Well, I knew these things were kind of fragile, but......   Today I was installing some rf chokes onto some of the cables on my Alpha 87A.  I accidentally dropped one on top of the amp while it was turned on.  Not hard, just a little bit of a thump.  Well the amp shut itself off.  When I tried to power it back up, I get error 24.  I can't believe such a minor incident would cause such a major problem.  Do any of you guys have any suggestions of what I should look for?  Apparently this is a low or high voltage problem.  Thanks for your help and happy 4th.  73 Mike WB0SND

Well it looks like I've answered my own question.  This is the first time I've had a hard fault with this amp.  I didn't read the manual thoroughly the first time and didn't realize you were supposed to wait for the entire warmup cycle for the fault to reset.  So, I did just that and it did reset and all is well.  I guess the little thump must have momentarily shorted something or maybe rattled the interlock switch or something.....  I'm glad I didn't get to Fault 99 before I figured it out.
