The guy in the video is wrong about the dates.
It may be late '50s or early '60s
Certainly not ;40s or early '50s.

Thanks Poynton for the historical time precision of this microphone preamp.

This is an RCA microphone amplifier produced in the 60s . It is mentioned in the 1967 RCA catalog ( page 65 ) .
The device is very impressive ! Price too ...It is necessary to buy from a pension😀
I used to have a vintage Gates germanium remote mic pre, which is in a small handheld chassis with a VU meter. Transistor is socketed, and I remember it is RCA. I got that for about $100-$200 on Ebay, but it actually sounds pretty good.
I also have a chances to use Chandler Germanium pre, which is really good for electric guitars. My impression with germanium preamps is they are more like in your face, and has flat (not 3D) presentation, which make it good for mono closed mic applications. Good for vocals, too. I wonder how it would sound when germanium is used in 2 channel amp to playback music.
I was trying to find the pictures of Gates pre, but I could not. Instead, I have found the pictures of Westerex germanium preamps, which were used for film mag recorders in 60's. I got them from a post production studio in London, and they say those are used for 2001 Space Odyssey. I just took out the transformers to use for something else, so I don't know how they would sound unfortunately. Transistors are 2G309.

And what prevents you from trying it yourself ? 🙂.... I now have 3 germanium phonos . And with the 3-dimensional sound they have everything in order . The sound is not flat at all . Very deep and dynamic . And a good stereo panorama .
Good to hear that! It should be depend on the circuit, I guess. We usually tend to push hard when to use those mic pres.
Not easy schematic to find so good luck!
