Well, the Molex female terminals are about as small as anything can get and still allow you to solder onto it. A few of the board's WW pins would be easy, since the old leads have enough slack to simply attach a Molex terminal on the end. A number of leads are tight and would need lengthening. There are at least three WW pins with two wires attached.
Meanwhile, the new K7 couplate works fine, but the height is still deficient.
The 400V boost voltage measures 400V on the money. On the 6DR7 vertical tube, the voltage at the oscillator grid is low (-.03V rather than -3.5V) and the plate is somewhat high (155V rather than 115V).
As with the horizontal section, caps & resistors around that tube have already been replaced, which leaves couplates K4 and K5, I guess.
