![]() ![]() Have you even tested the board yet? For all this time have you actually even verified the problem lies within the power supply board? QuoteObviously, I'm no expert in these matters. It may not be an easy fix so if you can deduce the power supply being dead and the fault being in something else but the fuse or failed rectifier circuit then likely easiest repair might be ordering a replacement board from Fender. That will still keep the rectifier going, does not burn the fuse or blow any components, it just stops the switching from working and effectively you're left with a dead power supply. If not, THEN it could be something as simple as a fuse issue.īUT I've seen plenty of that SMPS stuff failing in the regulator control circuit. ![]() After that you should pretty easily find out whether its internal rectifier works and provides the HT for the switchers. Anyway, I'm pretty sure there should be something.Įven without locating the fuse you should be able to quite easily test if the power supply (which I believe is of switch-mode -type in those things) is giving up anything. a SMT fuse which will resemble pretty much any other SMT component, so it doesn't really jump out as being a fuse in an instant. ![]() I don't know all the tidbits of regulations in various countries but I doubt things could be passed on without a fuse these days and I don't know if the regulations would pass on a fuse integrated to transformer as the sole fusing means.Īnyway, sometimes fuses may look more or less like any other soldered-in component so you may not neccessarily find a glass fuse in a fuse holder or something similar. That one, as far as I know, will just have a regular IEC connector without the internal fuse holder. ![]()
