Is the Manley amp fixed bias or cathode bias? If fixed you must adjust the bias current so the EL34's do not exceed their plate current limit. A multimeter is needed. Ask Manley for the procedure. You can do it yourself.
Blown tube issue
So one of my Tung Sol EL34s blew last weekend after 6 months and I’m not running them constantly. Manley is replacing for me.
My question is : is it ok to pop in a random EL34 in the interim and how does that affect sound ? Same brand better ? These tubes I bought from Manley are all bias numbered . Not sure if there is an exact slot order to the numeration .
Another thing that concerns me is I bought the snappers used from some Agon user who replaced/upgraded the caps . I’ve been told depending on his work this could be the reason I’ve already blown 2 power tubes in 1.5 years ? Anything I can be aware of appreciated !
my setup :

Manley jumbo shrimp pre
