How do I increase the voltage (with the heavy duty power supply)?
WARNING: generally, it’s not recommended to do this. You might decrease the life of your GS. Adjusting the pot expose you to HIGH-VOLTAGES which can be FATAL!!! If you feel at all in-competent, it is recommended you stick to 5v, or let a qualified electrician do it ($$$). Another reason is, performance increase from ~12 MHz to 13.75 or 15 MHz isn’t as impressive as from 7 to 9/10 MHz, probably because the GS’s 1 MHz bus limit. So it might not worth the risk/time/effort to try beyond 5v. You’re also at a much higher risk of damanging your TWGS/Zip/GS. Note: I’ve drove my GS to as high as 6 volts. Nothing blow up, except the computer just sorta reset it self. I don’t recommend you to try this. 🙂 It’s just a side note. The easiest way would be to purchase AE’s heavy duty power supply. Memory Plus Distributor (MPD sells the exact same supply (except without the AE sticker & price) for slightly cheaper. LRO also carries the MPD power supply.
