i've owned this unit for almost 10 years now. it came from CA and was built by Jack Gittings. I'm guessing it was intended for carrier current. the transmitter is all homebuilt in a commercial aluminum enclusure. it uses a PLL unit shielded in an altoids tin. audio is provided via a car audio chip amp driving a large hammond transformer into a 6AQ5 tube. it came to me with an LPB carrier current tuner.
does anyone have any info on these or own a similar unit?
i need help with retuning the TX output to a new freq. i did figure out the switches on the PLL based on trial and error with the tube pulled and a freq counter inline. i'm just not confident in retuning the tube output section. this thing is so rare, i dont want to burn something up. the freq i used to use in a different location is in use in my current location so i need to move. audio on this thing is simply amazing.
