Hi all
Well ok this thread is not about a tube amp, but I guess it might be the right place to get in contact with other HSPY 400-01 users, as it is very useful for diy tube amp creators. With its 400V 1A and approximately 250$, it suits perfect for tube lab projects!
One of mine did so for close to 3 years, but the last time, it took several attempts to release output. And since some days, it strikes totally. When turned on and released, in changes immediately into "CC" current limit mode, but no voltage at all is provided.
Does anybody experienced similar behavior?
Is there any chance to repair it?
Does somebody own a schematic?
Thanks for all hints!

Hi,
Did you find any solution for this?
It seems like i had same issue today 🙁
I opened the device to short the MAX232 to let it work with TTL-USB adapter.
I managed to get that working quite easy, but now the psu will not give voltage out 🙁

Hi Rapzak
No, unfortunately I failed to repair my defect HSPY 400-01.
I guess it was a „Monday morning sample“, rather than a systematic design issue. Because my other two work still fine, since about 5 years now.
