Hello all! Let me say thanks to anyone who responds in advance! So let me start by saying that I know squat about electronics though I have started doing some reading. My only hands-on electronic experience is putting together a kit or two from radio shack when I was a kid. Now that we've got that out of the way I acquired a Scott 208 a while back and after using it a few times a tube started to redplate. Of course I immediately unplugged the amp and it has sat in my closet ever since. From the reading I've done it seems the likely culprits are a bad tube, the voltage going to the socket being off in some way, or perhaps a problem with the socket itself. This amp has been partially recapped and was checked out by a tech prior to my purchase and was proclaimed 'in good operating condition'. I've been planning on taking it to a tech but having been a member here for a little while and respecting the DIY spirit that's here in abundance I've thought maybe I could give it a try on my own. My biggest priorities are not damaging the amp, my speakers (perhaps I should get some cheapies at goodwill to hook up to it until I feel certain the problem has been addressed), or myself! The only equipment I own is a cheap multimeter (which I don't really know how to use aside from adjusting bias on the st-70 I used to own). I definitely will get a soldering iron (cheap suggestions?). I would love to gain the confidence to go through the whole amp and replace any remaing caps (after practicing my soldering skills on something else) and make sure that it is in safe and up-to-spec operating condition. But frankly I'm totally intimidated by the idea of trying to learn on this rare and beautiful amp. I'm including some pics of the 208 and my 355 as well so you all can see what beauties they are. Any help is greatly appreciated, I love this beautiful amp!
