G'day All,
Well you learn something new everyday. I was having problems with my '67 AC30 TB with the E & B string notes. They were getting very trebly and breaking up with a warbling type effect( thats the only word I can describe it as), so was told it could be the speakers, could be dry solder joints, could be this, could be that. Anyhow I replaced all the valves (preamp & power) and bingo! the problem was still there.
Rang my mate Phil E and asked who fixes his amps. Gave me the chaps number rang him drove 30 klms to let him have a look at it. I took over the FR Strat , plugged it in for him to have a listen to my problem and low and behold, not a bloody thing went wrong. I felt like the proverbial goose and he smiled at me and said" do you use a fan behind the amp. I said yes and said "well I beleive that is your problem". Wind from the fan apparently breaking up the notes. Brought it back home and Voila! Took away the fan & no warbling. Put the bigger fan I use in front of the amp as I stand infront of the amp and once again the warbling sound took place again . Took away the fan from the front of the amp - no warbling and the sound is back to where it should be.
Bloody idiot!!!
cheers

Dear Tom

Thanks for posting your troubles......As Pollyanna would say...."How lucky you are to have had the warbling or you wouldn't now be enjoying the wonderful 1967 AC TB with new valves....and you have some spares...." That girl gets really annoying at times!

However, I live in Lancashire, northern England where it was minus 10 recently! Last night I ventured into a room we don't heat to play my guitar so as not to disturb the family. I lasted ten minutes before the cold took me back to the lounge. I could have dragged my AC30 into the room to heat it!

So....the concept of a fan....!!!.......HHmmmmm............ tell me more about the heat!......do you have......have....sunshine?

You're not the only one .....

Last summer we were setting up in a theatre and it was baking hot - so we put a couple of industrial sized fans (the rotary blade type ones - not the knicker throwing type ) either side of the stage - just before going on I went out for a final tune up and couldn't get the guitar in tune - it really was bizarre. After about 5 mins I realised the fan was blowing directly at my guitar affecting the strings !!! turned my back to the fan (which you should never do ) and hey presto - tuning no problem.

regards
Mark.
