FS: Ramsey AM-25 AM Transmitter, Needs Repair. I built this unit and and used it for a few years, then put it aside. The RF carrier seems to work ok, but audio is low level and distorted. I would guess that a transistor or two in the modulator section is bad.

Requires a 12V power supply, not included. This unit will perform much better if used with a standard linear 2-4 amp 12VDC supply, and not a wall wart or switching type supply. Includes a power connector but no RCA cables.

Comes with a copy of the manual, but it does not include a schematic. Cosmetic and mechanical condition are good but it needs repair. $28 shipped by priority mail from 91505. Please claim here and PM me with your shipping address if you want it.
