Hi Dave, Thanks for the report. You might want to try a new tube for the
high 1st osc, also.
I have a 15.5 crystal that is 1.1 kc high that I would sell you for $10 +
shipping.
On the one I'm working on, I have finished sanding and priming all the
black work and painted most of it. The meters, readout cover, and large
black knobs turned out very good. I've replaced all the mini coax in the
RF deck - oh what fun.
Regards, Larry
