Hey everyone
I recently acquired a 78 IC deluxe big muff - the first version with the blend switch
Schematic is here https://postimg.cc/F7LVjGz1
It came with a 110v transformer and plug, and Im in the 240v UK
So I took an EHX transformer from another 70s pedal I have (Clone Theory) and wired it up.
Pedal works as it should, to the best of my knowledge
Two issues however.
1 - ideally I want to get rid of the noisy transformer
2 - its getting quite hot in operation and Im not sure thats normal / risky. Not too hot to touch but very warm
3 - the pedal uses a wierd power supply set up with a rectifier diode, and Ne5554n regulator chip
The power requiremens are basically bipolar +5v and -5v
I am wondering however if its possible to run it just off +9v and ground?
Alternatively, does anyone have a nifty circuit to make +5v and -5v like a RoadRage but different??
Thanks for the help!
Ian
