Hello everyone- just finished a Mojo 5e3 kit and wonder what you guys are digging in the rectifier dept? The amp doesn't have a STANDBY switch so i'd like to use a rectifier with an indirectly heated cathode. I'm currently using an NOS 5y3 with JJ 6v6s, which gives me 376 VDC on the plates. The stock sovtek 5y3(?) gave me 406 VDC on the plates, and a new JJ 5AR4 gives me about 412 VDC. Will the JJs handle this OK? I noticed KCA has some NOS 5y3s with indirectly heated cathodes(I've never heard of these before) - has anyone had any experience with these? The amp sounds great at 376 VDC, but being my first build, i'm a little reluctant to run it hotter without some advice!!
