We perhaps drifted a bit off the subject of old TV's but there have been some good posts on that subject too.

BTW, what is the deal with the voting for a thread, I have voted on some but the only ones I see that has ratings are the "Show us your..." threads?


<tv content> The transformer in this GE I'm working on seems to be shorted, I removed it completely from the chassis and powered it up through a 150 watt bulb and the bulb lights brightly, an amp meter shows a 1.00 amp draw with no load? (using the bulb)
The Sams says it's 2 ohms across the primarys which is pretty close so maybe I have a shorted secondary?

I don't have the nerve to hook the trans directly to line voltage and see what happens, perhaps I will take it to work and do that, blow their circuit breakers and not mine.

Usually I can power an entire set up with the 150 w bulb.</tv content>

Eric,

If you have removed all secondary loads, i.e. tubes that use the filament windings, the rectifier tube, that uses the HV winding and can light a 100 watt lamp in series with the AC line input (primary winding) you either have a short in a socket on the chassis somewhere, or your transformer has a short inside. If it is the transformer, remove it from the chassis, take off the end bells and perhaps you will be able to find the short. For testing purposes the series lamp is great. You can also place 120 volts across the HV B+ winding and the transformer will be less stressed if there is an internal sort. If the xfmer is good you would read a voltage on the 120 volt primary winding which is equal to the step up ratio of the 120 to the HV. Maybe about 120 volts divided by six, or 20 volts AC, if the primary is good.

You really should have posted that question in the "My GE has a shorted power transformer forum"!

All,

I'm going to stick this thread to the top of the line and re-name it. It will be our own TV forum general discussion thread. Topics do not have to be TV related as long as they are posted by someone who have themselves, or personally know someone that has seen a TV, preferably of some vintage. Until I get a round tuit, please continue to post off-topic discussions here.

I do not know how one rates a thread, or where our 5 stars came from. I don't think those stars is anything bad though.

Thanx all for great conversations and posts.

Rob
