Members tutu-1 Posted April 15, 2007 Members Share Posted April 15, 2007 can i recap my Silvertone twin twelve 1484? i've got a schematic and can use a soldering iron. that's about it. am i stupid to even consider it? a couple weeks ago, i posted a similar question when i was considering swapping out my output transformer. one guy said, 'go for it' so i did. i did it successfully (actually a very easy job -- easier than modding an overdrive pedal, but more risk of death i suppose), but it turns out it wasn't what was causing the abysmally quiet and distorted signal. I am guessing the next place to look in this 40 yr old amp is the capacitors, eh? maybe it should have been the first place i looked, but i've heard so much about these OT's blowing and it looked like an easy enough job that i just swapped it out (used a Hot Rod Deluxe OT) "Why don't you just take it to a tech?" Because, silly, techs are for sissies. Or, because it's a $200 amp and i'm not going to pay a tech $40/hr to have all the tinker-fun. Link to comment Share on other sites More sharing options...
Members Slaymoar Posted April 15, 2007 Members Share Posted April 15, 2007 Bring it to a tech. Caps can be pretty deadly when touched the wrong way. You can try, but keep in mind that they need to be drained using a resistor (10-100Kohm) in parallel with them, hold for about 5 seconds. Do it to all capacitors you will work on, especially if you are not sure which ones are filter caps and/or signal/coulping/drain caps. Link to comment Share on other sites More sharing options...
Members mgcasella Posted April 16, 2007 Members Share Posted April 16, 2007 Could you explain draining the capacitors more? Or provide a picture? I want to work on my amp but I don't want to kill myself :-) Link to comment Share on other sites More sharing options...
Members johngris Posted April 16, 2007 Members Share Posted April 16, 2007 Looks like some pretty good information here: http://studentweb.eku.edu/justin_holton/caps_p.html Be safe Link to comment Share on other sites More sharing options...
Members daddysguitar Posted April 16, 2007 Members Share Posted April 16, 2007 can i recap my Silvertone twin twelve 1484? . Sure; replacing the filter caps should always be done on an old amp.20 years is a pretty good age for an electrolytic cap, and replacing them is usually the first thing I do on an old amp.I usually just use short jumpers to short 'em out before I yank 'em.
