[Boatanchors] Fw: DX-100 RF delay

[Bob]

I have been out this morning and just got back. Thanks for all the replys. I 
now have some checking to do. I had previously replaced all of the tubes 
with ones that all checked good on my Heathkit TC-3 tube checker but I will 
do it again with known good tubes ( I have another good running DX-100 and 
will pull those and use them in this set). I will also check back the grid 
voltages for delays starting with the 6146's and try all of the suggestions. 
As I don't have a lot of time to work on it it may take awhile. Thanks again 
and I will post the fix when and IF I find it. Actually it doesn't seem that 
it should be too hard to find. Where have I heard that before?
