:!: I am currently working on some pin 1 issues that is complex in scope due to antenna structures 600 feet away, faulty power wiring in the house, and of course the Mfr bad choice of circuitry.
:?: I have some questions about A,B, C, grounding. That is circuit board ground - A - , Power Supply Ground - B - , and Chassis Ground - C -.
:?: Anyone here familiar with these issues?
I am new here so please forgive any patronizing. 8)
Here is my 1st question:
Can I simply lift the PCB in the guitar effects rack system, Roland GP-8, from the wrong ground setup state it is in now - where A=B=C - and make it such that A=A and B=C?
Besides making sure the grounds on the board are connected to each other and not to Chassis or Power ground, I also need to isolate any grounds from being transfered from sub system boards to the main via connectors. Are there any other concerns I need to verify prior to this work being implemented that would make my life easier?
Thanks for your help
