OHHH NOOO. . . 1967 Marshall 100 watt Super Tremolo

[orfeo]

I know, I know, I know I know better. . .  but like an idiot, I plugged in and turned on my 1967 plexi with no speaker cab attached.  When I got no sound, I turned it up and then realized what I did.  Turned it off right away, waited a few breathless moments, and then I hooked up the speaker cab and turned it on. . .

Nothin', no sound now.  I assume I blew the output transformer?  Mercury Magnetics will test my OT for free if I send it to them. . . Am I thinkin' down the right path?

Did you check fuses and/or try different tubes?

Is the speaker wires hooked up and you have continuity from the amp head to the cab?

I'm at work right now, but I'll try to check those items tomorrow if I can and report back.  If I remember correctly, I did check fuses.  This calamity actually happened a few years ago, and I got so upset that I just packed away the amp in my closet and haven't touched it since.  I actually feel physical pain when I think about it!

Chances are you probably just popped a fuse, pray for your tubes.  When you do open it up, try to take a look at the transformers.  I've seen a mix of Drake and Dagnall and all Dagnall in the old pre-1969 Supers.  If it has a Drake optx, it will sound a slightly different from a Dagnall.  A little more compressed when opened up.

Good luck!

If it was the correct fuse it should have saved it ....I won't tell you why I know that....but there was smoke all over and a stink you won't soon forget
