Forgive me if this has already been discovered, but while I was reading through the page on which dale resistors were used, I noticed it said there was some debate over the rh25 being the proper resistor.
That combined with dumb luck(searching on ebay for the resistors), I found this auction which looks, to me anyway, to be the resistor seen here: http://www.gbprops.com/image.php?url=/reference/10/1/16.jpg save for it’s gold finish(which could easily be remedied with some black paint/plasti-dip). The auction even says “Similar Dale RH-25”).
Anyway, according to the auction, the resistor is a PACIFIC 25CH. It’s a bit to much for my tastes, but I thought this may be of some interest to someone somewhere!
Again, sorry if this has been discovered already!
