I just bought some nos 300b tubes - however they have 6 pins in base - and I need to fit them into a 4 pin socket... Never navigated this issue before. Is it possible to buy a convertor? Or is there another way? All help much appreciated. Best wishes.
 
Welcome to the forum.


Are you 100% sure they are 300B tubes? Are there any markings on the tubes? What brand? This does not sound right.
 
I have never heard of a 6 pin 300B. I think you got hosed and I hope you can get your money back.
