there is a wonderful and low cost hallicrafters decade box for sale on ebay now,, 45$,, and is a very nice looking unit.
its one of those... "too much box" with very little inside it type containers that could be modified to a wayyyyyyy lower profile.
the person selling opened it up and it finally gives me a way to use up half my NOS slider switches i have.
i have so many resistors that i am going to make my own... and duplicate this layout.
I dont know why i didnt think of this design,, i was always associating what i used in the navy,, (rotary switch type) as my starting point.
the max wattage may be the only slipping point for the type / application uses we have on our heat generating sets.
i suppose you would have to just know when the decade box is applicable and when its not.
on this box,, i did not see a way to parallel resistors... meaning lets assume all these are 1/2W R's.
your sample radio says 2w 100ohms for a particular schematic need.
on the decade box i would want to select or "turn on" 5) 500 ohm 1/2w resistors in parallel to achieve 100ohms 2 1/2w..
