What is the best place to buy vacuum tubes? Anyone have a slam dunk tube supplier in the USA? I still have a number of machines that still have vacuum tube circuitry. I have kept a couple in stock for years and now I'm at a point of control upgrade or just find some more spares.



Is there a best place to buy vacuum tubes? Or just check on Ebay....

Hello Roundtable,
Guys I have a newer pacific hydraulic press with NC style controls. I have a recurring power supply failure and i'm looking for some advice.

It is a 3.5 amp 24VDC power supply. Fuse didn't blow the on the original supply. So I assumed it gave up and ordered another one. Turns out about two weeks later same problem came back, no 24V again.

I checked the power supply and found a good fuse but no output again. I thought they maybe sent me a bad one and I made the mistake of ordering another one and same thing happened. 3rd one has failed and i don't understand if it's not being overloaded what could be going on...

Any thoughts on my recurring power supply failure?
