Hello,

 

Thanks for all who replied with useful info. 

I got the unit lined up.

 

I was puzzled as I prepared the L7 on a separate table with my TR7 into a
dummy load (with cabinet removed).

After all was finished I installed the cover and placed it into the
"operational position" next to my MN2700 and Elecraft K3.

When tuning I found a bad input SWR (1:3). So I decided to tune the input
circuit as I read that it might be necessary after a tube exchange (other
manufacturer).

When all was disassembled, the top cover removed and placed on the test
bench, all worked fine again.

 

I found out, by accident that the front left screw which fixes the cover was
touching the left-under bar (fixed plates) of the load capacitor (which is
hot). I replaced the screw and all is fine now.

 

73's, Evert PA2KW
