Wow, I lit a loaded fart off here, didn't I?
First, I said use a Hallicrafters band switch and an Eddystone dial because there's probably a market for those with old Hallicrafterses with bad bandswitches and with regen builders respectively. The problem with the Hallicrafters band switch replacement market is that there are so many DIFFERENT ones, if they were all the same they'd be reproduced. Remember rotary switches are modular, to a degree, the company that makes them builds them out of mostly off the shelf parts, and in fact you CAN get new ones built, but the problem is that they cost more than the value of most hallicrafters radios, since they have to put them together as one offs. 500 units takes the price from $400 to $25-50 each. At twenty five bucks a shot you could sell a couple hundred in six months....IF you had a unit that went into enough popular radios. Eddystone dials are a similar thing. The market has to be a mix of nostalgia and survival mentality. Yes, a solid state radio can be made EMP proof, or highly resistant, but it takes some doing. As far as power in such a situation....In the old days they used car batteries for heater voltages and a stack of dry cells, a dynamotor or a vibra-pack for B+.. Look carefully at the old Collins and National sets. They developed it to something of a fine art. As an aside, any "survivalist" with half a brain has buried a couple of solid state complete radios as well as a pile of surplus semiconductors useful post-Blast in old ammo cans. A stash of common bipolar and FETs, silicon diodes, common chips for radios and whatnot, buried under ground could be more valuable than gold and at a hell of a lot lower current acquisition price today. Some discussion on which types would be interesting. I don't consider myself a survivalist but I have a couple of guns and some ammo buried along with a couple of full jerry cans of 100LL avgas (it doesn't go bad) and some electronic stuff, plus some garage sale Craftsman tools, some spools of wire from a motor shop (short ends), and a couple things I won't mention. Better safe than sorry I figure. |
