5AR4/GZ34 Rectifier Tubes

Geoffkait,

They were manufactured by Bugle Boy around 1952 and have three holes in each plate verses two in typical tubes and sounds phenomenal, a great tube and a good find...

A little clarification. The "Bugle Boy" was a series of tubes that were made by Amperex. There was no company named Bugle Boy.

Mofimadness,

Thanks for catching that; more reading material

Wig :o)

I believe Wig is thinking of Sylvania Bad Boys

Iso...nice catch on your part also! Wig is indeed thinking of the Bad Boys since he was using VT231s which are a 6SN7 substitute. I can't believe I missed that. I actually have several pairs of Sylvania Bad Boys. Great tube btw...
