Anyone need a tube tester?

I scrounged up a B&K "Dyna-Quik Mod. 500 tube tester today. Has the

510 daughter board inside the lid. Case is not bad, inside looks pretty good. sockets look excellent, and none are broken. Ball chain that holds the lid upright is broken. There is one tube base adapter

Best offer plus fair shipping from 91763

I can shoot a pic if anyone wants. No documentation, but there is a clear and clean chart inside the lid. "Pax Americana is a philosophy. Hardly an empire. Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules.

Think of it as having your older brother knock the shit out of you for torturing the cat." Gunner

See it your buyer wants to buy my copy machine. I still have a box of negative paper for it and 2 quarts of developing fluid...I forget what they call the process but it 'kinda worked. I also have a CP/M computer with SSSD 8" floppy drives and a 9" mono composite monitor, hand built-worth more! I also have a TUBE TESTER!

Gunner, here's the phone number for BFI in your area:XXX-XXX-XXXX If you call them, I will too.

Check the prices on Ebay before laughing too loudly....lol Even for your computer. Kaypro? Heathkit?

The folks on rec.radio.amateur.boatanchors would be interested. A picture would help give people an idea of the era of tubes that it would test -- I have a nice little tube tester already, but it doesn't test anything older than about 1938 (it has miniature, octal and loctal sockets, but no 4- 5- 6- or 7-pin big sockets).

There are some audio guys and musicians (guitar amps) that *WANT* that "tube sound" and pay large to get it.

I thought that was fetish bullshit for quite a while. After finally studying the matter rather than smugly hooting, I now see why "tube sound" really might be more pleasing to some or most. It's not the same as the gold plated power plug stuff which is utter bullshit. Tube amps don't intrinsically distort any less than silicon amps, but they do distort differently -- and the difference in relative strengths of various harmonics (distortion) is more "musical" to some ears. One key to this is "balancing" some of the tubes, particularly the output tubes which often run in matched pairs. A good transconductance tube tester would be very useful for selecting a best-matched pair out of a bunch of found tubes. The cheaper emission testers were really only good for weeding out dead or near-dead tubes at the drug store. I don't know which flavor Gunner's is, but being B&K I'd suspect that it's a good one. If there's something on the meter that says gm, bingo. Gm is transconductance.

Don Foreman -- who is struggling mightly (while whining miserably and bleating pitifully) to learn to use microcontrollers and program in C, but designed tube circuits many moons ago and still has the RCA tube manuals.

A Xerox 820 also called a "Big Board", bought the bare board surplus and soldered all the itty-bitties. I was hooked on text adventures like "Zork" ...(XYZZY-the secret password) I used the tube tester in college to repair TVs cheap for students and make beer and film money.

And while you're out testing your tube, someone is waiting for you:

Repairman at a sound company and i do live sound. Still ahve that bench set up amongst my others and i am setup to do almost everything but PCB's (tubes through test circuits when needed).

Don you are dead right the "Guitar" sound has nothing at all to do with fidelity of reproduction of the original sound. Guitars and guitar amps (Even "Clean" ones) are more about getting a distorted instrument sound thats pleasing to the ear (Even harmonics instead of the odd harmonics produced through switching)

Fidelity only kicks in at the microphone facing the amp and at that point its treated as a separate signal source and whatever distortions the guitarist wants are now treated by the sound guy as the "signal"

As a result those distorting footwarmers of tube amps do that job perfectly where integrated circuits are much better suited for reproducing sounds with fidelity to the signal rather than adding their own "Warmth"

Anyone who still believes in the bullshit about Iraq's chemical weapons may want to buy a chemical weapons alarm from me. $15 plus shipping. It needs an extra sensor plate though, sold on the internet. I have 3 remaining, sold about 18.

Oooooh!! Great shades of Vargas!

Yummm!

Which brings to mind several things that occurred when I was installing alarm systems..which I will NOT repeat here.

I already have several, including the detection kits. Not all of us plan on going to Iraq..but a number of folks live in areas that may have industrial accidents indistinguishable from gas attacks.

Indeed.

Hidden mini-cams in "smoke alarm" boxes come to mind. That must have been a tough one to avoid installing in some of the sweeties' bedrooms, huh? It's good that you have the character to ignore it.

Adventure - the first real good one for pc's - Plugh ! Yep - still use those for keywords to remember - like my book program - sort by a simple code.

I had Adventure - on Hard Sector 8" floppy on my 8080 Altair 8800 B - had the first 8800 in January but upgraded to a B for more power.

Is there much market for tubes? I'll got about a hundred.

How about speaker shims?

I use to help a guy balance engines. He had an old Stewart Warner balancing machine that had tubes in it. One day while shutting down I noticed the machine was on so I shut it off. Next day we came in an he noticed it was off, and I told him I shut it off. Boy, he said , you just killed it. Sure enough, thing wouldn't work. As long as the machine stayed on everything worked, shut it off and the tubes would go bye-bye. Sent it back to Stewart Warner and they dusted off an old retire E and we'd get it back in two or three weeks. Thing would crap out in power failures to, sometimes. Dam good machine. Pick up the slightest imbalance.
