Max, what took you so long to find that place? You are trying to think of either Webb or W&W Electronics on Clinton Street. It's too late to buy the 1920s radio on display but you can still look at it.
@radionut - I think the reply only workd for a few levels else the columns get very thin (this used to happen...!)
I also learned a lot from the "In your workshop" columns, they were very instructive. I had quite a few copies of the Radio Constructor - it was another good mag from the old days....
I can't see a "Reply" tab on your recent posting but you're spot on with Dick and Smithy being in the Radio Constructor: their exploits were related in the "In Your Workshop" column and I learned a lot from them.
Ax-man surplus (http://ax-man.com/) in the Twin Cities is always a lot of fun. I put together a TV remote control (read: wired solenoid-based channel button pusher) for my dad from Ax-man parts back in high school. It even sort of worked.... ;)
They have scads of stuff, not just electronics. I just about bought a pair of airline seats as college dorm furniture, but unfortunately didn't have any friends with a pickup truck to haul them to Chicago. Ah well.
By the way, your transmitting tube looks a lot like a 304TL/TH, or something similar but a bit bigger. Those are transmitting tubes capable of plate dissipation of a few hundred watts. Friends of mine used to make decorative mantelpiece displays out of tubes of this class, actually lighting the filaments. Some are fairly bright, but all have a nice warm glow. The power requirements are generally too high to leave them on as night-lights, though ;-) . The 304TL filament is, IIRC, somewherein the 30W range.
In the 1960's, I used to go with ham friends from my home in northern Oklahoma to surplus stores in Wichita, Oklahoma City, Kansas City, and once, the epitome, the Collins Radio surplus store in Cedar Rapids, IA. It was sad to see them disappear, one by one. I still fondly remember picking through a huge pile of scrap electronics at a place in Oklahoma City and coming up with a couple of dozen ceramic-metal transmitting tubes. The guy hefted one in his hand to guess how much copper was in it, and sold me the whole lot for scrap copper price (a buck or two - total).
There's a place that sounds much like your Mock Electronics in Orlando, FL , called Skycraft Parts and Surplus (they have a website, google for it). I have been rejoicing finding this place since I moved here -- you can't "just go pick up something", it's just too hard to get out!
That's all right, Max, I'm just happy that we can have conversations like this. I didn't get to see too many editions of Practical Electronics as a young lad,or Practical Wireless for that matter, as my favourite was the Radio Constructor and that's what soaked up my pocket money...
I note that my earlier comment has a 9:38 time tag but it was sent before your 9:33 statement appeared on my screen. Hence the sequence of this thread may appear a bit strange.
Cheers for now.
