Title: Lettine 130 transmitter Post by: n4joy on February 13, 2020, 08:51:06 PM Thanks to W3JN and WA4BWO, a Lettine 130 has been added to my Lettine family! This model is a rare bird indeed as there is almost no information on it outside some QST ads. Tube compliment is 807s for the oscillator, finals, speech amp, phase inverter, and modulator; two 866 rectifiers; and 6L6 clamper. The QST ad indicates 120 to 130 watts input.
I will post more photos as the cleanup progresses. Title: Re: Lettine 130 transmitter Post by: n4joy on February 13, 2020, 08:54:37 PM More photos...

Title: Re: Lettine 130 transmitter Post by: w3kbs on February 18, 2020, 06:53:34 PM Nice Lettine 130.
Have been looking for one for a while or even a 240. I just finished the 6 meter 242 Transmitter and it really does a nice job on 6AM. Put together pretty well for the time period. Gud luck with her. w3kbs Title: Re: Lettine 130 transmitter Post by: n4joy on February 19, 2020, 07:23:33 AM Nice Lettine 130. Have been looking for one for a while or even a 240.

The 130 is quite rare and maybe as rare as the 262. I have amassed a somewhat large collection of Lettines and enjoy restoring and using them. Information on them is virtually nonexistent outside the old QST ads. My first was a 242 that I use for a local "net" on 50.4 (Sunday at 7 pm EST). Lettine also made a VFO and tuner. I built the VFO unit from scratch (pics posted here) using the schematics. On a related note, the 240 schematic on Bama is NOT correct, so I will see about posting my scan of an original. Title: Re: Lettine 130 transmitter Post by: n4joy on March 20, 2020, 10:58:05 PM I completed the work on my Lettine 130, which included all capacitors and resistors replaced, wiring cleaned up from previous maintenance, new rectifier tubes, and two fresh 807 finals. I also had to replace the AM/CW switch.
All works as it should! Output is over 70 watts on 40 meters. Title: Re: Lettine 130 transmitter Post by: w3jn on April 02, 2020, 04:14:55 PM Glad you got it working, and happy it went to someone who really enjoys it. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
Sorry that toob got busted in shipping, I thought I stuffed enough paper in the thing to keep that from happening. |
