Hi Gang,
Came into the office this morning and turned on my Dynaco Stereo 70 clone with Shannon's board and the GZ34 rectifier I have in it flashed over and blew the primary fuse. It's a new JJ version of that tube that only had about 150 hours on it. This is a brand new amp I built from scratch with a new chassis and Uncle Ned's transformers. It has the standard size electrolytic can cap (new) so the tube was not working into capacitors that are too large.
Seems like I read somewhere that GZ34's aren't all that great and fail frequently during startup surge currents. Any comments on that? I have several old 5U4's that I'll put in there next. I'm quite sure they are much more rugged. The only problem is that my spare fuses and tubes are at home so I have to listen to solid state today. Heresy! :-)
Best regards to everyone!
