Can you identify these old Tube amps?

[decooney]

The smaller unit (or amp) actually produced audible sound. I hooked a CD player up to it through the RCA jacks many years ago and a nice sound came out of the speakers for a bit then I shut it off fearing it needs to be cleaned and checked out... didn't want to damage anything. Has a lot of dust on the tubes and all. The knob to the right is a volume knob 1-10 on the smaller unit.

If it produces nice sound, then turn it up a bit and see if it produces nice sound. If it does, its probably working fine as it is.

Still wish I knew what each of these units were originally made for and used for, originally?

So far we have responses here on the Ampgarage forum indicating "amplifier, converter, H.A.M radio components, FM tuner" and more. I have no clue. Hopefully if someone can specifically identify the function of each and how/if they relate to each other somehow, that would be a great start. I might end up parting with these to someone who can make use of them somehow vs. them getting parted out or me just storing them. If I could confirm these units are for H.A.M radio use somehow, I plan to contact some of the ham folks next to see what they can figure out.

I'd advise carefully exploring the Dynaco connection a bit more.
These may very well be early prototypes or "kit-bashed" (modified kit) early models.
The absence of any control panel markings, labels or other identifying marks suggests something of a one-off nature.

As have been said - the filter cans strongly indicate something "radio" like...
getting the frequencies off those x-tals may reveal something..... or not...

I received notification from a gentlemen this morning that told me these two units are a vintage Tube R.F Tuner & Tube Audio Amplifier (1950s), most likely a self built kit of sorts. He told me not to try and make a Dynaco connection for these units. I've received multiple unsolicited replies offering "help" trying to tell me what they are not. I will pull them back out of storage after the 1st of the year to look at the crystals and #s.
I sort of want to leave these untouched and into the hands of a pro collector who knows how to service these units, restore, ensure operation.

QUESTION:
Would anyone here happen to know IF Dynaco produced kits for both radio tuners and amps in the late 50s or early 60s, if so maybe I can find some photos out there to see if there is anything that might look physically comparable to these units. In the rare chance they are some sort of Dynaco kit pieces, I'm thinking I'd like to see them go to an avid Dynaco collector who collects these kinds of things.

Update: Almost done researching. I think I've found enough information now that leads me to believe this is radio communications equipment of some kind, most likely self-built or prototype gear. i.e. Not Dynaco, but some of the parts may have been sourced from the same parts houses in Philadelphia at the time. Maybe this is why the chassis and top looks remotely similar to other old pieces of Heathkit or Dynaco gear. Similar but different as I understand it more so today than yesterday.

To recap, this old gear belonged to my Grandfather. I found today that he was listed at one time as being the Chief Engineer at H&R "The Herbach and Rademan Company" in Philadelphia. H&R apparently made and sold parts for all sorts of communications, radio, tuner, transmitter, amplifier, and radiation detection equipment. This could be why the pieces look sort of familiar but not exact to others.. I also found a patent under his name for radiation meters and he later worked at AEL and AEL-Emtech which developed this kind of stuff for D.O.D. This now explains all the junk in the basement that nobody understood back then but him. I've reached out to the ARRL / QST magazine group who will have more information. He was the ARRL Eastern region manager there for Pennsylvania with all sorts of references to him in QST magazine. I found one QST article reference he wrote titled ""Ultra Midget Equipment for Ultra High Frequencies". I guess he was more than just into H.A.M radios...

Thanks for everyone's time here. Off to see the Hammer guys now.
