Those 2A3s are Single Plate (vs Double Plate) and are worth quite a bit of cash, check ebay sold items for values. They were used in high end radios from the 30s - Scott, McMurdo, Capehart, RCA, etc..
The old radio station near me has a set of 4 neon bulbs that their phone line runs through. The bulbs flashing indicate an incoming phone call in the DeeJay booth. They took the bells out of their desk phone so it couldn't ring in that booth. The station turns 71 this valentine's day and going into that place is like stepping into a time machine. The DJ booth's walls have rows upon rows of 78rpm records. If you go out behind the place they have a trailer with a WWII vintage generator on one end of it and an anti-aircraft 1 million candlepower spotlight on the other end which is what the generator powers. They used to use it at stuff like the grand opening of a store and it looked just like those spotlight beams on a 20th century fox logo as you can see it shining up into the air from miles away.
Those neon tubes probably will unscrew from the bakelite bases. Glad this stuff was saved from the landfill. Some people would think all this stuff is just a pile of junk and toss it. Some of those old bulbs might have a carbon filament. It is a shame they are damaged. I believe they are similar to those bulbs that will last 100 years.
I used to use those 200w bulbs in our barn to light it up good in there as it had 4 ceramic bulb holders so had a total of 800w in there, lol. Years later we put 2 four 4ft florescent banks of lights in the front half of the barn but in the back half as far as I know it still has just the ceramic edison base sockets. My Sis sold the place in 2010. Now out in my garage I have a set of three 4ft florescent fixtures over my workbenches and 3 ceramic edison sockets on the other side of the garage with 60w incandescent bulbs in them. When I go to test a radio I turn off the florescents and turn on the incandescent bulbs for less noise interference.
Winner, winner chicken dinner. You have the most NOS and used tubes I have ever seen on any UA-cam videos! It is a great treasure to have .You will always find one you're looking for once you get them better organized.😏 What a great collection of light bulbs. Some are very unusual neon types which I didn't know existed.
Thanks for giving us a front seat view of your rummage Bob ! Some very interesting devices there. I know there were multiple uses for the neon lamps; night lights etc.. but I also know that experimenters in the mechanical TV era of the early thirties used the large neon bulbs as light sources because the thermal lag in incandescent lamps rendered them unsuitable for this purpose. There were in fact bespoke rectangular plate neons produced at the time for TV usage but many experimenters went for the general purpose, cheaper option.
The ham tubes take me way back. I'm not as old as some of them, but getting into the hobby as a kid, these were the types of gems I would bring home from hamfests back in the day.
I like your mat but if I were you I'd go to walmart to the sewing section and get a self healing cutting mat and put it where you put your chassis you're working on as it will last a lot longer than that mat you bought. I cut to size and use those mats like yours in kitchen drawers, under speakers and even under area rugs on wood floors to keep the rugs from moving. I also put them in the drawers of my tool boxes.
Thanks for the tips. There won't be any chassis on this workbench. It's just a tube testing station. The new main workbench will be much larger and I'll use a different surface. I like your idea of using a mat that can be replaced as needed.
2A3s are still used in some pretty hard core new audiophile amplifiers. With one tube running single ended you can get about 3-4 watts. The 6L6, 12AU7, 6SN7 and 6SL7 are also used in some high end audio amps. If you dig up any Western 300Bs, start planning your next vacation. A bunch of those bulbs in the last box look like automotive bulbs. Certainly the 1156 is an auto bulb that's still made today.
I see on ebay they price some of those box plate 2a3s at over $500 each ! And the 12ax7 prices are shocking as well. I think you have a gold mine there, but dealing with selling tubes on ebay is not as fulfilling or fun as restoring radios and TV's. I'm sure glad to see his estate went to a collector (you) who appreciates the engineer's stash as much as he did . Congratulations !
THE mild UV lamp is actually very rare, mad in the late 30s. It only have a lifespan aof 25hrs. It certainly does not produce enough UV for exposing anything, due to its technology. The lamps from 44 are partly very old. the second lamp out the box is indead not as old as the others from that box that might 100 or a bit older. You can see on it that the evacuatiopoint is a tube in the part near the base colled the stemm, and the nipple on the top is mor of a gimic. The blue one ones is the most interesting. It is not UV nether mercury. q carbon filmanet is not hot enough to produce UV, however it procuces a lots of infrared radiation. From 53 min on in the bottom box there are reflector lamps with Ba15d cap for planes, liekly 28V (I want xD), most of the lamps in their seem to be for palines. . Not That neon NE 55 needs an external resistor for current limiting Ne29 is a new one to me. 60V 10W is for telefon exchanges. 58:51 is for a plane headlight. 59:01 was used an a aparautus for cutting sound tapes for old films.
6146s are a VERY common final amp tube for HF ham transcievers. A pair of them will give ~100W on all the HF bands. Were used up into the 1980s in Yaesu/Kenwood/Icom rigs. The 829 and 832 are dual tetrodes, not dual triodes. The 829 is approximately a pair of 6V6s in one bulb. Unfortunately, they have a common screen grid pin, so no ultralinear operation as an audio amp.
Very good collection of mostly useful tubes for sure! Good that the metal tubes are in good shape. Must have been stored indoors and not in some shed or garage for 50+ years.
the 115w bulbs may be traffic control bulbs-I actually use 116w bulbs for when the guy goes up on our tower and has to change the side marker bulbs and they are traffic control bulbs with a very specific wattage
Several of my pieces of Ham gear use the 6146 & 8198 tubes and they were common in some commercial gear. 1156 is used in cars as a tail light or license p[late light. Some radios used a bulb as a fil dropper, and I have seen neon bulbs used as an oscillator and also antenna protection.
“A piece of test equipment where a [special] lamp is a key component” I’m guessing you’ve got an HP 200 audio frequency generator? IIRC, Bill Hewlett did his Master’s thesis on that bulb-incorporated oscillator design, then later when he teamed up with David Packard they marketed it as their first commercial product: the model 200
@@bandersentv I got one in an estate sale a few years back (the ‘D’ version), and yes they are HEAVY 💀 Mine’s completely original/unrestored and still works flawlessly! (save for the dry-rotted vernier clutch) It’s capable of LOT of output, and consistent amplitude across the entire range!
Looks like Bob will need to get *lots and lots* of tube boxes as he adds this massive score to his stash! Quite a bit of the stuff he has shown appears to be World War II-era/war surplus. His tube testers are in for a workout! That's a pretty smart idea to have that mat on that workbench to protect any misbehaving tubes.

Those neon bulbs would make good stroboscope projects, and most Neons will work on DC only one electron will light up on AC both electrodes light up and at audio frequencies you can see the AC
"D-lab Electronics" designed a 6W class-A guitar amp around a 2E26 tube. 6W6s are a bit interesting in that their descendants are found in nearly every AA5 radio as an output tube.
I could use that 6J5 and 6F6. Also just a question my vintage tube amp the output transformer gets really hot can still do the 5 second finger test but palm of my hand if leave it for 4 seconds it hurts and hand is red. Should I be concerned? Also the caps on top of chassis are warm
@@bandersentv they might be warm from tubes near them. But them being warm might be why transformer is getting hot. If I notice more hum then what I'm hearing now will replace them
When I was a kid and afraid of the dark, my dad brought me a neon light that plugged to the wall as a night light. This was in the late 70s. Maybe those are an earlier version of that. Or something people back in the day used to make a romantic mood in a room...
Wow what a collection of great tubes and bulbs! I think we are witnessing your retirement nest egg!
Hello michelly Brazil thank you kiss Brazil 😙😚👏👏👏👏👏
57:30 Many of those look like they could be projector bulbs. The one with the ring looks like one that goes with one of my editing projectors.

Yes, they sure are. I'd heard about the single plate style but never held one in my hand before.
Those large neons were indicators for power busses in factories.
large neons were also used as hospital nightlights and hallway nightlights
@@DanafoxyVixen I found an advertisement for that actually. For using them as a night light.
I saw a nightlight ad too.

Those bulbs at 57:46 with the odd base with holes are for slide or film projectors
And microscope illuminators.
They are "exciter lamps" for optical sound-on-film in 16mm projectors. Used with a photodetector to reproduce the sound track.

It's probably a good idea to power antique light bulbs with a variac to reduce the thermal shock encountered when going instantly from zero to 120v.

6G6-G is a triode twin diode like a 6B6-G. Predecessor to the 6Q7. Some of the radios Dave Tipton worked on had them.
Thanks. Strange that I've never encountered either of those tubes.
Sorry, but a 6G6G is a low power output pentode with a 150 mA heater. They were designed for vibrator "farm" radios.
@@stuartirwin3779 Sorry, I stand corrected. I was confusing it with a 6G8-G which is a remote cutoff pentode with two diodes.
@@danielthomas3057 Indeed, although the 6G8G was interestingly unique to Australia.
Could those neon bulbs also have an application in photography,? Might serve as a safe light source in a darkroom
I couldn't find any reference to them being used in darkrooms. Just for night lights and scientific applications.
do you have a SW radio on in the background. periodically in your videos there is a long tone that plays. 23:49
No, that's the furnace. It's only a few feet away
