HRO-5 and Russian Pencil Valves

Hoping to fix my HRO today.... Clive M5CHH is coming over with his and will do a side by side comparison and fault finding to see what might be wrong.

In the meantime I am also looking to build an RX, TX or TRX for other ham band certainly 80m based on the 1b24b or 1sh24b tubes (aka Sputnik) and I am reviewing a few options. There are some great designs out there already  but I'd advise you start maybe here and for technical details of the valves. I especially like these. If you use Google chrome is can do a Japanese to English translation... bit off but readable.
