Instead of converting the DX60, perhaps build a MOPA transmitter just for 160.
A 6AG7/6CL6 to a 807/1625/6146 for 30 to 50 watts output would be simple and
steal voltages from the DX60 power supply. You can borrow the tubes from the
DX60. 160 crystals may be hard to come by and feeding it with a Heathkit VF1 or
Johnson 122 VFO would make it a sweet rig. I doesn't have to be pretty and too
neat as circuitry for 160 is a bit more forgiving than the higher frequencies
if you have a bit of stray capacitance or inductance. You should see my
butt-ugly 6L6 transmitter I built on a rusty steel chassis (used to be a power
supply) I found in a dumpster. I didn't have to drill any holes ... found a
photo, it is on the left ... I have used it on 160-40. Have fun with it!

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.
