Hi, Jeff, I've been doing some reading on oscillator problems, and ran across a reference in Marcus and Levy about oscillators that work at higher frequencies but not lower. They say it is almost always the converter tube when that happens. So if you have a spare, it is worth trying that.

Here is the link to the book, "Elements of Radio Servicing" by Marcus and Levy, 1947

http://antiqueradios.com/archives/Elemen...h13-16.pdf Assuming you can open the file, read from the middle of page 244 where it says in bold print "Troubles Common to the Pentagrid Converter Tube".

You can download the whole book for free in 6 pdf files here: http://antiqueradios.com/archive.shtml
