You will have to pry my Viking I out of my cold dead hands. The external
122A VFO is solid as a rock and even the 4D32 final is now cheaper than a
6146 and 807's are often freebies NIB.
Simple to improve the audio, loads into anything, and easy to use the full
audio section as a driver.
I had a DX100 in around 1957-8 and was happy to get rid of it and buy a
Viking I. Now Ive got another one.

Hi Guys,
I agree 101% with all of the positive sentiments re. the Viking II --- it
looks good, sounds great (with a minimum of fuss in the "mods" dept.), and
is really quite easy to work on, IF you don't mind the weight...!
Mine is the rather unique & rare Canadian version, built for the Royal
Canadian Air Force 'way back when: it covers the entire SW spectruum, so
there is no "band switch", as such --- just multiple frequency ranges, on
all of the different switches.
It is NOT the U.S. Civil Defence version, but a different animal in and of
itself...
...Best of all, I picked it up a coupla years ago for the king's ranson of
$60.00!

The VFO may not be built-in, but Viking II's, when working proper, are
kinda hard to beat.
As with any rig, simply replace a few caps, make a couple of mods (PTT,
audio) and you've got a solid 100w performer.
One could even change out the 6AU6's for a pair of 12AX7's, using the
first one as a Crystal Microphone equalizer, and inverse feed-back, the
2nd for amplification, into a phase-inverter that would then connect up,
capacitively to the grids of the 807's to get around the weak link in
the audio chain, the audio-driver transformer.
Yeah, I know the thread is about 'Heathkit' rigs, but one 100w
plate-modulated AM rig, is as good as the next 100w plate-modulated AM
rig.
Apache, DX-100, Viking I/II, any of the 32V series, B&W 5100, etc...
