Yes, Meshna is where I got three boards from in 1979 and later on my seven NOS tubes. By 1980, the prices had almost doubled (used tubes were USD$4 and NOS were USD$5) which is understandable considering the massive inflation in the 1970's. I do not recall what I paid for the 3 boards in 1979. Definitely needed the HV transistors from those boards. I still have one complete ticker board left with sockets but without the tubes. The clock schematic provided by (I think) Poly Paks, that I built, had several serious flaws. Most notable was they used the wrong transistors for the anodes. Each board had two anode transistors (the two transistors on the far right in the picture) and the other 30 were cathode transistors. They mislabeled the transistors on the schematic indicating to use the cathode transistors for the anodes. When I discovered the error, because my clock did not work, I changed them out. I needed three boards to supply the six anode transistors for my clock. As I already had a board purchased earlier, I was able to keep one complete board as a spare.
