I have some material from a NRI radio repair course that my father took in 1937 and there is an article on telvision sets in one of the magazines that they sent to their students. The article has pictures of happy families sitting around the living room looking at sets that look like console radios with little round crt's in the top centre. The most interestin had a larger crt that pointed straight up and you watched it through a mirror on the bottom of the top cover that was tilted up at a 45 degree angle. There is a surprisingly large amount of material on televison in that course and none of it was any use to the old man because television didn't arrive in his area until 1951 and he had long since given up radio repair for farming, marriage, and children. -- Richard Loken VE6BSV, Systems Programmer - VMS : "Anybody can be a father Athabasca University : but you have to earn Athabasca, Alberta Canada : the title of 'daddy'" ** richardlo@admin.athabascau.ca ** : - Lynn Johnston ------------------------------ From: W0EOM@aol.com Message-ID: Date: Tue, 13 Feb 2007 12:17:04 EST Subject: Re: TV, etc. & P Farnsworth To: Old Tube Radios MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="-----------------------------1171387024" -------------------------------1171387024 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Marty - i am presently reading the book 'The Boy Genius and the Mogul', the story of Farnsworth and Sarnoff.

The schematic and parts list doesn't give the Henrys nor the resistances. I've had both chokes rewound and one is 15 Henrys and measures 190 ohms on a Eico Model 221 VTVM. The other one is 35 Henrys and measures 1000 ohms. My Sencore "Z" meters only measures to 10 Henrys so no luck there in confirming whether the chokes are still good. Problem is a loud hum or horn sound and the three 10 Mfd. 450V condensers all come thru with flying colors on both the "Z" meter and the N.R.I. R/C Tester. My next effort will be to substitute another audio output transformer (for the original in the rcvr). I have the one I salvaged from my first 129-X which I parted out a couple of years ago. I am still open to any ideas or suggestions. I am too stubborn to give up!

A low emission tube almost never adds hum either. It actually would reduce ripple by increasing ESR from the transformer. Now a shorted tube or a full wave rectifier with one half dead could increase hum, but from all the problems you described I'd say the filter capacitors are bad. Just MHO. 73 Tom ------------------------------ Message-ID: <004001c75085$aaa39c30$32e47443@KB6NAX> From: "Arden Allen" To: Old Tube Radios Subject: Re: FW: Resistance values of power supply chokes.

I'd do those before doing anything else to it. I'll second that. If you don't have a way of measuring ESR and before disconnecting the 'lytics there are two ways to make quick checks. 1) Bridge the suspected cap section(s) with good caps of approximately the same capacitance. 2) If you have a scope look at the ripple on the cap first in line from the rectifier. If the wave form is **humpy** you have high ESR. If the waveform is nearly a perfect sawtooth the cap section is good. Go to the next stage of filtering to see if the sawtooth has been dimished to a sinewave like waveform of much lower amplitude. And so on....

If one half of a full wave rectifier (5Y3, 5U4, etc.) goes flat before the other half you would get 60Hz ripple instead of 120Hz ripple. That, in addition to causing lower B+ voltage, could produce audible hum. You should know the difference between the way 60Hz and 120Hz sounds. Usually rectifier tubes wear out both halfs at the same rate and B+ just goes way down.

Yes, gravity is Simpson's worst enemy. But don't give up hope. Try getting a new case from other meter service outfits. If a replacement case can't be found epoxy is not a bad way to go. I've repaired my Weller soldering gun a couple of times with ordinary (not the 5 minute stuff) black pigmented expoxy available in hardware stores. A paste type is not necessary and even may make fitting the pieces together more difficult. Clean up the squeeze out with a cloth dampened with acetone or toluene after joining pieces. Bits of masking tape can be used to hold pieces together until the epoxy cures. Give it a good day to cure at room temp.
