Keyall HV+ with a Heathkit SB-200

A customer reported that he had trouble with his Keyall HV+ kit while trying to key a Heathkit SB-200 amp:

The SB-200 has a 6.3 VAC filament transformer which has a grounded center tap.  This means that there isn't enough DC voltage to overcome the red LED in the Keyall HV+ circuit.  One workable solution is to replace the LED with a short circuit which allows enough voltage for the 3.3 volt regulator to function.

I learn something new every day :)
