GM Jeff,
Maybe an easier exercise would be to convert one of the 60s to 160m only? This
might be especially useful if you are going with crystals only.
Initial thoughts are:
Add parallel capacitance to both C22 and C24.
Rewind L3. and L2 for 160.
L1 may or may not need to be altered. The oscillator circuit is a Pierce
circuit which usually behaves pretty well. L2 is likely the main tuning element
for the second amp/doubler circuit so only L2 may need to be rewound.
You can bypass the bandswitch; that simplifies matters a lot. :

I have a couple of Heath DX-60 transmitters. I'd like to convert one of
them to 160. This would involve re-doing the 80m section of the rig.
Does anyone have a step-by-step article to do this? I did an internet
search but found nil. Maybe one of the magazines (QST, 73, CQ, HR) might
have run an article on this way back when.
