Allnic h-3000 power supply issue


I've been using my Allnic H-3000 for about a week now with no issues. Fantastic experience. Well I just went to swap the tubes from the Shuguang 5z3p to the Brimar 5V4G and now the power supply will not start up. The unit was unplugged when swapping the tubes and once swapped I turned the unit on and it illuminated. I went to put the box away and turned back around and the unit was off. 

 

Swapping the tubes back made no difference. I tried a different outlet and no difference. Any ideas or guidance?

I understand ya. Did you have any luck with any cables? Anything you did or did not like? I'm currently plugged into my Ps Audio P10 so I'll be experimenting with this and direct to the wall as wall. 

 

Im currently using a NOS Brimar GZ32 and have the Shuguang posted above as well. From what I've heard it can run a GZ32, GZ34, GZ37, 300B and Im sure a few others. 

As far as power cords are conserved, I’d recommend the Hijiri Nagomi made by Combak Corporation in Japan.

j-wall glad to hear you solved your issue.  Good advice from Whart as well!

I rolled the stock power tube on my h3000 with a NOS Mullard years ago and got a huge bump in performance in my system.  Frankly, I was shocked that it could make such a difference.

Good luck with your journey with power cables - I also believe the same brand should be used throughout.  I have tried an embarrassing number of IC/SC but not a lot of PC’s.  I have stuck with wywires for all components and have been pleased.  I also plug everything into a Shunyata Denali V2 fed buy a Sigma XC PC.  This was also a big bump in performance in my system. 

 

@pops thanks for the advice. I've definitely got a mixed bag of AQ and Shunyata cables. I guess I'll just dive in and go for it. I think I read Albert porter was a fan of the stillpoints so I'll be dipping my toe in that realm first. Also, which Mullard did you try out and like?

@j-wall I am using 5AR4 GZ34 big base Mullard.  It was such an improvement in an already great presentation that I stopped there!  Albert’s great - that is where I got my Allnic h-3000 and also various PAD cables.  Can’t recommend him high enough.
