I have an ANK kit 1 300b set amp that I just built in November.
After about two hundred hours of use and incredible satisfaction, the rectifier tube started to spark upon start up.
Then it started blowing fuses. I was guided to try a replacment rectifier tube (5v3).
I bought a pair and each worked for a little while, but then they started to do the same thing.
Now I have been guided to try a 5u4g type rectifier tube.
I built this amp to go with a set of high sensitivity speakers I built for myself last summer.
It replaced a ss amp I used to use (audio upgrades modified- 1985 Adcom 555).
It's a bummer because I love this new SET amp so much.
It smokes my old Adcom, making it sound etched and grainy in comparison.
I have since switched back in my Adcom555, but it pales in comparison to the degree that I have prefered to not listen to music at all.
I will do anything I can to get this problem rectified (pun intended)!
