I had one bad tube socket, this the third time I have been in there and this time I just replaced all the tube sockets. She was also having other
intermittent problems so while I am in there I figured go for it. I have most of the caps laying around from working on other amps. Now, my classic
50, changing tubes out. The tubes in the 30 are brand new, I figured since I'm not using it at the moment I'll switch the tubes out. I go to take the tubes
out of the 50, take the back cover off, can't get them out that way. It's kinda dark, I can't see well, I figure hell, I'll look on you tube, nothing on you tube. It
seems you have to take the bottom cabinet panel off and then there are two plates? under the tubes screwed to the chassis that have to be removed to get
to the tubes? What were the engineers thinking that day. The classic 30 has three boards that fold into and L shape that is a pain in the butt to work with. It
looks like the 50 is one board? I haven't got back to it yet.
