Can I use 6x4 instead of chinese 6z4 for rectifier

They are both tube full wave rectifiers but they are not wired the same. You need to change a couple of wires. I was looking at a supply this past weekend that used the 6z4 and the 12at7, 12B4A. I asked if it could be switched to the 6x4 and the said yes. I can send you the data sheets if you need them. One is in Chinese though! I have some NOS 6x4's so I was also interested in doing this. Let me know how it turns out.

Here is some specs of the net.[http://www.shinjo.info/frank/sheets/095/6/6Z4.pdf][http://www.shinjo.info/frank/sheets/127/6/6X4.pdf][http://www.shinjo.info/frank/sheets/127/6/6X4.pdf]

On EBay there are now several adapters .I bought a 6x4 to 6 z 4 adapter just plug in and you now can use the much better 6x4 there are now many choices.

Thanks Audioman58 I will likely give that a try

I too have used an adapter allows me to use 6X4 rectifier tubes in place of a 6Z4 tube. I just had to modify the tops of my preamps to handle the extra height now of the tubes. I really like the 6X4 tubes in place of 6Z4. Lots of choices to be had.
