Trying to trouble shoot Hum with LP PSU Pre
#6
Hi Kevin.



Email sent.



We have really been struggling to get this whole thing together. The instructions that came with the kit(s) were somewhat confusing. I've attached what we have as far as those go. Over the coarse of time, did those get changed/updated?



The top photo in this thread shows the front of the amp. From left to right,  AC power lamp (under that power on/off switch), Mid, Bass, Treble, Gain, Master, and then guitar input.



On the back left to right: AC power, effects loop (yellow) wire, Speakon speaker connector.



We've heard on other forums that the star ground is the best route to go for grounding. The TUT3 book looks interesting but @ $86.00 a bit out of our range. Can you offer any other advice?



Thanks again,



Jonathan
