Thought I would share this, if nothing else it might remind some of you how lucky you are that you live in the same country as the manufacturer. A few months ago I did a trade in/ upgrade, I now own new SWR SM900 and Mesa 900+ heads. The SM900 has developed that great curse - an "intermittent" fault where it occasionally make a a dreadful gushing noise that keeps on increasing in volume until you tap around on the top of the amp, which seems to stop it and all is fine. One of these things that you cannnot return for until it actually does it regularly for the serviceman. The 900+ (which I love for its tone) suddenly cut out at a gig - lights on, fuse fine, but absolutely no sound at all - no hiss, nothing. Sent it away for repair and when it returned it worked but there was a VERY loud "crack"when swiching to standby if the graphic was on (this blew a tweeter!). Naturally it is back again for service. Both amps under warranty and good dealers who will follow through but... whatever happened to factory quality control and .... hey guys, just occasionally remember how lucky you are that you have the manufacturers close by and a replacement head is days away, if necessary, not weeks or months.Sorry - just my New Year gripe, I had wanted to gig with the 900+ on New Year's Eve, instead I had the (very nice with a Sansamp) SWR and spent the whole night worrying that it might play up on me.
