wrote: I am curious about this precision 910 tester. I have a 612 which is not unlike this, but it has 10 lever switches to select the connections of the 10 tube terminals. On this photo of the 910 there is just a row of buttons. Anyone know how the three choices [common, 'plate' and filament] of element connection are selected in this model?? Thanks Neil S. Way too long ago for me, but I remember punching those buttons a lot. bg I think the grid, filament plate are all controlled by the rotary switches, iirc. |
