I just did the modification to put my L7 on 10 meters. Works like a champ.
I now need to retune the tuned input circuit for 15 meters. There is a step
by step process in the manual that states how to do this. It says to
"remove all the jumpers from the 7 terminal barrier strip in the PS."  This
is so the relays, fan, filaments, etc. will  work without the HV being on
(so I can dip the PLATE etc. to retune the input coils).  Well there are 2
jumpers on this barrier strip in the PS and when I remove them and follow
the procedures, I get nothing. No filament or relay power whatever. I read
through the steps a zillion times whilst banging my bonehead agin the wall.
All to no avail. I think there's something I must be missing with step "c"
in the op manual section 5-10 which is what is in " " above.

Any L7 owners can shead some light on this?

What the flip, OVER.

Thanks,
Matt--K7BG (being extra, extra careful)
