What's vague? He asked for a HF amp repair person in Maryland. That's pretty self explanatory to me.
True, he didn't give any details, but that's another matter.
I've been a ham since 61, too, and I still don't like messing with 2,000+ volts, although I do it when necessary.
Telling someone to fix it themselves because that's what hams do, is not only simplistic, but rather smug. And it's dangerous if the ham doesn't know what they are doing.
At least he didn't ask how to solder a PL-259.
