Loctal Tubes

[init4fun]

According to the least reliable source of info on the net (Wikki) the name for the tube was "loctal" for "lock in octal" for all who used it except Sylvania , who trademarked the "Loktal" spelling . So if this is true , for Philco it's loctal and for Sylvania it's loktal .

And Wikki seems to be incorrect again.

Yep , the absolute least reliable source of info on the net .

"Vetting ???? We don't need no stinkin vetting !!!"

Ever wonder how wikki still exists in a world where facts shouldn't be all that hard to come by ?

Something else to make it more confusing. Sylvania was a major supplier of tubes for Philco.

I found a few tubes in my unsorted box that did not have the usual locator bump on the side of the metal base. These were mostly labeled Zenith and GM, with one Admiral tube in the mix.... any idea who made them?

If there is a 3-4 digit EIA code on them anywhere then it should be easy to tell...I've done that on some Silvertone badged CRTs I've had that I was curious about.

I didn't see any when I pulled them out of the box... perhaps the tubes are too old to have EIA code markings, or they have mostly rubbed off. I went back and double checked and did find a faint code on the Admiral tube.... It appears ro read "713", which is Taylor, a Chicago mfg, mostly known (by me, at least) for their transmitter tubes and mercury vapor rectifiers. Perhaps they did source receiving tubes for Admiral.
