HA1 Keyer Success!

[Rinkie & Ron Pollack]

Thanks to all who responded to my query on the sidetone on the HA1 keyer.
Several people told me that the voltage across the bulb should be about 90V.
When I measured, there was none!  Although the 2.7 meg resistor measured ok
in the circuit, when I put the proper resistance across it (courtesy of my
1958 Heathkit Res sub box!), the bulb lit and sidetone sidetoned.  Replaced
the resistor, and all is well.  It's a nice addition to the
AT1/HQ170/VF1/Matchbox 1950s station that I use frequently!

Thanks to all who took the time!
