[QUOTE="OnOff, post: 507528, member: 16173"] I removed the PCB transformer from the unit I bought from America which is designed for 120VAC supply. The one that burnt out was for 220VAC. A 110VAC transformer I have here puts out 117V...near enough I figure. [ATTACH]11209._xfImport[/ATTACH] Measuring the secondary of the trannie with my meter and it's saying 17.6VAC. But that's the "open circuit" voltage coming off the secondary. When I measured the 230/15V trannie I was seeing 22VAC on the open circuit secondary. Aiming to fit a 230VAC trannie in place of the 120VAC one. Not sure whether to go with the 230/15 I have or grab a 230/12? Thinking with the 12V one the open circuit voltage might be closer to 17.6 rather than 22. Wondering tbh if the LM317T will in fact be that fussy. [/QUOTE]
