Sony KV 5000/5100 Differences?

I think all of the Sony sets I have owned, and installed/worked on in airports, have been at full brightness within 10 seconds or so, back to my 1979 KV-1922. Once the CRTs get weak, though, it takes much longer for what brightness you do get...

I couldn't agree more. :-)

I stand corrected... The KV-5000 and 5100 both have non-instant filament supplies which come from the FBT, and being that the both use the same CRT (SD-59), I don't know why only the 5100 has the "econoquick" badge. I got confused with the KV-9000, which does have instant on and a separate filament supply transformer (I double-checked before stating this time, LOL).

Thanks for pointing that out, and sorry for making an assumption based on a bad memory of models ...

I have seen 5000s both ways, I presently have a 5000 with the "econoquick" logo below the UHF ch selector knob. My earlier 5000 (which was stolen) did not have the logo. The manual that I still have from my first 5000 does not show the logo.
S0ny sometimes takes a while to "invent" these terms... The first "Walkman" was just called a "TPS-L2"

If you you still have your KV 5000 manual, is there a print date shown any where? I'm trying to establish a valid introduction date for both the 5000 and 5100.

Sorry, None given, that is one of the first things that I checked for after I dug it out. There is a part number 4-495-409-21 (1) perhaps a S0ny expert can figure it out from that?

Sams Photofact for the 5000 is 1457-3 (early 1975) and for the 5100 is 1652-2 (mid 1977), if that helps.

There are versions of the TPS-L2 with and without the name "Walkman" on them. I remember selling every one of those we could get our hands on, in a little store in Evanston, Illinois in 1980-81.

i have a kv-9000 that i fired up after it sat 7 years.first firing took about 45 seconds to fully brighten up.about 20 from cold and instant if it has been plugged in.i guess this one dodged the slow death of instant on!it still look great on the lone analog station we have here.
i have several kv-5xxx sets here too.the 5200 is ready in about 6 seconds.however these directly heated tubes have an odd failure mode that i have seen several times.k-k leakage.i replaced the crt in the 5200 for that reason.

It probably had a new face bezel put on due to scratches. Many of them did, and in fact, the shop I worked for in the 80s, kept 2 or 3 in stock. There was no option to order the early one without the Econoquick badge, so they all had it when replaced.

I have both of the original Sony manuals, and the original 1st ed's are dated:

KV-5000 = 1973

Supplements and corrections as late as 1994.

KV-5100 = 1976

Supplements and corrections as late as 2005.

By memory, the last KV-5100 I saw new in a store, was at a Sony authorized retailer in West Los Angeles in 1981. It could have been on the shelf for a couple years, much like a drug store in Northridge, CA which had a few Panasonic CT-101s in stock til 1994 (was a 1982 set). Small and expensive TVs seemed to sit awhile.

kx250rider... good thought about the replacement bezel... they do seem to scratch easily!

Speaking of 5" 'trons, has anybody seen one of these before?

IIRC, the 5" Trinitrons had the same kind of "Cachet" that their older B/W brothers had back in the early '60s...Both were kinda "jewel-like", performed VERY well, & were fairly expensive when new.

Good stuff. I saw your previous thread where you dated the 5 inch Sony's. Wanted to be sure on the dates.

No! Interesting. Looks to be a Japanese market model with 100 volt power supply. I believe Japan is NTSC, but previous experience with Japanese market sets: won't accept a digital converter box signal. I could be wrong on this. It still has video/audio inputs, but not sure about that power supply working properly.

The tinted screen cover can be removed easily. You can use a jeweler polish paste to remove most scratches. Several applications will remove all but deep scratches. I use a product called "HAPPICH" product of Germany.
