Briggie, I just got to tell you that I cut my radio servicing teeth on these radios at the grand old age of 11 my mentor was what was regarded as the best rig doctor in the business back in the 70s and 80s handle was "professor" Im chuckling as it was my job to connect up the pll and align these when they landed in crate loads via Belgium.
Tell you what tho this chassis stalker9, stag 357, wks 100, etc IS the best chassis and the components used were top quality, DO NOT SELL YOUR STALKER even if they are going to cut your electric off lol.
Sadly, Lou (professor)passed away in december 09, I lost a true friend and my mentor and miss him dearly, 35 yrs after our first meeting I still have a "tweaked K40" that we designed together and had so many contacts on.
By the way I have r.i.t on my stag, have never seen any others been done only 2, mine and Lou,s and variable power output and a 7.5kc plus and minus, god this brings back memories
