Have I damaged my amp?

I am playing through an Marshall EL34 50/50 in stereo via an Marshall 1936 @16ohm inside an Iso Cabinet.
The 2 speakers are miced and panned L/R inside the Iso Cab. Tonight during rehearsals I realised after about 30 minutes of playing that volume was lower on left Channel than on right. After checking for tube faults etc I discovered that left speaker cable was pulled half way out thus there was no work load on left side of the amp. The left microphone had been picking up the signal from right speaker therefore I didnt immediately discover this. After reconnecting the speaker load i checked the amp and it seems to work fine, but im very worried I damaged transistors or best case tubes...

I played about 30 minutes with volume at 12 o´clock.

Is there a chance I have damaged the amp so it eventually will blow up on me? We have a gig in 3 weeks time and I dont want to run the risk og having my amp die on me during the show.

On the other hand I cannot imagine im the only one having done this over the years...

Pleased to hear :-)

It could have damaged the output transformer if anything, but I'll let a more learned amp scholar speak up on that.

If it didn't smoke when you were doing it, it's probably fine, the only way to know is to keep using it.

BTW, I think you meant transformers, not transistors, shouldn't be any transistors in the output stages of a tube amp.

Yes, sorry meant transformers :-)

Many thanks for the replies - So far all seems to be working normally ....fingers crossed it will not die on me anytime soon.
