Crosley 828 Transformer replacement.
 
I was given a crosley model 828-M floor model radio from 1938 for Christmas.
I brought it up slowly on the Variac on Christmas day. I got a horrible, smoky smell from the power transformer and the 5y3 heaters were very dimly lit. Checked the power transformer voltages on the socket of the 5y3 and they were all wrong. I just now have the time to restore this radio due to previous projects. I am trying to source a new power transformer replacement and think I may have found one but I would like to hear from the folks over here at VK. I stumbled across a thread on antique radio forms mentioning that this model uses a 350-0-350v transformer. This is what I think will do the job https://www.tubesandmore.com/products/P-T273DZ Is this a suitable replacement? I have done some investigating around the radio and the replacement seems to be correct. Your thoughts?

Looks like a good fit to me, 5V @ 2 Amp, 6.3V @ 3 Amp and the 350-0-350 @ 100ma.

:) Hi Swizzyman ,

For $103.52 before shipping (the cost of the linked transformer) , I'd git my butt to one of these swap meets the guys are always talking about and buy up a whole trunk full of radios to take a transformer out of . On a cost VS value basis nothing would beat grabbing some swap meet radios , just make sure some have a 5Y3 in em and you'll be all set , that 350 0 350 , 6V , 5V transformer has gotta be the most common one used in parallel wired sets .

And then think about all the nice leftover parts you'll have to go into other projects . In the grand scheme of things , does a 78 year old radio really NEED a brand new transformer when used = pennies VS dollars ?
