howard radio
I went to a flee market and found a howard radio that I'd like to buy. I'm not sure what model it is but it does have a tuning eye so it should be late 1930's. Its a table top and it is kind of rough but for ten dollars I am not too worried about that. I noticed when I look in the back that one of the speaker wires has been pulled out of the output transformer. Ok, I have gently peeled back the paper on one before ,found the wire and just soldered a new one on and was back in business.If this one is not that easy what kind of hoops will I have to jump through to find another one?

On a early 50's majestic TV that had a blown audio output Xfmr. I just replaced it with a similar sized unit that came from a amp from a cheap Deca HiFi phono console I junked, and it works just fine like that.
A generic replacement or a junked part should work fine.

I thought an output tranny was a little more of a specialty item. At Fair radio they have a box of the same size rca speakers with the trans. on them, so I will just grab one of those and mount it. Ok, I did not know it was that easy. Thanks. Oh, One more question if I may. because of price I have been subbing 5y3 rectifier tubes in my radios instead of 5u4 tubes. Is this a mistake?

It used a three tube amp for stereo, no tuner, dual volume knobs instead of volume and balance, puny speakers ,and an earlier version of the changer in that Arvin you were surprised I used to play records in a Goodwill. I have no clue what it originally sold for, but from scrapping it I got the feeling that it was cheaply made (I could lift it with one hand). This thing gave me the impression of a good sounding cheeply made table model's electronics stuck in a console for the heck of it.

The 5U4 is rated for somewhat more current than the 5Y3. So look up the tube to find the allowable current and compare it to the load in the set.
Of course, if you aren't a purist, a couple of 1N4007 diodes (for pennies each) and a resistor will substitute just fine in almost all cases.

Those 5Y3's are probably going to have a reduced service life doing the job of 5U4s.
Think I'd go the silicone diode route before straining a 5Y3.

The same.... broadcast and sw. Its rough but I still like it. the metal dial has rust where the painted numbers used to be.the rest of the dial is clean and shiny. The cabinet is in one piece but needs a lot of tlc. I will post pics when I get home. I always liked a set with an eye tube. Kind of makes it stand out when running
