Posted by FenderLover on 2007-09-21, 06:36:54 (24.205.135.213)
Jim, I have had Bendix both labeled 6106 and 5Y3WTGA. Both had same internal plate structure. Both BP with a tan/brown base. Anyhow, I only have a 6106 in a unit, at the moment (Fender Champ SET amp) .......

"I have had Bendix both labeled 6106 and 5Y3WTGA." I've also seen them labeled 5AR4, believe it or not! But I meant a properly labeled tube. The 6106 isn't a 5Y3WGTA any more than it's a 5AR4. "The .......

Right, the 6X5 is 6 volts. I was more making the point that the 5Y3 and 6106 were very different in construction and that the 6106 was constructed more like a 6X5 than a 5Y3. I was not heading down th .......

Forget the switch. Why not just use a slower start-up 5V rectifier like a GZ34 or Bendix 6106 (although I don't necessarily want to drive up the cost of 6106's by recommending them to others)? I find .......

Your point was a good one. And it also indicates that a 6106 is indeed a different tube than a "real" 5Y3WGTA - or the voltage would be unchanged (or just a very small change). .......

The 5Y3GT/6106 will need 5V/2A and the 6SN7GTA's will need 6.3V/.6A... Seems logical to keep them all separate. Would this be going to far? Or would this be a step in the right direction? Do they even .......
