Help with a Lear ADF-12E schematic

8/10/2004 10:56:18 PMBow

Hey all,

I just acquired a Lear ADF-12E aircraft radio.
It has 4 tubes in it:

VT1: 12BA6

VT2: 12AU7

VT3: 12BA6

VT4: 12BF6
It tunes 190 kHz thru 1750 kHz.
I would like to use it for DX’ing NDB’s and maybe listening to AM BCB… just because!

Would anyone happen to know where I could get any information on this puppy?

It is in pretty good shape too!

The Model # is: 2303A

The Schematic # is: 707944 J

If anyone can help, that would be great. I an currently cruising the Internet, but no real luck yet.

I never worked on Lear, but I am familiar with ADFs. I will help if I can. Hook the sense antenna up to a long wire, you can have lots of fun DXing at night. Some NDBs give weather.
