@whart thanks for the guidance. I'm a bonehead and step 1 should have been to check the fuse. Blown. Replaced and back up and running. Testing out a Brimar 5V4G. I'll be following up on your H-3000 threads and guidance. I've heard stillpoints and tube rolling, any advice on cables for the power supply?
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?

Frankly, I should have suggested you check the fuse. As to power cords, try several and see what you like. There is something to be said for "same cable" throughout a system, though that means you could miss by a mile too. I found very little benefit to rolling the audio tubes and those on the main chassis-- I went with Dutch tubes as I recall when I recently retubed. The rectifier is key to this thing, though. And you’ll hear different things from different people which means a number of variables: system voicing, where the system benefits from the particular tubes strengths and minuses--as well as shortcomings in other parts of the system. Mine currently gels but I think this is very system dependent, based on personal (and hopefully informed) preferences. BTW, is the tube you are focused on-- apparently a GZ32 equivalent-- the correct tube for this power supply? |
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. https://gestalt.audio
OR one of the models made by Zavfino https://zavfinousa.com

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.
