I have a Mastech HY3005 power supply (ex military). It's kind of cute. does both constant voltage and constant current and could be used for plating, etc.
It seems to be fine, except that it is missing a fuse. I tried puching in a regular Buss fuse and it would not fit. I think that it uses some smaller fuses, not sure what kind.
So... What are those fuses that are slightly smaller than regular little Buss fuses sold at Ace hardware etc.
thanks
i3/8 inch ?

There is a 5 x 20mm variety. Radio Shack sells them if you can't find them anywhere else.

Let's say that I go to some store or try to look up those fuses on the web, what should I ask for? "Do you have 5/8" fuses"?
The power supply seems to work if I insert a nail in the fuse opening, but, obviously, it is not a good practice to use it that way.

Sounds about right, I will try to check out RS. Thanks.

There are also 5x25 & 5x30mm fuses. Not as common as 5x20mm, but check to make sure before you go shopping. If you have trouble finding them locally and/or aren't in a hurry, email me the amperage and if I have them I'll stick a few in an envelope. I used to use a lot of 5x25mm in control panels in modular fuse holders, but these days I can buy circuit breakers for only a few dollars more than the fuse holders.

Thank you Ned. I already went and bought 5x20mm fuses at a nearby RadioShack. I will try them tonight.

old number was probably an 8AG unless they were the foreign type.

Thanks to all. I really needed 5x20 fuses. The ones I got yesterday were wrong size, but the power supply shows healthy signs of life.
