Make note to your self for future amp builds take those burned out old preamp tubes and insert into the tube socket before you solder the tube pins.
That way you won't have solder running into the tube sockets. I found out the hard way

Ha! I actually thought about it but the thought of accidently soldering a tube into the socket would be even more embarrassing when I had to ask for help with getting it out.
Not really. It is a great tip for a couple reasons that aren't apparent until you do a few. Tubes swap in easier if the pins are already lined up perfectly. Easier feeding means less grumbling and pin bending... or breaking.
Of course I have never grumbled or bent a pin..

...Any suggestions for cleaning this out
If we're playing bush mechanics: you can take the socket out, hold it in your hand with the solder connections pointing down and get the blocked pin good and hot with the soldering iron, then quickly whack your hand down onto the bench so that the still molten solder is shocked out of the hole. The idea is to hit your hand on the bench, rather than the socket to avoid smashing it!
I used to de-solder PCBs this way to salvage components before I had a solder-sucker / money to buy new parts.

Umph.... visions of my past coming back to haunt me.... I used to do this with pcb's too, and until now, I had thankfully forgotten all about it! Actually, I used to slap the board on the bench to evacuate component holes after removing the component..... Such finesse!
(Local TV 'repair' shop used to dump old sets down an embankment where they rolled into the river - all illegal, of course, but nobody was bothered in the late '70s. People are paying top dollar for those old carbon comp resistors & crappy caps now - maybe I should buy the land and open a mojo mine??)
Back in the day, in Detroit, the city let folks haul their dead TVs to the curb one night a year. The city trash department would take them the next morning. Except for the ones my buddies and I would stuff into cars, and later scavenge parts from.
