Hi Folks,

My 5A fuse blew this morning when I was firing up the amp from standby to on. I replaced the fuse and only turned the amp on and left the standby off. I noticed that one of the middle Winged C tubes had no lights on it so it is done, no question.

I have a spare pair of Ruby EL34BSTR tubes.
Can I put those in as a pair to get me through a couple of gigs this weekend or am I asking for trouble?
Do these need to be changed in pairs like some of my previous amps?
I think it is the V8 that is bad. Looking behind the head, it is the third one out from the left of the choke.

I put one the BSTRs in that slot and it lit up as it should so I think everything is fine but I just wanted to check with you gents here who have some much greater knowledge of this amp that I do as I have only had it since Nov of last year. Absolutely love it though!
 
One at a time works fine.
Unless it's like 10mA off from the other tubes it won't hurt a thing mix'n one
good one with the rest
Just check the bias
 
Thx Gents! Running 2 tubes in low power mode. All good!
