I have the Yaesu model FL-2100B 10-80 meter amplifier. I bought this along with some other ham gear a while back and finally tested it today. It does seem to have the proper voltages and both fans work and the tubes light up but I was not able to get good output at all. I tested it using about 70 watts of drive and keyed the relay but the output stayed the same. So either I am not doing it correctly or possibly it needs new tubes. The ones in it are Cetron tubes, 572B. Selling as is for parts or restoration. Please see all photos for condition. No returns. High buyer to pay $55 shipping. I will ship the tubes in a separate box.
