Tsunami Project (4cx5000 series finale! ! ! ) 

Congratulations on your build! You’re definitely representing The OH-10 very well! 73 from Lorain 🎙️🎙️🎙️

Excellent video series and a great accomplishment. Congrats 🏆

Nice outcome, exactly what we expected and I think a little more. Thanks for all your hard work and help on this project, fantastic

Tony, congratulations! You got a great result on the 4cx5000 Tsunami project. I'm sure the 3 tube GI7B project will be easy for you.

I wish all amp builders would test their builds like this for spectrum purity. Very nice build.

Very nice amplifier and very good video

First class build Tony.

That a great amp ! That is why I only use tubes for QRO SSB . The IMD is much better ! Like the new screen supply using IGBT . We got them in a broadcast transmitter . used in a different way. Plate modulated supply for AM. The screen done same way . Big power saver. Continental AM transmitter. Stations like WBCQ and WMRI are using them. Great tube life . That IMD test will get even better with a bigger cap bank. You need a bigger dummy load. What kind of amps that drawing from the mains ? Great way to stay warm in the winter ! LOL 73

Great video! what are the 2 tone results with the Yaesu running by itself?
