Western Electric 300b Tubes - Differences

Aha, awesome info. Bander, eagerly awaiting the result of your research!!

Pawlowski, I'll get back as soon as possible.

OK here's the real skinny on the Western Electrics. I just spoke with Charles Whitener at Western Electric. There is no such thing as an OEM tube. It's a term that's being bantered around. If a 300B comes in a blue and white box and there's no seriel number on the tube itself, it hasn't met specs and is a B stock tube. The people at Canary Audio had been buying these tubes from Western Electric. I recently paid big money from a guy who has been getting them from Canary and selling them. Mr. Whitener and Western Electric is no longer providing these inferior tubes to anyone. These are now being discarded. Stay away from any seller who has 300B's without seriel numbers. They are bad news. What an expensive lesson I learned. I'm still nauseous over my loss.

Good info there Bander. Thanks mate. (Sorry for your loss).

Regards,

Awesome, thanx. Bander, I hope you weren't too badly. Did the tubes you buy sound poor?
