  I understood that the 'B' set had to be decomissioned before they could have been sold as surplus. Looking at adverts in old magazines shows this too. I was told this by the late & legendary Nev Kirk, G3JDK. The B set was what they called UHF back then & this set covered 229Mhz to 241Mhz, which as you know isn't an amateur band in the UK.

  Did you move the GU50s around to different sockets to see if the red glow traveled with the valve or if any GU50 in that socket glows red? That's the first troubleshooting step, to make sure there isn't a problem with that socket or that channel's wiring. ;)

  Where do you get this crap? This uses AM modulation onto a pentode grid. Will need to set 50% power with negative bias on 3 grid then it works cleanly.

  @thewtf10 күн бұрын

  Thats more or less how it works… suppressor grid modulation; not very efficient!

  Could something like this be achieved with larger ceramic piezo transducers? I found some of them working at around 2Mhz. I see here you're using 8.2Mhz... I'm curious to try this concept on something larger like a garden hose

  I'm pleased to see how you've set the horizontal and vertical scan amplitudes (a reasonable compromise for the screen shape). But back in the day, sets were always set to overscan - no black visible at all - which always irritated me, as I'd rather have a (slightly) smaller picture but at least see all of it!

  Why does this TRF have so much crackly noise? If the noise source is the antenna or local switching device radiation, can one or more broadband filters be strategically installed to eliminate this noise?

  "Old men talking crap..." Yes, heard on 160, "Jimmy put up a tower a few years ago and he only put a guy wire on the east side because the prevailing wind was always from the east. Well, it stayed up for a couple of days, but then one day the wind changed coming in from the west..." And other tall tales.

  To this day my favorite aircraft. Probably because my first flight ever was in the mid 1970s on a DL L1011, JFK-FLL. Huge, wide cabin, friendly employees from start to finish, and they served us a steak dinner in coach. It was magic.

  I love this old tech. I have a 5C/450A which is similar but even larger. I haven't tested it, I must one day. I also have a beautiful 4212E triode, but sadly when I tested it, it had very low emission.

  Way back in about 1970 I used the cabinet and the CRT from one of these to make an oscilloscope using a circuit from Practical Television. I stripped the scope down about 2006 and I still have the CRT. I may still have the motorised unit somewhere in my junk. I looked inside and it was some sort of rotary switch by the look of it. Amazing to see it again after all those years.
