    Just purchased a Knight RF Generator on ebay and got the same scope a couple months ago. Great video for me, thanks and subscribed.

    What does the wave look like if you use a properly compensated scope probe? Nice video.

      +TheRadiogeek Thanks. It looks pretty much the same (i.e. similar weirdness on bands A-D). If one connects a scope probe directly and omits the 50 ohm terminator, the vPP is much higher, as much as 4 Vpp. nselabs reported similar odd waveforms on the lower bands and added a pot between the two stages of the 12AT7 to clear it up. I haven't tried that myself; my worry is that it would clear up the lower bands, but significantly reduce the output of band E.

    Was working on the same generator. It had poor sine waves until I cleaned the wafer switch with Deoxid.

    How can you test, or how do you know if the selenium rectifier is bad?

      jawspinkid if its selenium its bad. They go bad just over time.
