View Full Version : Got in a KV-8000...
Sandy G 11-21-2011, 08:07 PM From '77. I know it ain't perzackly a primo set, kinda fugly, really, but its in reasonable shape, & bein' its a Trinitron, it still works perfectly. And I've not got a king's ransom in it, either. Also got in another one of those funky JC Penney 5" B/W TV/scope units...This one works, but need De-oxit, & a general cleaning. WHY do I LOVE these damthings so ?!?
jr_tech 11-21-2011, 09:05 PM Cool! those are fairly scarce, I do not have one....yet! I have always wondered if that set uses a CRT with directly heated cathodes (like the KV-5000) or indirectly heated cathodes (like the KV-9000). If the set has been unplugged for a while, how long does it take for the picture brightness to come up to near full when the set is plugged in and quickly turned on? Does the brightness come up quicker if the set has been off for a while (but plugged in) and then turned on?

Sandy G 11-21-2011, 09:51 PM Seems like it "Steams in" full bore right after its turned on...
jr_tech 11-21-2011, 11:21 PM Seems like it "Steams in" full bore right after its turned on...
Even if it is "dead cold" as in sitting unplugged for an hour or so before being turned on? :scratch2:

Sandy G 11-22-2011, 09:36 AM Yep.
jr_tech 11-22-2011, 11:09 AM Thanks!
Then the KV-8000 behaves like the KV-4000 and KV-5000 in that respect, and likely has low-power directly heated cathodes in the CRT! That makes sense because the KV-8000 is also designed to operate from a battery pack. As far as I know the KV-9000 never had a battery pack, and uses slower warm up higher power indirectly heated cathodes.
Somebody posted here that the CRT in the 8" S0ny monitor racks used indirectly heated cathodes, so possibly S0ny builds the tube both ways, depending on application. :scratch2:

rpm1200 11-22-2011, 04:01 PM I can verify the KV-9000 has an instant-on circuit with no vacation switch. It's also AC-only, typical transformerless hot chassis power supply.
Sandy G 11-22-2011, 04:13 PM Well, that's cool...I NEVER plug ANY of my stuff in unless I'm wanting to actually use it...Had a direct lightning strike summer Y2K that took out my Yammy CA-2010, CT-1010, B&O TT, JRC NRD-535D shortwave set, & a MINT Panasonic CT-3311, so I kinda learnt my lesson the HARD way...
jr_tech 11-22-2011, 04:49 PM Ouch! :tears:

Yes! The KV-9000 uses indirectly heated cathodes in the CRT, but if the set is plugged in the "instant on" circuit produces a quick turn-on of the CRT (several seconds) similar to that of the KV-4000 And KV-5000 series sets.
I just performed the "dead cold start" test on a 9000 that had been unplugged for a while and the CRT took 15 to 20 seconds to come up to a reasonable brightness. If the set is plugged in and turned off a faint glow can be seen from the heaters in the CRT.

Sandy G 11-22-2011, 05:49 PM Yeah, CT-3311s are seemingly a LOT more rare than their little bros, the CT-101. But only full bore, bull-goose Loony TV Nut like Yrs Trly wants BOTH the Smallest color CRT TV ever made, & the 2nd Smallest one, too.. (grin)
mpatoray 11-22-2011, 08:57 PM I love my KV-8000, mine has been modified by "Videotek" to have BNC and EIAJ-8 A/V I/O. I also have the KV-9000 that has had the same done to it along with a honkin big isolation transformer in the bottom.... The tube on the 9000 is much weaker
kx250rider 11-23-2011, 12:05 PM Nice find! I wish I could find the BP-8 battery case for that set. Seen one on eBay, but they wouldn't sell the battery case without the TV, which happened to be NIB.

jhalphen 11-25-2011, 03:32 AM Hi Guys,
Over here in Europe, Sony's PVM-9000 was a portable 8" PAL/SECAM color Monitor with a striking ressemblance to the KV-8000.
In its heyday, it was a favorite bring along field monitor for video field production when the director wanted something bigger than a 4" screen or the tiny JVC TM-P3 (3") to check color balance on a remote shoot.
Like the KV-8000, the PVM-9000 had a DC power input for un undertray filled with Ni-Cd batteries.

ctc17 11-30-2011, 11:35 AM Im in the club! I found one in the garage yesterday. Works too, has some vertical issues but no big deal.

jhalphen 12-01-2011, 04:48 AM Hi Sandy,
Congratulations! on bagging a JVC TM-P3.
You're learning one of the best virtues of miniature TVs: inbuilt wife detection defeating stealth! you can come home with a CT-101, TM-P3 or a Sony PVM-4000 4 inch color viewfinder and keep a poker straight face.
Tip: The parcel/box can pass as a photocopier spare selenium cylinder, as the H/W/D ratio is about the same. Better still, scrounge an old carton from the office, your supply or a friend's with an HP, Epson, Kyocera marking and store in your car's trunk. When you find the monitor of your dreams, hide in box.

or here, sold as an analogue color + waveform field monitoring combo. Often cheaper sold as a combo vs as a standalone color monitor, go figure...

see bottom of page 2 & page 4
The TM-P3 comes in two flavors:
- NTSC 525/30 USA with color & tint vontrol
- Euro PAL/SECAM 625/25.
Same size, same outside aspect.
The sony PVM-4000 has a super-fine trinitron CRT pitch and gives jaw-dropping beautiful pictures. The monitor is quite deep though (about one foot), as Sony opted for a very shallow 45° deflection angle to preserve perfect geometry.
Collect them all! they will get scarcer as LCDs massively take over Broadcast centres. Also enjoy what used to be multi thousand $$ pro electronics for a fraction of their original cost. If shopping and the monitor is sold as "working", ask questions before about dim (highly used CRTs) and the scond plague of ex-pro use: visible time code phosphor burn-in. If you're not familiar with that, think of old airport flight number display screens in public halls.
