Mallory Recto Power supply

[tweak]

I have a really old benchtop power supply, an Mallory model 12RS6D
6/12 volt power supply.
When I dug it out of storage I noticed the cap to the fuse holder as
well as the fuse was missing.
Does anyone here know what rating fuse this unit takes?
I tried a web search for Mallory with no luck.
I can post additional specs on this unit.(volt/amp rating etc...) if
needed.
Thanks in advance

Here's what's on the front legends

input: 105-125 vac
150watts

output: 0-8 vdc or 0-16vdc
continuous rating 6v/10a 12v/6a
intermitant rating 6v/20a 12/12a

The ampere guage has a range of 0-20 d.c. amperes
volt meter range 0-20
Has a slide switch for 6-12 volts and a pot for fine adjustment.
This old job is really a dinosuar but still works just fine.
I'm in my 50's and remember these units from my dad's shop from way
back when.
I got this one from a friend who's husband started a repair shop back
in the 40's.
I picked up his complete shop including some later model scopes and
test gens, some from as a late as the 70's. All in working order.
Haven't done any serious tweak work since my service days but thought
I'd set up a shop to do minor repair work on my own stuff.
Also wanting to get back into building some custom sound systems
before I get to old to enjoy them.
I've got tons of old Altec lansing stuff as well as some pro JBL
speakers in storage.
Been dusting it all off and am amazed to find it all still in good
working order.
Thought I'd give the youngsters around a sample of that smooth sound
we used to enjoy from tube amps and all those wonderful speakers that
were made.
unpacking my old klipshorns today and dusting them off.
Thanks again for responding, hope you can help me on this.

A 2.5 amp time delay (slow blow) should work for rated load, and carry
the intermittent load briefly, assuming it gets through the cap bank
charge up without clearing. At worst, I think a 3 amp slow blow is
low enough to prevent fire if the transformer or diodes fail.

Many thanks I'll give then a try.
