Sorry, Chas. No photos of the beacon. It ran a pair of 6146s loafing along at 50 watts. I do have a circuit somewhere. I'll see if I can dig it out and post that here.
Hi Chas.
As I said above, I have no photos of the beacon, but the contemporaneous documentation I made at the time I built it throws up the circuit attached here.
A thing of beauty, Roger. It should be hanging in the Louvre.
Those neutralising capacitor thingies must have been twitchy to adjust. I'm also pleased to see you used 0.01uF bypass capacitors. None of that 10nF rubbish!
TNX,
