My old Hammarlund needed some maintenance, and I took the opportunity to 1) get familiar with the Q Multiplier, 2) move the BFO switch to the front panel, and 3) get ready to put in a better (grounded) power cord and a fuse.
D-Lab provided the idea on putting the BFO switch in the hole meant for the clock control: https://www.youtube.com/watch?v=zSL3mSAoC-o
I picked this old receiver up in the Dominican Republic in 1993 or 1994. It had been owned by Antonio Gomez S. HI3AGS in Santiago, DR. It may also have been owned (or worked on) by a Rafael Inda (his name is scratched onto the inside of the chassis).
