Telex part # 04369 matching transformer

[rabbiporkchop]

I have piles of Electro-Voice microphones that need this matching transformer. Has anyone found a suitable replacement with a 4:1 impedance ratio since Telex sold Turner?
The new manufacturer of the Chinese built Road King 56 refuses to sell parts. Here Is the transformer:

Here are a couple of the Microphones I am trying to impedance-match:

What are the actual impedances you are trying to match? 50-200 ohms? 150 -600 ohms?

 

[rabbiporkchop]

150 -600 ohms

150 ohm element to 600 ohm input.
No luck with anything from Mauser

You beat me too it. i did a Google search and was working my way down the page from Hammond to Digikey and was looking at Surplus Sales and thought "AH-HAA That is what he needs" then I came here to spread the good news but you beat me too it. LOL.

I did some research and the manufacturer told me to call Rockwell Collins for technical information.

All the guys that do direct injection especially if they are using something like Motor Mouth Maul or Asymod use 4:1 transformers. Anytime they start adding studio gear that was just not intended to be feeding a CB radio they get issues. I can not think of the guys handle now but his logo has a donkey and two hammers and I think it is something like "No Name" or "Stick Man"???

Finding an audio Transformer with a 1:2 winding ratio and a 1:4 impedance ratio is kind of tricky nowadays especially when you're trying to match 150 ohm cartridge to a 600 ohm input on a radio
