Re: [Flexradio] Amp for the 1500
I've heard that often. Is there any test documentation available to back that assertion up?

Re: [Flexradio] Amp for the 1500
The issue is overdrive. I have a HLA300v that has plenty of gain and the F1500 is a good match at 5W. 300W at 160m, lower gain at 10m. They use 4 SD1446 75W transistors. PEP claims are double reality. New version has MRF455 60W bipolars. Clean to about 200W level with output filtering and protection. However with that much gain overdrive with other radios is not hard to do at all.

Re: [Flexradio] Amp for the 1500
One of the main problem with these amps are the UNregulated bias supply . The bias that sets the class of the amp will vary greatly when it is not regulated . . Also the amps are highly overrated as far as power output. A pig with lipstick is still a pig. These amps are junk and are not approved for amateur use and could not pass requirements . Tokyo High Powers small amp is fine , Look for an old Yeasu FL-110 it is a fine amp or wait for Elecraft to relese their 100 watt amp .

Re: [Flexradio] Amp for the 1500
Viewed mine on a spec analyzer and it looks better than 99% of the tube amps available to the ham market today... I think most of the people that are commenting negatively have never actually owned one and tested it. Common problem. Dr. William J.
