Hi everyone
well I replaced all the caps including Electrolytics . replaced 3 bad tubes. and fired her up and she plays beautiful. Only problem is the bass switch doesn't do anything. tone works perfect. Checked connections all good. Looking at it I notice there is only one connection used out of the 3 posts on the base switch. And on that one post it goes to ground through a .006 cap and goes to the switch through a condenser or resister. (brown square ceramic disk) Seems like there would have to be another wire connected to it to work as a reostat. CAn anybody shed some light on this problem?? Oh yes I couldn't check either # 41 tubes. I assume they are good. Could one of them being bad have anything to do with the base not working?


Thanks for any Help
Bob
