This amplifier uses the 3cx1500 tube. One is the flat blade type and other a twist lock plug. This amplifier is clean with only minimal signs of wear.
There a few minor nicks in the finish of black bezel around front amplifier. Henry 3002A vhf amplifier for 2 meters mhz this is the king of meter amps for terrestrial weak signal and EM work. I have listed this as local pick-up only.
During testing the grid current was kept under 100 ma and plate 1 ampere. Due to people swapping tubes the serial number of tube has been recorded. There are no dents in the case. Includes two copies of the operations manual and different power plugs.
The cw output power with 80 watts of drive is 1800. The tube is a nearly new, less than 100 hours use, old stock that makes full output.
On Sb with 100 watts of drive the output power is 2100 pep.
