[quote name='umph' post='959435' date='Sep 17 2010, 01:47 PM']did you use the correct value of fuse? The new valves may have been pulling far to much current and taken the fuse.[/quote]
Yeah, according to the back of the amp. 3.15A
Right a little update. I've opened the bastard up. I had a wee tap on all the tubes and most of them seemed pretty wacked, but I took the two worst ones out and switched it on. Fuse blows, but it comes on. Progress.
So I figured the four new tubes my tech put in should be working fine. I pulled out the 8 old ones and left the four new ones. I switch it on and HUZZAH! It's working, BUT after about 5 mins one of the 4 tubes is glowing super hot, so I switch it off. I figure that tube is prolly pretty much dead now.
Any reason why this could happen? I noticed that the tube directly to the right of it of it was not quite in the socket, could this be why?
Also, say this is the lay out of the tubes in the amp:
t t t t t t t t
t t t t t t t t
how do the pairs work - like this?
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7 8
or like this?
7 5 3 1 1 3 5 7
8 6 4 2 2 4 6 8
Thanks again!
