Hard to say without seeing it in person, but on the pic of the old switch it appears the tabs are pointing to the left and on the new switch the tabs are pointing right. Do you have the switch upside down or are the terminals numbered the same as the old switch?
I believe you have the switch...
I love Orange but their prices are not based on reality for the average player. I did own 2 Tiny Terrors and sold them both. Someday I'll find that used Thunderverb 50 at a steal price.
But isn't that the idea behind Groove Tubes and others? Buy some tubes rated 5 and bias your amp then as long as you use 5's from Groove Tubes you never have to bias again. Or so the premise is. Perhaps they buy Groove Tube 5.
Just tried a pair of JJ EL34's in my H&K and they only stayed in for one band rehearsal and back in the Valve Art EL34B's went. JJ's made my amp sound thin. I learned my lesson. Gonna stick with the Shuguang EL34B's.
