VTypeV4 Posted June 29 Share Posted June 29 I took my 300-SMX to a show the other night and it got very unhappy with me which quickly ended in the silent treatment.. 😬 I'd been using it at home these last few days as it wasn't really practical take one of the V-Type amps and associated cabs as the sound is a little different plus the venue was somewhat 'cosy'. Paired with my Trace Elliot 2103H (2x10) cab, the compact setup packs quite a punch and was ideal for the situation. I played about three notes that sounded fine but then the sound just kind of 'fizzled' out. The lights stayed on as did the direct out so I worked round the lack of power amp and speakers - the performance was well recieved. Today, I began investigating and quickly found both the on-board fuses (both T5A) associated with the power amp section had blown. I happened to have some spares so removed the bad ones and put the new ones in place and fired it up. No smoke, no funny smells and most importantly, no popped fuses so I powered it down and recreated the failed setup with the same cables and speaker cab. Still, no blown fuses, no odd behaviour or even the hint of a problem. This unit is a later example with the much improved Clive Button Mosfet 300w board rather than the older and slightly twitchy 'Bi-Polar Bear' power stage. I played the amp (far too loudly for the house!) for about 10 mins - far longer than at the venue and it held solid so I've since buttoned it back up and it appears to be back in full health. Can anyone shed a bit of light on what might have happened? Quote Link to comment Share on other sites More sharing options...
MoonBassAlpha Posted July 13 Share Posted July 13 @VTypeV4 I'd check your speaker cables very carefully for shorts, and damage along their length. The fuses were almost certainly blown by a short. If the cables check out, have a peer inside the cab in case there's something loose. If the cab has a crossover, that's the first place I'd look for dry joints or charred components . Hope that helps. 1 Quote Link to comment Share on other sites More sharing options...
VTypeV4 Posted July 14 Author Share Posted July 14 Thanks for that ^^ @MoonBassAlpha - I'll go through the cable and pull the cab apart again but typically, nothing has misbehaved since. 😬 Quote Link to comment Share on other sites More sharing options...
