Hi.
The shortwave TX test project has now been dismantled and the board will be used as the timebase panel with video output and sync. I will be mounting this on an alloy box chassis underneath. the Line and Frame output transformers will be mounted above the chassis along with the power supply items. I intend to run this with the two DC to DC I used on the TX project certainly initially.
Once the timebases and video section has been tested and found to be satisfactory or other I will then decide to either make an RF stage or not. If this initial work is good then I will need to decide whether I should go the route of a TRF or Superhet, again using rod pentodes.
May start next week.
