changing a 5Y3GT tube for 5U4GT (Read 3139 times)

nico Senior Member Posts: 94	changing a 5Y3GT tube for 5U4GT 08/06/11 at 08:05:53 Not familiar with tubes yet.... My Zen came with the 5Y3GT rectifier tube, and some spare tubes including a 5UGT. Info on the net says they are the same, but pin-layout is different. When interchanging these tubes, do I need to alter wire- hookup on the connector? Thanks, Nico

Forgot to say Thanks! Wink

By now the riddle of why the 5U4G did not fit at first, is solved. [wrong transformer mounting].
I read alot about the MULLARD GZ 32 , anyone here who can tell the difference between my Sovtek5U4G and the Mullard?
Does changing the rectifier really make such a difference in sound?
Any comments are appreciated.
