I use this TBW transmitter on 40 meters for AM (7.290) and have been opperating it for around four or five years now. The power supply is home built and located in both the old center section and under the rack the transmitter lives on. KA3EKH

  • The 800 cycle stuff was for use with the field generator set, being high frequency it only required small transformers and filters for the DC supply. I used all new componets for a 60 cycle supply but with the increased size for 60 cycles the power supplies and filters will no longer fit in just the center section. also you no longer have the ability to run A2 where they used raw AC applied to modulate the transmitter.

  • Wow!

  • I'm really curious to know, how does your homebrew power supply tackle the 800Hz frequency requirement of the TBW? Do you have a schematic, or construction details? I'm considering one of these, but really don't want to have a huge motor-generator set. Thanks!

  • very well done presentation! Looking at past eras of Ham Radio equipment and it's control operator they did indeed have a real sense of accomplishment. Historical

    radios and electronics is amazing, and advances in technology to present day. I'm a Ham since 2006, I did not go to HRO and buy a dual-band Icom, but bought gear on E-Bay i.e. power supplies, vintage Icom and Kenwood mobile radios plus two Motorola HT's I had programmed for 2-meter operation.

  • With those radios, you really felt like you were doing something,and when you finally got on the air, what a feeling of accomplishment! And also they were good for aroma therapy, the smell of those components in the heat was transendental.

    Thank you for this video, well done.

  • Final tube in the TBW is a type 803 which is an earlier and taller tube than the 813.

  • wow great video. they sure are easy now lol

  • cool :)

  • What will that put out. Is that a 813 in the

    Final tube?

  • Very well presented, Ray.  Nice setup.
