap job and start at the last "Letter" and work to the backwards to the top. Leave the tubes out, form the caps and test for voltages and when ready add tubes and fire it up. If you take your time and stay patient you'll be just fine. if you get tired take a break no need to make a mistake. it's always better to double check yourself and when in doubt replace the part.

It looks really cool I'm sure the Young Navy Guy will be Stoked to get it back!

best of luck!

Yes nothing worse than coming back to an amp you have been away from for a while and not being able to remember what went where.

Good note taking and labeling the wires and components go a long way to ensure you get it back together right.

If you are able, it would be good to draw a layout or schematic of the circuit as well.

A schematic has to exist somewhere, you just have to be diligent in your search.
Sometimes you may have to pay a few bucks for it but it would be worth it in the long run.

Very cool amp!

After looking at the pictures, I have a few guesses.

First, I think the 5139 stamp on the speaker frame is the date stamp: 39th week of 1951. That also puts it in the right date range for the tube selection, as most manufacturers had phased out plate-cap tubes by 1950 or so.

After studying the gut shot, I think the socket next to the 6L6 wants the same--two 6L6s wired in parallel. They appear to share the same cathode resistor. Pin four of the tubes are also tied together.

That means the remaining empty socket is the rectifier, though I can't see that socket clearly enough to tell how it's wired. In 1951, a designer would have had a pretty long list of recto choices--many with different pinouts.

You might measure the voltage on the heater of the rectifier socket. Rectifiers didn't always use 5 volt heaters. Might have been 6v for example, and then you'd be looking for a 6?? tube number (like 6X4 for example).

working from 2 schems now that both have parts of this amp as is.
tubes should be:
V1-12SJ7
V2-12SN7
V3-7C7
V4,5-6L6GA
V6-5U4

the schems are for the silvertone models 1344 and1303.
the amp has the input scetion of the 1344 in front of the output scetion of the 1303. both amps were made by danelectro for sears and robuk.

theres only 3 filter caps 1 duel 8MFD and 1 16 MFD.
death cap is .05 in both. trying to find it now. just remove right?
the new power cord will take care of grnd.

the field coil spks seem to be ok the only way to know is to light them up.

[Structo]

At least it has a power transformer.

A lot of those old amps ran on straight wall voltage.
