1956 Hoffman Colorcaster (56K Warning - Lots of Photos)

If you need any additional guidance making the mod, I will be glad to assist with what ever information I can provide. Good Luck. I know this will work, because it worked very well for me. A lot will depend on the skill of your craftsmanship. But with the right tools and materials, it is easily done.

One tip, if the brass shim stock fits to loose between the bakelite body and the resistance element, make the brass strip longer and double the thickness where it makes contact with the resistance element. Or possibly use thicker shim stock. The idea is to get a nice snug/tight fit so the shim stock makes good contact.

Hey, if you try the add-a-tap trick, how about taking a couple of photos? I have a set with a tapped 10-ohm WW pot that needs help, and a pic is worth 1,000 worlds.

When I do the mod for Ben, I will document the procedure with a How To page on my website and place a link on this thread.

WARNING!!!! DO NOT use automotive heater hose for your "listener"... radiator/heater hoses are impregnated with carbon to mitigate electrolysis in the cooling system... be careful!

I just finished doing this center tap mod on a 10 ohm 4 watt Clarostat pot for Phil Nelson. I have documented the procedure and posted instructions and photos at my web site under the "My Methods" section. It's the bottom entry "Pot Center Tap Mod"

Link to my web site is at the bottom of this post.
