Happy Sunday everyone,
An interesting power amplifier just popped out of the "time closet".
It is an AM-912/TRC with a frequency range of 100-225 MC; love those
old units! :-)
The amp utilizes a 4X150, which is operated at 750 volts, to output
all of 100 watts. The construction is excellent with identical
crank-knob tuned silver plated cavities on both the grid & plate.
Does anyone have any experience with this unit?
Specifically with updating it to a more modern tube and upping the
plate voltage?
& what is the best tube that would fit the foot print? The 8930 is
not an option due to the existing plate collet. What about a
4CX350FJ/8904 or does that suffer too much above 100 MHz?
Thanks in advance for any info!
73,
Marv WC6W
