Hi guys, I was recently gifted a K300-5 that a friend of mine was going to throw away. Seeing that as a sin, I rescued it, and set out to finding out what it needed to get back to running condition. I checked the DC output on the speaker jack, and it's about 70vdc.. definitely needed help. I took off the cover and saw the power board ( PC 5021 ) was pretty neat up and burned up some components. Would anyone out there have an up close pic of this board, so I can see what was what before the blow up. Just hoping bc it will make my life a lot easier. Thanks all. Bill

70 volts sounds strange since the output stage runs on a plus and minus 39 volts.
Pm me your email address and I can take some shots of my 300s guts and send them to you.
Whatever you do don't hook it up to a speaker unless you want to blow it!
