Hey guys, this is obviously my first time posting on yall's forums, but I am having a big problem with my Randall amp head right now and would be appreciative beyond measure if I could get a fix for it. I have a randall rh 100 amp head and one day I went to turn it on and jam as usual and when I hit the switch it was as if the sound started to slowly dim out and it blew the fuse. So my next step in trouble shooting it myself was, practically, just putting another fuse in the power switch. Well the same thing happened and I cant seem to find out what is happening exactly thanks a plenty to who ever gets back to me guys. :dbtu:
Might have a blown component? I would examine the board for any obvious place that look like they have been exposed to heat or burnt components etc... I would also check for cracked solder joints especially around the power amp section, that is very common... You can run from your effects send output direct into something and see if you get any signal... this will just be coming from your preamp section, if you get signal then you know it's not anything in the preamp section. Check all of the solder joints around Q8 thru Q16.
