[Boatanchors] DX 100

[Joe Dube]

I need a bit more help with the DX 100. Can anyone out there give me an idea of what might be the problem with my DX100 slowly falling Grid current.  This happens after I peak the grid current to about 5 mils  and then key the transmitter. It will hold for a few moments and then begin to fall to zero. At this point the plate current goes all the up to the end stop and I have to shut the plate switch off quickly.  This happens with a crystal as well as the VFO.  I changed the 20 mfd caps in the 6al5 circuit which supplies grid voltage.  I am at the end of my rope with thing.  I think I have tried almost everything. Any ideas will be appriciated.
