Get a large old TV power transformer. Use the high voltage to feed the 6146
and the 115 volt winding or filament windings to match to the amplifier
output.
You can use a 4500 ohm resistor of 20 watts across the highvoltage winding
and look at it with a scope. Select the winding on the TV xfmr and the amp
output tap that gives the best waveform with a 2 tone or 1000kc signal thru
the amp.
Other wise find an old tube amp with 30 watts or better output and remove
the output transformer.
Hook it reversed from the amp output to the 6146.
I've used both systems will good results.
Healthfully yours,
