Well Alan, guess I will start this new section of the forum.<BR>My interests in antique TV's are mostly the sets made before 1950, but I must say I have several "modern" sets, several LCD pocket TV's, three 5" B&W TV's, one JVC 5" color TV/Monitor, about a half dozen 1960-1970 vintage sets not working, I even have the chassis of the 1954 RCA CTC-4 color TV with most of the inportant parts still in it,ex: flyback and power transformer, etc., though I stripped out the caps I put in it years ago.<BR>Not too interested in color TV, they are way too big and heavy for this old goat to carry up two flights of stairs to the attic workshop, I like the real small suitcase type sets, besides I always had a thing for small screen TV's.<BR>Speaking of small screen TV's, I live near the city that made the "Temple" television, it was made in New London, CT. about in the late 1940's, does anyone remember "Templetone"?<BR>A good friend of mine here in New London can give you some history on templetone, they were not a good set, the power transformer was undersized and they used it for BOTH the low voltage and high voltage, all in one transformer, I beleive the model of the set was 1776,they went out of buiseness after they made that set, my friend Bill knows more about it than I do, Of course it was before both of our times.<BR>Anyway, I think I took up enough of your time on this, hope someone out there will remember "Temple" TV's and "Templetone" radios.<P>Bill<P><P>------------------<BR>

I do like to see a special corner tucked into this great forum in honor of tv sets . <BR>I dont actively collect tv sets but they were a HUGE part of my younger years . my very first job out of high school was going up to a thrift store in the evening and fixing all the tv sets that were donated . this was mainly in the late 70`s . i fixed literly<BR>thousands of tube tv sets .<BR>today i own one 21'' Philco Predicta holliday in blond with a bad pcture tube of coarse ! and a small Motorola 1950 dark wood round tube table tv set . it works but needs those high voltage deflection caps. repaced .<P>ken <P>------------------<BR><BR>

Ken,<BR> If you need any .0047@8KV, I know a guy who has NOS .75 each!,I used them in my Pilot and Motorola VT71, they are very good.<BR> I do not have his web address handy, but it is Mark Hannah surplus Electronics,<BR>I can get the address if interested.<BR>Bill<P>------------------<BR>

Thanks Bill <P>I replaced the filters with nos cans and that fixed that . it still runs on those old caps but i dont trust it .<BR>My plan is to just get rid of it this way so dont worry about the caps <BR>ken<P>------------------<BR><BR>

Hi Bill and others,<BR>It is interesting that you mentioned the Temple tv's using a power transformer that had both low and high voltage in the one unit. I am assuming that they incorporated both tube filament and h.t. windings. <BR>Nearly all Australian b&w tv's used this method (there were a number of transformerless sets as well ) but the hefty transformers used were more than adequate for the job. <BR>In some of the earliest tv's, there was a 5v winding for a 5U4/5AS4 rectifier as well as a 6.3v winding for everything else.<BR>If the tv wasn't worth fixing,we would take out the power transformers,turn them into 6v and 12v battery chargers and sell them.<BR>Regards,<BR>Ron. <P>------------------<BR>

Ron<P> We call low voltage the B+ winding in a TV. A few early TV's didn't use a Horizontal Output Transformer to get high voltage for the CRT. Instead the power transformer had an additional winding for this voltage. <P> Most very early TV's used power transformers. Some even powered dual 5U4G's.. In the 1950's two selenium rectifiers were used in some TV's using a voltage doubler circuit.<P> The Temple TV-1776 only used 17 tubes and didn't have a high power horizontal output tube.. It used a 1B3GT, 5U4G, 3-6AK5's, 2-6AL5's, 3-6AU6's, 2-6SL7GT, 6SN7GT, 6SQ7GT, 6V6GT, 12AT7 and 7JP4. <P> Sorry Doug, I removed the DC. Been talking radios too long.. <P>------------------<BR>Norm<p>[This message has been edited by Norm Leal (edited 08-21-2000).]

Actually, a vcoltage doubler is an AC-only circuit, and won't work on DC.<BR>True that some early sets, even postwar, didn't use the flyback High voltage supply. The Philco 48-700, I understand, used a "hard' power supply, which was a HV winding on the power transformer. Of course, the prewar sets also had hard power supplies. The one in my RCA TRK-12 puts out 7300 Volts for the 12AP4. Approach that one carefully!<P>------------------<BR>

B&W TV started at the end of 1956 in Australia just in time for the Melbourne Olympics.<BR>There were no electrostatic deflection commercial sets produced, they all initially used 17" magnetic deflection tubes with flyback horizontal scan stages and flyback EHT supplies (except for Admiral who used 21" tubes from the start). Power transformers were almost universally used except for a very few exceptions (the English Ekco and a 14" Astor being the only ones that come to mind in the early years). There were no mains EHT windings used.<BR> Don Black.<P>------------------<BR><p>[This message has been edited by Don Black (edited 08-21-2000).]

Hi Norm,<BR>Thanks for the enlightenment on power transformers in early tv's. As Don has mentioned, by the time Australia got around to television, all the sets we saw here had HOT's.<BR>Ron.<P>------------------<BR><p>[This message has been edited by Ron Pond (edited 08-22-2000).]
