Old Timer Needs CRT Help

8/31/2010 2:23:28 PMBrendan

I've been working on radio's and electronics for a long time. My grandson has gotten into fixing and restoring old Acrage games (70's,80's, 90's.). Many of these have weak CRT's. I suggested using my RCA WT-333B tester/rejuvrnator. to bring them back to life. I have a lot of the adaptors for this, but many of them don't fit the newer tubes (or are wired incorrectly). Does anyone know where I can find CRT base diagrams on the web? Or if there is a book we can buy? Then we could just use clip leads. Thanks! Brendan

Brendan,

You might try the antique TV forum at antiqueradios.com and videokarma.org.

Just so you don't think I'm a nut, the first thing I did was to Google that same as you did. I spent a couple of days following up all the links. The problem is that this seems to be all for older tubes (40's into the 70's) with almost nothing listed for the newer monitor CRT's. I already have the older information and need some of the newer stuff. Thanks for the come back. Brendan

Brendan,

Don't know if this will help, but this site above is involved with computer monitor repair.

Sir Brendan. . . . .

I gave up on those increasing numbers of "special adapters" many decades ago, with my infrequent need of testing or banging kines.

Instead, I just incorporated an octal socket, connected into a cable and terminated that cable end into a small bakelite box with its plastic panel on top. (With that chosen sizing being in the order of ~1/4 of a Triplett or Simpson VOM case sizing.)

Then I had the 2 leads for filaments an then both of the three possibilities of either RGB cathodes AND RGB grid connections at terminals where my individual string outs of color coded ~#24 stranded wire extension wires could reach over to the tested kine.

As far as their end terminated clip leads, the only ones that I would trust as being small enough, would be the Pomona or its knock off variants of E-Z clips

And then I realizd that the most of the kine socket pins were the same sizing as common computer DB-25 connectors so I started breaking up connectors to get the female connectors and then butt soldered them to the ends of the wiring ends an THEN double covered with heat shrink tubing and then had an absolutely marvelous connection pin to slip over the kine pins.

Only having to return to the EZ clips when encountering some of the small-slim spring contacts like some Zenith kine connectors were using instead of pins.

Lastly what we . . . . really, really, REALLY want ( . . . . . . a la Spice Girls ) is the probably few kine numbers of the kines that you will ACTUALLY be involved with.

With my probably already having some of the data on the last tubes that were still retaining the first numbers being relevant to the kine envelope size . . . .on the older generation of kines.

However, some of your latest numbers may be encroaching in the later utilization of the scame numbering but using metric sizing instead . . .to wit . . .A68ACT00X . . . . 68 CM or a 27" tube, but not that you would be using that large of a size in a gaming monitor.

Probably with their numbers being in the 420 or 510 series.

Thassit . . .
