Your amplifiers have clean output - practically free of harmonics... I wish I knew where to buy the metal chassis.

[@TelstarElectronics]

Metal and plastic chassis are available from numerous places. I prefer the plastic... much easier to machine.

I still have your DX150 KIT...

Do these amplifiers work on other bands like 20, 40, and 80 meter bands?

[@TelstarElectronics]

The DX250 and DX300 will not work on those those bands because they have a tuned output.
