Your amp should be service every year with a full cleaning of the pots, tube sockets and check of the filter caps, tubes, jacks etc. I do a spring cleaning on every amp I have and get in. In a lot of cases of Boogie's with the SUS-4 mounting they let dust get in from the gap between the chassis and cabinet. It some cases after years of electrical attraction and the fan forcing dust in there the inner chassis can look like a vaccum bag exploded. In these cases I uses a micro fiber cloth and then clean all the dirty circuit traces with PCB cleaner or denatured alcohol and a Q-Tip. I use Caig De-Oxit on the pots followed with Ca-Lube and I use De-Oxit on all tube sockets followed by Caig Pro-Gold. I generally use a curved dental pick to gently scrub carbon and heavy oxidation. A good old fashioned pipe cleaner works great as well. I then use a straight dental pick to tighten the sockets. Finally I soak the grounds with De-Oxit and if they do not look clean enough I remove the star ground washer and scrub it with Scotch-Brite until it shines. Use Scotch-Brite pads to gently clean corroded buss wire and all 1/4 in jack contacts after a good dose of contact cleaner. So spending an hour with your baby once a year will lead to a seriously reliable and trouble free tone monster.
DO NOT TOUCH THE EQ FADERS !!! ONCE CLEANED THEY WILL NEVER LUBRICATE CORRECTLY AGAIN.
Wow, I'd love to be the one to buy an amp off of you!
And thanks for that warning. Are the new mark IV sliders different from the Mark III sliders? Because I went into GC the other day and the sliders on a Mark IV combo slid very easily compared to my Mark III. I will be cleaning my amp as soon as I find a place to get this deoxit stuff.
