I want to remove the rectifier and regulator from my DEM...help?

Hey again,

Looking to remove the regulator from my vintage deluxe electric mistress. its the one with the internal transformer. I want to use my own power supply so i do not have to run AC to the board. Just wondering what componenets I would need to remove (if any) and where i can "plug" 12vdc+ into the board. heres a schematic: Mine has a 78L12 541Pregulator, just a small one, looks like a normal transistor maybe its a to-92 package

I cant find a schematic anywhere that has that particular regulator setup...but, theoretically...couldn't I remove the regulator and simply plug in at its output? It might go through further filtering but...so what..?


Also, does anyone know how much current these things pull? I guess it cant be that much the regulator is rated at 100ma.

I guess thats whats in mine...

That should work.  Not sure of the actual current draw but I imagine its less than 30mA. Drop a 1 ohm resistor in line with the +12 and measure it.

wow, i got THE EH man to respond  Im much more confident now 


thanks!

But hey...does anything with the grounding change?? It looks like the center tap was linked the ground...so, probably not...but just checking
