Yes, the protection from HT makes sense. The trimmer adj. are by way of hex nuts not screw slots, and the tool i use for these is a length of stiff plastic tube that has been softened at the end with a heat gun and molded over the nut, so insulation from HT and effect of metal eliminatsd.
For slotted screws i use strip of fiberglass PCB filed to shape, with copper removed of course.
Signal generators are, ' Windsor mod. 66 a ' restored, and ' AVO MK 3'. Frequency counter is a' Leader' digital.
Amazingly, some of the tubes in this radio still have stickers on them stating they were tested ( by a radio shop ?) in 1938 and found good. They still seem to be good now!
