So the first JJ GZ34 failed after about 6 months. I replaced it with a Sovtek and it lasted about a year. This is acceptable because I use it daily so they can be expected to fail at some point. The last Sovtek I put in lasted only two weeks! This is getting annoying. Are there any reliable newly manufactured GZ34s that anybody knows of? Anybody else have problems with these failing very soon?
I am using a 33uF for the first cap, 1.5H choke, followed by a 120uF cap for the input of the power supply.
Edit: The first JJ actually lasted almost 6 months, not 2
