Westinghouse H-104

Gotta love a good westy , 5U4 and a pair of 6Y6's ... too cool .

I got an FM console version here , the Westinghouse H114 , 14 tubes including the tuning eye , the 6Y6's are in push pull , and not one but two of my all time favorite tube , the 6H6 dual diode (the tube that the 7 pin 6AL5 is based on) . With 14 tubes you just about could heat the room with it , and just for grins , look up the heater current of the 6Y6 , it's higher than any of the 6L6 6F6 6V6 output tubes , 1.25 amps VS the 6V6's .45 amp ! This explains the rather large power transformer and 175 watt input power rating for the H114 .

Wow! I didn't know that Westinghouse was indeed sort of like a DuMont as far as building higher end stuff with a bit of really cool electronic overkill. I'm glad now that I started this thread. I personally never owned much by them in a radio. I've seen more 50s TVs and the same period and later kitchen appliances. I do have this older model Standard/Shortwave with the all mighty "magic eye" that to me is really cool with most of that periods bells and whistles. It only needs a dial string.

So both of these are in very good playing condition without restoration. I love that phenomenon in electronics. The total survivor one might say. Heck, when any piece of electronic from the 1930s can stand working today with only a piece of string as needed repair; you can safely call it a survivor and a well made product.

Very nice ! One thing I want to call to your attention is , both my H114 and your H104 have resistors and capacitors built into the IF cans , and those gave me a bit of grief when I restored mine . I had replaced all the under chassis caps , checked and replaced all out of spec resistors and the performance was still only marginal in my opinion . A closer look at the schematic revealed the components inside the cans and when they were replaced the set came alive . With only it's internal antenna there were literally hundreds of standard AM broadcast and Shortwave stations to be heard . The FM works mostly OK , the stations it gets are plenty good enough sounding , it just don't receive as many of em as other tube FM radios I own , like my Zenith 8 tube table model for instance .

So , looking at your H104 , I see the RF transformer contains resistor R26 inside it , your second IF transformer contains R25 and C39 and C40 . These components are in addition to the usual two coils and two capacitors regularly found in RF/IF cans and can be easily missed , as I did , when troubleshooting lackluster performance .

The 6Y6G, 6Y6GA is a low B+ beam power penthode, that is in the same family as the 6W6GT, 6DG6GT and a few others like the 25L6 and the 50C6G.
GE used them in a few models of pre-war radios in push-pull configuration. They can only take a maximum of 200 volts or so, plate and screen.
I really don't know the advantages or disadvantages or this type tube. I leave that to the engineers.
