Butta,
Many thanks for the advice. Did you change all TL072s on the input pcb's?
Initially, as I get time, I'll probably try this on just a few channels and evaluate the results, although, I doubt that I'd need to mod too many channels for my purposes.
I record to either a Fostex "D" series 16 trk h/disk recorder or to my Tascam ATR-60 1" 16 trk and mix back through the console so I have channels 1 -> 16 XLRs, Ins, Outs and Inserts permanently connected. Because the Fostex is -10 and the Tascam +4, I followed the factory suggested mod BUT rather than removing the necessary resistors I added a switch to each channel allowing me to quickly adapt for either recorder.
Re the LH Master.........I had started to consider the possibility of it being a "dodgy" connection somewhere as I have twice changed any suspect IC's and the problem has ultimately returned, my thinking now being that maybe, as I pulled the pcb, I was disturbing said connection. Oddly enough, I did replace the Master fader so that is definitely worth me checking out.
Although recording has taken a back seat around here it would be nice to resolve the problems currently in the system. Most of the last 18 months has been spent learning and refining drum making processes, as far as I know, I'm only the third person here in Aust., to be making ply shells.........funny thing is with over 40 years guitaring behind me, I can't play drums to save myself :grin:
Anyways, again many thanks and there's sure to be more questions.
