"Bugle-Boys" ? what are they, a type of vacuum tube? Do they say bugle-boy
on them? Hmmm, I had no idea the tubes seperately might be saleable. Do you know offhand, Pat, how to valuate vacuum tubes? This is interesting. Anybody know how old this scope really is? "patgkz" wrote in message ... I had an old scope like that. I pulled out all the tubes and found several Bugle-Boys which I bundled together and sold them on eBay for $60 to the audiophools. I then threw the scope out to the dumpster. "tom" wrote in message news:r5KTd.504050$8l.288888@pd7tw1no... I've got an old tektronix type 515A oscilloscope that doesn't sweep all the way across the screen, or display properly. The attached photo is of 120Volt, 60Hz, adjusted to show it most like it should be, clearly it's a diseased device How difficult a task would it be to fix? Is it worth anything as antique value? |

On 25-Feb-2005, "tom" wondered: "Bugle-Boys" ? what are they, a type of vacuum tube? Do they say bugle-boy on them? It was a logo used on some Amperex tubes. Sort of a cartoon drawing of a vacuum tube playing a bugle. They are standard tubes, but allegedly built to tighter standards. Probably like resistors used to be- somebody made a whole batch of some value, then measured each one. The ones that were within 20% tolerance had a 10 cent price, the ones within 10% had a 25 cent price and the ones that happened by sheer chance to be within 5% sold for much more. Rumor has it that God himself (herself?) uses only genuine Bugle Boys in his (her) hi-fi. |
