I found a picture that I took of the underside of a HW-16's power supply
section during a recent re-cap. This was taken prior to installing the
new resistors and soldering the various connections, in case anybody
wanted to see what I was talking about when I mentioned substituting
terminal strips for the old capacitor terminals.

(Note: on this job, I sawed off the bottoms of the old twist-lock
multi-section cap and drilled holes through the wafer to feed the new
cap leads through, then glued 'em down. The two doubler caps were just
glued to the old dielectric mounting wafers. Looking at the (2)
three-post terminal strips on the left, the resistors will lay
side-by-side between the strips, 33K, 2.2K, and 330 @ 5W from left to
right. The 2.2K will have it's leads in a zig-zag from the lower left
to upper right terminals. The other two go straight up and down.
Also, there will be two 100K attached to the lower right terminal, one
of which loops back to ground (bad choice of words), the other zig-zags
to the ungrounded lug just above the brown 100 ohm 10W resistor. Also,
note the ungrounded lug at the far right of the 100 ohm resistor which
is angled to make it easier to remove the lead from the RFC and the
(unseen) cap when neutralizing.
The upshot of all this is that there is more room to work in, and you
don't have such a rat's nestthere was when the *other* guy built the rig
to begin with. ;^)
Food for thought.
