Post some picture showing wiring and close up picture so we can help you
since Apex is not online
ok i will post picture another day because i chatting at cyber cafe now.when i use 2 pair power output it should change resistor value for adjust bias?or u think my ground connection problem?
maybe you have problem with your wiring,, i run B500 on trapo 55vac -/+75 work fine no problem
