They were made by Sampo and were similar to the small Admiral sets. The real nice ones sold for $40.00, two bucks more than new.  |
My Kenco portable lasted all of three years and worked quite well before something shorted out in it. I turned it on one afternoon and saw a wisp of smoke coming out of the ventilation slots in the back of the cabinet. I junked the set almost immediately after that and, the next day, bought a solid-state 12" Zenith b&w portable at Best Buy for $62. That set lasted 22 years and was still working amazingly well, bright picture and all, when I got rid of it in 2000. I'd have kept it, but I had just moved to my apartment a few months earlier and had no room for another TV, as I had brought two color sets with me from my former residence.
I hope whomever snagged that portable from the trash got a few more years of use out of it, as it was far from useless in its condition at the time. In fact, the only thing wrong with it was that the detent mechanism on the UHF tuner was jammed, freezing the tuner on one channel. If that set is still in use today, the broken detent wouldn't matter anymore since the set would have to be used with either an OTA converter box or a cable box, of course, which normally output to VHF channels 3 or 4.
BTW, I didn't know the Kenco portables sold so cheaply when they were new. I don't remember how much I paid for mine in the mid-'70s, although I seriously doubt it was more than $50 or so. (I didn't know at that time that these sets were leaders; if I paid $50 or more for mine, I'm sure I wasn't aware of that fact, or else the store I bought the set from wasn't aware of it either.)
I had the back off the set at one point and saw just how cheaply it was built. Every tube, including the horizontal output/damper tube (38- or 53HK7, IIRC), was mounted on the set's single large PC board. There was no metal chassis; the entire set, except for the tuners, speaker, volume and contrast controls, was on that board. First TV I ever saw with almost the whole thing on one board. Was this a glimpse of what was to come in later sets, before they all went solid-state?
My Zenith 12" solid-state b&w portable was all on one PC board as well, except of course for the tuners and controls. It probably made sense to build a solid-state set on one PC board, since these TVs run much cooler than the tube-powered ones did. In fact, the only transistors in a solid-state TV that heat up to any extent would be the horizontal output and, perhaps, the audio output. The rest of the set could and probably did run as cool as a cucumber. I don't remember my Zenith SS portable ever getting as warm as some of the old tube sets I've owned, and I used that set a lot.
Today's flat screens, 19" and smaller, run much, much cooler and draw less power than most if not all SS CRT sets, although I have read here that the very large flat screen sets do heat up quite a bit, and draw quite a bit of power to boot. Someone here on VK (miniman82 comes to mind) has or had a DLP or projection TV that draws something on the order of 500 watts, but that's par for the course for a projection set, at least the older ones. The newest DLP/projection sets, if they are still in production, are likely designed for much less current consumption, and could be Energy Star certified as well.
