Sams folder 722-5 covers it. I don't have it, and it's still in copyright, so it won't be on the web. $8.95 from here: https://theschematicman.com/hardcopys.htm

Thank you, a service is definately in order. I know a guy, so my lack of ability wont hurt me there.
I love AK and have read so much here, albeit much of it over my head, I am trying to learn. Tinkering is a loose term... i can hook anything up and have a decent understanding of how it works, but I still should stay out from under the hood.. so I know my limitations.
This amps input is not phono. My turntable has line or phono input, only line works so I have to assume the input has a preamp integrated.
Thanks for the response!

FYI, you call it an amp but in reality it is what's known as a receiver. A receiver has basically 3 main components to being a receiver.
1) It has a tuner.
2) It has an internal preamplifier with volume and tone controls.
3) It contains a main amplifier output circuit. In this case, the 6BM8 or 6BQ5 tubes.
In my humble opinion, this is not a good candidate for any stand alone use. Nothing really special as it is low wattage on the output side.
Personally, I would refurbish it as a whole. The speakers are matched to it. Plus, if you were to do a total recap, you might be surprised of the sound this little thing puts out.
Do as you wish and have fun doing so.

Your turntable has a built in preamp so you would always want to have it set to "line" when plugging into the phono input of this receiver. The turntable in this console most likely has a ceramic cartridge so the phono input on this receiver acts like a line level input (CD player, tape deck etc.) so aside from any parts being out of spec or needing to be replaced, it would normally be pretty loud if you were to use a CD player, phone, or other some external source in the phono inputs.
Your picture shows the chassis as being dull yellow ,if it is so you might have a cadmium-plated chassis that has oxidized .
Cadmiumoxide is toxid be carefull while cleaning it , take safety precautions . Work outside, if possible , wear gloves and dustmask .
More info on the web .
Take care and be safe.

All this information is so great, I really appreciate it. So I have a new idea for this but I want to see what you guys think.
I have a great sounding solid state system, but I am a sucker for the warmth of tubes. Is it possible to use the RCA style "external speaker out' as a pre out if I had a speaker to line level converter, then run it into an input on my solid state amp. Essentially make it just a tube pre stage? I may be way off base but it seems logical to me. Should add a little tube warmth to my solid state system.
Next question... is there a trustworthy place on the internet where I can send the receiver in to be checked out and repaired if need be. I am no where close to having the skill or understanding.

I got this thing hooked up to my Daytons and man does it sound sweet. I ran a bluetooth adapter into the phono input and it works but the signal is much less than the actual radio signal, so the radio is nice and loud, but the bluetooth is quiet. Is there a way to boost the signal going into the phono input to bring it up to the level of the radio?

Me likes the eargasm retroplasm...
Make sure that the volume on your phone/mp3 (whatever you are sending the Bluetooth signal from) is up. ...or since you now have two sources that seem quiet, then this might be evidence that there is something wrong in the preamp stage.
Chances are, the RCA style "external speaker outs" are not pre-outs. I might be wrong though, and you might experience the so called "tube warmth" that folks speak of...
Tell us what your closest metropolitan city is, and some might know of an electronics repair nearby you.

The phone is all the way up... but good point, the turntable is quiet also, so you are probably right about the preamp stage.Make sure that the volume on your phone/mp3 (whatever you are sending the Bluetooth signal from) is up. ...or since you now have two sources that seem quiet, then this might be evidence that there is something wrong in the preamp stage.

The external speaker outs are probably just that, not a pre out, thats why I asked about the Line level converter.
I am an hour from St. Louis Missouri.
Thank you!

The Devil made me do it.
No there isn't, you would have to send it to an actual place with a physical location.

I have determined there is no schematics or information for this amp. Chassis 9066 is not a thing on the internet. Airline 9066 doesnt exist. Montgomery Ward 9066 doesnt exist. Valco 9066 doesnt exist. Wells-Gardner 9066 doesnt exist. How is this possible. I cannot even find a different receiver that looks similar. So frustrating.
The amp sounds awesome, I can only imagine how it would sound serviced. Apparently its impossible.

Any chance that Arvin might have built it? They built some store brand items in the era.

I think you have to go by the Model number (as given at the top left of the tube layout sheet shown above) not the chassis number to find the Sams folder. Tom Bavis identified this above for you as Sams folder 722-5. This should have schematics and data.
