New informations.
I had been able to receive a response from a FL-50B owner. He told me
he no more has any manual, but the output power should be 30/40W.
Hovewer, his transmitter, bought used from a CB, never output more than 15W,
also after realignment and changing final tube.
Wherever the problem is, it seems to be a common problem. I promised to
told him how to fix it, if I'll ever be able to fix mine...

How should be the output impedance of the 6JS6C? I'm beginning to suspect
it's not correctly loaded...
