super ! now you may need a Byrd 10K load . full power test is a good way to check HV supply drop. great SSB HF radio. just lacking AM drive. my 7300 same way. AM drops way down like 25 watt peek . you are going to love the adjustable filters on the receive when the skip really gets going. 73's
Ab2 per the tube spec with 500mA of idle current. Most guys that only do AM and some sideband only set theirs at 250mA, but as a sideband operator I find that 500mA gives phenominal results with very low IMD.
Really impressive Tony !!
I know NB777 is smiling right now with anticipation !
Beautiful amp!! Love the extra mile u put into the decal work!! 😊👍🏻

Yeah these tube boxes have been fantastic. Gonna swing back to some new solid state amps and play around with those.

Nice looking amp 🙂
How do I get in contact to ask some questions about an ldmos box?

@@NeedleBender785 thanks for the replies! I only get 150ma on ssb with my 1200
Needle benders are mudducks! No such thing as rms in rf, geez
