I bought a BK Precision 1660A Triple Output DC Power Supply | eBay[^] off ebay for about the same price about 10 years ago. It had come out of a lab so no telling how old it was.
Yesterday I'm working on a project, turned it on and the lights flashed for a uSec and damn no power. Took the fuse out and sure enough it had blowed. So who sells fuses anymore? Checked with the local home improvement stores in the 2 nearest towns and there is 1 fuse at one of the centers. Problem is that they don't update there inventory and I've spent whole days driving many miles because they said they had something but turns out they didn't actually have it.
I ordered fuses off ebay but it probably is another issue, the service manual says that unless there is a more serious issue they don't blow fuses.
I got a lot of use out of this power supply but it's probably time to put it to pasture. There are things that I didn't like about it so my SO offered to buy me a DP900 HIGH PERFORMANCE LINEAR DC POWER SUPPLIES | RIGOL[^] for my birthday.
I'll probably try to repair the old one and keep for backup.
Right now I've got a ton of projects and there's very little I can do without a power supply.

Have you checked on DigiKey[^] or Mouser[^]? That's where I usually go.

Yes I get quite a bit of stuff from both.
Part of the problem was size, my bench is a set size and the supply I'm getting fits, most of the others I looked at won't fit in the slot allotted. I've been looking at supplies for about 6 months, I knew the one I had would go out eventually.

Sweet supply, Mike! That SO is definitely a keeper!
Somewhere around here I've got a Heathkit 0-15V dual power supply I built in the 70s. If I ever find it, I wonder if it will still work?

Yeah it's been a real work horse, I hate to replace it but it's time.
Coincidently the one I had prior to this one was a R175921 Heathkit IP-2718 Tri-Power Variable Power Supply | eBay[^]. When I upgraded to the B&K I gave it to a friend of mine that was just getting into electronics. He's had it for 10 years and as far as I know it's still truckin.
Back when they built stuff to last!

I had a large 300w air blower go out recently. It seemed like a solid build, but then I noticed that there were a few lead wires that were aluminum. After running 24x365x a few years, the aluminum had oxidized away. I replaced the leads with a good copper wire and it fired back up.

I think it was in the 70s they used to wire houses with aluminum and it was not good.
When I did remodeling I would run across a house that was wired with aluminum, very rare now a-days.

Gold wiring is the best.

For electronics contacts - yes. Even if it is available, I doubt whether many of us can afford to wire their entire house with gold wiring.

Actually, silver is the best conductor.
But gold has the advantage of being more durable due to
its high resistance to corrosion, tarnishing and oxidation.
So for critical connections gold is the preferred conductor.

Yes, long time since I heard this.
Thanks.

The AL wire wasn't the problem. The problems were not being aware of the importance of anti-corrosion measures (especially when joining Al and Cu) and the need to enforce a torque spec on all screw down connections.
AL has always been used without problem for heavy gauge feeder lines, and if connected properly is perfectly safe for standard outlets and hard wired devices. The initial standards for using it with 15/20A circuits was just 🐘💩.

I imagine, given the age and solidity of your supply, that the first thing after the fuse is a hefty transformer. Unfortunately if there is a short on the primary (or even secondary) then getting it rewound is going to cost more than your car.
An alternative point of failure (and hopefully more probable) is the rectifier bridge(s) after the transformer. That should be a very cheap fix.
Time to get the ohmmeter out!

My mind immediately though "hmm, you could be onto something..." the danger if the transformer insulation is going is fix it in one place it will pop in another, a possibility I can't lay hands on the link but there was an eBay seller who had a lot of spares for Heath-Kit, Crown and others. Mind you the thing is 'To fix the fault that caused the fault'.

I was thinking more along the lines of a small thermonuclear device.

I'd be happy to load you up some fuses, Mike, but primers are awfully expensive and rare right now.
