[Boatanchors] Hallicrafters SX-42 - Restore or Parts?

[Geoff]

If its complete with no major damage its best kept together and sold to 
someone with enough experience on that model to do it justice.

There are plenty of parts sets available since the SX-62 family shares all 
the problem parts.

And good luck finding a schematic that matches any 42 or 62. Ive done about 
a dozen of both and every one has its own little differences but it shouldnt 
slow down those experienced with consumer products and poor documentation.
