My name is Doug Mackenzie. I found the CVRS web site a few days as I was looking for tubes for my old radio. My wife and I moved to Manitoba from Bc a few years ago. I have had a 1931 Echophone Model S-5 8 tube Cathedral radio for almost forty years. We had professional movers pack and move our belongings to Manitoba. I didn’t unpack the radio till this summer. There were three missing tubes and one broken; I guess I’ll never know what happened. But now I need to find some tubes. I’m hoping someone here can help. The tubes I need are , 280, 227, and two of 245. It would be great if there were someone in Winnipeg that had these tubes as I would like to get the four tubes I still have tested.

Welcome to the forum Doug !
glad to have you aboard.
The Echophone cathedral is a goregous radio as I recall, I hope you get this sorted out.
I didn’t know if you are an avid collector so forgive me if this is too basic.
– the 280 is a rectifier. the first number relates to the manufacturer so you may also find 280 or 380, perhaps others. it is an 80 electronically. an 80 is probably the most common rectifier for radios this age. a tube designated 80 is more common and will have the ST envelope (coke bottle shape) you will probably pay less for an 80 than a 280 because of it’s scarcity. the difference is wheather you see the pretty globes in the back of the set.
227 or 27 same thing, 227 is a globe 27 an ST. this is a pretty easy to get tube. some TRF radios had a bunch of them so they seem more common than the others you want.
The 245’s – or 45’s are expensive. There has been a trend with custom amplifier builders to drive the prices up on these. The danger here is that most of the beautiful cabinet radios made about 1929 use these tubes, so this activity is a thorn in the side of those who would like to see every remaining set restored and working. this tube is not that uncommon and you will find them.
If I moved that radio. I would be sure to remove those globe 245’s to prevent breakage, hopefully they put them in another box for safekeeping ?
So when you find a source, you will have a choice of either more expensive but beautiful globe tubes or ST shaped tubes which will perform just as well if you aren’t concerned about the cosmetics or if you play the radio a lot. There are some tube dealers that you could buy them from , hopefully someone local can assist.

Doug – I just wanted to pipe up about the 45’s – they can be expensive – however – the audiophile guys are looking for new old stock or ones that test high for mutual transconductance – you can find ones on ebay that test a little low – (and buy from canadian sellers to keep the shipping low) the audio guys won’t buy them – hook up with someone who has an emission type tester and get yours tested – I have had tubes that tested as low as 30 or 40 percent that performed fine in a radio – its more important for your radio to have two that test about the same – the tube before the 45’s – called the driver tube or 1st audio tube needs to be strong in order to properly drive the two 45’s – the other tubes in the set are common – they shouldn’t be hard to get.
