Tubes, anyone?

[dood]

Just a few NOS tubes in this lot...











Some are audio... some are TV.

I'm still sorting through to see what I've got. Some are junk, I'm sure... some even have "weak" or "poor" written on them. I don't have a tester, myself, so I'll have to pull out the ones I think will sell and take them to a buddy who has a tester.

I'll let you know if I come across anything interesting. Or are you looking more for mundane?

Re: Tubes, anyone?

I've taken interest since seeing some valves/tubes on eBay in 2002 when I was looking for something else, and I bought my very first valve radio a year later at a swapmeet.
In the radio I bought (there was even a circuit diagram taped inside it; a rare sighting), I successfully replaced all of the paper capacitors and that gave me confidence in restoring valve/tube equipment, and this radio runs beautifully today.
There are some songs which remind me of glowing valve/tube heaters at night too...

Re: Tubes, anyone?

I used to have a TV with so weak emission that it needed the heater cranked to the point the CRT was glowing bright yellow. Doubled as what Philips calls "Ambilight" today.

I'm not into tube audio though. I went and auditioned some homebuilt tube amps once and indeed they sounded beautiful, but that was on $1300 speakers and a treated room so it was an unfair comparison.

IMO the most important aspect in quality audio is the room. Second is the speakers, and only then you can start thinking about amplifiers. I have a pair of vintage bookshelf speakers that are worthy of being studio monitors when complemented with the subwoofer i built into my desk. Unfortunately, the room and their current placement makes a really big hole in the midbass. Regardless what speakers i would put in here, they would sound the same. Oh yeah and the subwoofer sounds best when i'm out in the hallway...

Japlytic - As I'm sure you know... be very careful working with tube amps! 300vdc is nothing to ignore...

Th3_uN1Qu3- That last paragraph would launch you into a debate you wish you hadn't gotten into if this were an audio forum :P

Re: Tubes, anyone?

QFT!
btw my favorite sport is making audiophools eat crow.my favorite was a blind test of about 10 different 12ax7's in a preamp.
set this up at the milford hamfest.at the end 4 different guys gave totally random results other than reliably noting that the jan military industrial coiled heater and triple mica ge's had the lowest hum and background noise.
those were from a $5 bucket lot i got at the hamfest.50 years of dirt/dust included.didnt even test them.just grabbed two and added them to the test lot. deflated a few ego's of the guys buying $400 matched quads of mullard and telefunkens!

Re: Tubes, anyone?

When I closed my TV shop, I gave away TONS of tubes and a big console style tube tester. Probably worth a small fortune now.....but ohh well... Nice score.

Re: Tubes, anyone?

Reading Kc8adu's comments makes me think back to an English song performed by Flanders & Swann back in the late 50's called Song of reproduction.
Check it out on Youtube. Guaranteed to raise a smile.

The prices now for ECC83's or 12AX7 as you guys across the pond would call them are ridiculous. I think most of this nonsense is brought about by the guitar amp fraternity and audiophiles with better thinking than hearing and deep pockets of course.

Ask any audio engineer who's been into mixing or mastering and he'll answer the same. Most mastering engineers would rather pick a great room with so-so monitors than a bad room with great monitors.

Re: Tubes, anyone?

I've got a fairly sized collection of small tube-type tabletop radios, as well as a couple of TV sets. Of course, with all this, I also have a fair amount of extra tubes hangin around.

If you get to sorting through your collection of tubes there, post some tube types? I may be able to use a few extras that I don't already have.

Whew! No wonder I can't move around here sometimes...

Re: Tubes, anyone?

Lots of TV tubes in that list.

All the ones with oddball numbers (not beginning with 6/12) were used in "hot chassis" TV sets with series wired filaments. Anything to add the total filament voltage upto 120

6LE8 can be used to make a very functional AM transmitter (Look around the Antique Radio Forums for info)

33GY7 is a common tube in zillions of portable B&W sets of the late 60s and early 70s.

6GH8 was common in early color TVs, and was a major headache to many repairmen of the time, as some would work in one position of the set, but not another, and vice versa.

[kc8adu]

Re: Tubes, anyone?

i use 6js6 in my ft-101e.
and i remember buying 6gh8 by the hundreds.lots of bad ones in those old color sets.

[smason]

Re: Tubes, anyone?

I thought the 101 used 6L6es? Man your pics bring back memories, but I don't miss tubes.
I could use a couple 807s but the cold variety

[Hemingray]

Re: Tubes, anyone?

And not a single AA5 tube of any sort in that list! Surely there's at least 30 of those hangin round those boxes (50C5/50L6, 12BE6/12SA7, 35W4/35Z5, 12BA6/12SK7, 12AV6/12AT6/12SQ7)

"6GH8 was common in early color TVs, and was a major headache to many repairmen of the time, as some would work in one position of the set, but not another, and vice versa."

asides from the differences in inter-element capacitance , gain , miller capacitance (etc) between runs and manufacturers , one problem was the cathode sleeve to surface oxide boundary layer .
for some reason this would tend to mess up the operational parameters of the circuit .
RCA did extensive research into this area and had tight quality control .
this came from a guy that ran a shop and his brother was an engineer for RCA .

i seen a lot of sets that came into the shop that had been "drug store tube seller/tester-ized" .

[Hemingray]

Re: Tubes, anyone?

If you come across any of the AA5 based tubes, shoot me a price. I can always use a few extras.

[kc8adu]

Re: Tubes, anyone?

nope.6js6.i modded one to use 6146's a while back when i didnt have any good 6js6's on hand and will never pay more then $10 ea new for them.asking price everywhere was $50 ea at the time.milsurp 6146's are plentiful and cheap.an actual transmitting tube is a nice bonus.

[mstamper]

Re: Tubes, anyone?

I could use some 6an8s and 6cw4s. Are you interested in selling these? If so, how much? Thanks.
