PSU II, Phono II problem
 
I've been using a PSU II and Phono II for years and trying to fix a low 50Hz hum last night I managed to blow it up. The "magic smoke smell' seems to be coming from the PSU.

I'm keen to have a look to see if it is recoverable, but don't have a circuit diagram any more, or any info about what the test voltages should be. If anyone can share this info it would be much appreciated.

Thanks!

Nick

Hi Nick, Greg is the man you need to contact, he has all the circuit diagrams and can send to you, it is a very simple PSU and powering just the Phono is very low current about 4 to 5 mA. Lots of help on here. Bob

Thanks Bob - I’ve sent a message to him directly. Once I have some measurements and am out of my depth (won’t be long!) I’ll come back on the forum for help/solace.
