The Henry 8K ultra is the heaviest duty amp of them all, no
others compare:
The amp weighs 350 lbs:
Plate voltage is 5800 volts unkeyed.~5500 Volts relay closed.
Plate
transformer rated 1 amp continous, 2 amp intermitent.
The control Head measure plate current, Plate volts, Grid current,
Filament voltage. 5000 watts forward power, 500 watts reflected power.
The amp is tuned remotely with the control head
which is pictured here, the rf/power supply can be used 100ft away from the amp.The cable supplied with this amp is only the
standard 20 ft control cable.
The amp covers almost all frequecies 1.8 to 30 mhz.
Tune up is easy and straight
forward, tune for max out put.
The amp uses a 3cx3000 A7 for the final tube. When you look in the amp, the components
are larger and heavier than any Amp I have ever seen, These are big components, BIG and HEAVY DUTY. 350 lbs worth.
DRIVE:
OUTPUT: Meter Coaxial Dymanic
100 w ~2000 Carrier about 200 W in = ~4000 Carrier more in more out.
Considerations:
ALL, I stress ALL components must be able to handle the output, even to a dummy load like I have done testing it.
Antenna
switches, coax, antenna, must be able to handle the power you plan to use>
Amp needs a 230 volt source rated 50
amp minimum.
Conclusion:
The amp can run 24/7 at 1500 watts out put, The blower is loud, but since it is remote,
I can't hear it, but have heard some Dentrons almost as loud>
Why buy an amp that can run much power than you can
use ? Why have an amp that is capable of being used for commercial needs ?
Don't buy it to run all the power, but if
you have to have the best, than there is no finer amp ever made or that even come close.
