Hello,
This is my first post I hope I get things right. I've been using AK for about a year and a half, this is an amazing place. Last fall I completed a restoration of a 9090db, it's up and running and sounds great. This web site has been a great help in bringing the unit back to life. A past owner apparently had some problems with the protection board and decided to outboard the relay using this huge relay in an octal socket and lamp cord to wire it in to the PCB. Relay was glued to the side of the chassis, the PCB was also broken in two places. I found a board on ebay, after changing the caps I installed it in the unit. Here's where we get to the question, finally. When power is applied it takes just shy of 9 seconds to come out of protection, this seems excessive since it takes just under 4 seconds for my 9090. I initially built up tnsilvers new driver board, and I also found an original on ebay and shotgunned nearly all the parts. No matter which driver I use the 9 sec timeout stays the same. It should be a lot quicker, right? I'm not educated enough in electronics to understand how the protection circuit works so I'm asking the experts here for some thoughts.
Thanks in advance for any help,
