Why? There are PILES of tube type SW receivers available
now FAR cheaper than you could build one.

Hey, I get it. It'd be a fun project. I've thought about doing
something like this myself but seriously consider the cost.
Not just of the parts but the time involved in the design,
marketing, and *liability insurance*. Bet you didn't think
about that one!

Liability insurance is tattooing "SUE ME" on your butt cheeks.

The general aviation industry nearly put ITSELF out of business by
answering every lawsuit with....you guessed it...more liability
insurance. The scuba diving industry instituted a certification
program and convinced all the attorneys that if a noncertified diver
killed himself by the traditional methods (embolisms or drowning)
juries would just laugh at them. Sport diving equipment companies do
not carry PL coverage except for tank explosions out of the water. No
one sues them for diving accidents. If they did they'd get the keys to
an empty warehouse. The sport diving companies are all turnips,
judgementproof. The COMMERCIAL diving companies are very funny as to
whom they will sell. The few eccentric hobby hard hat guys will attest
to this.

You can buy scuba equipment for a lot less today than thirty years
ago, in adjusted dollars. Airplanes have gone up by a factor of three
or four or five.

Buy legal insurance, and incorporate yourself so that you can not be
construed to have a personal holding corporation. But never buy PL
insurance or if you do have it strictly limited to a circumstance
which is incidental.

As to the piles of existing sets, yeah, there are-most are in bad
need of restoration. And most of them weren't worth a **** new. The
few good ones are carefully husbanded. The surplus Collinses and
Hammarlunds are about gone.
