So I picked up an old PAT4 preamp for $55, not even sure if it works or not, but don't really care, bought it for the chassis and hopefully some other parts I might be able to use.
But I am going to convert the PAT4 into a SP9 preamp. Pretty much have to gut the PAT4, buy the SP9 main PCB kit, PH10 phono preamp kit and associated bits and pieces, do some re work on the front and rear of the chassis and design and have made a completely new front & rear facia panel, I'll be using Front Panel Express for that.
Since I do not have a tape deck, will not install that switch/option and keep the audio inputs to a minimum, Phono, CD, Tuner and one Aux.
Might have been easier and perhaps cheaper to just buy the complete SP9 kit, but then I might not have as much fun!!
Once I start the project, will post photo's etc as it progresses.
