[OKDXA] TN8K Fun...

I just had a nice shot of adrenaline here. I have TN only on 20 m but 
they had a nice signal on 17. So, I fired up the amp (my AL-1200) and 
joined the fray. Nuthin' more fun than bustin' a big pileup.

About 15 min in I see a FLASH! accompanied by a loud POW! and the amp 
goes dark. I didn't smell anything. No smoke. Meters look OK (nothing 
permanently pinned). I check the fuses and both are blown. I get two 
spares and replace the blown ones, grit my teeth and turn it on.

Everything is fine, as if nothing unusual had happened. It was clearly a 
HV breakdown someplace. I thought maybe the plate choke had suffered an 
unfortunate resonance but, nope, it's fine. A tube glitch would have 
opened the plate choke (at least). It all seems to work perfectly fine...

73 & CU in the Pileups (maybe),
