No, the HP107 is from the transistor era, circa 1964. It is built
in a similar fashion to a Sulzer 2.5 oscillator.
My problem is not knowing what is in the areas I cannot view, I don't
know when I should be unsoldering wires, and when I should just pull and
let some inner part slide out. I'd like not to destroy anything.
Thanks for the link. It is interesting even if it is for a much newer
