| Heading: | WRL UM-1 modulator |
| Ad Message: | For sale is a homebrew version of the WRL UM-1 modulator designed to plate moudulate a Globe Chief 90 and other transmitters. It at minimum needs a bias resistor which is broken for the 1885/6L6 modulators. The modulation transformer is a CVM-2 multi-impedance unit. I did not have success getting it going and modulating my Lyscon 600S though it seemed clean on the o'scope. This is a heavy best with all that iron so very hard to pack and safely ship. I am asking $50 for it picked up in SE Michigan. PayPal, USPS money order or cash is acceptible. |
