I have acquired a Henry 2K Classic X (domestic model) amplifier. It uses a
pair of 3-500Z's with chimneys. The very loud Dayton blower is driving me nuts.
The Dayton blower is a model 2C915A, 3020 RPM, 230 volts and 140 CFM. This same
blower is used when the larger Plate transformer of the Export model is
installed. I suspect that this blower is much larger than required when
operating at 1500 watts on CW or SSB.
My other alternative is to install a smaller blower and risk shortening tube
life. I do not contest very much nor operate continuous modes such as RTTY and
FT8 at full power.
Your ideas are welcome!
Mount the existing blower in a plywood box behind you and run a hose
to the amplifier.
