Tube discovery and question

A little back story.  When I got married, we bought my grandparents' old house.  Today I needed to stow stuff in our surprisingly packed crawl space, and I have learned that my grandfather never threw anything out in his life.

Today's interesting discovery was a really old radio and a pair of monoblocks that I assume went with it at one point.  They are in truly terrible condition, but they had a bunch of tubes in them.  This included four RCA grey-glass 6V6GT, all in excellent looking condition once I wiped off the dust.  One pair is in my MP-301 right now, and they sound pretty freakin' awesome.

So, here's the question: I assume not, but are the EF93-based 6BA6 compatible with the EF95 that I have in the same amp?  They look the same size, but I know one letter difference can sometimes mean a really big difference.

As a bonus, there are some other tubes here that look to be in decent condition.  If any of them would be of use to anyone in North America, you are welcome to them for the price of shipping.  A caveat: I have no idea whether they work or how much they have been used.  Most look like they have been used, but others actually look brand new.  If the RCAs are any indication, they might be worth it for someone.  My Grandpa was a bit of a stickler, so I'd be surprised if they aren't matched, but I have no way of testing them.

2X 5Y3GT - One is a Rogers made in Holland, the other a Canadian made GE

2X 6J5 - These are both Westinghouse, and are in metal sleeves.  These look a bit more worn than the rest.

1X 12AT7 - Westinghouse again, and looks unused.

2X 6BA6 (again, I don't know if these would work in my amp)

I also seem to have a single 6AV6--can't read the company name anymore

There's also a single stubby little GE guy, but I can't see a number on it.  I could take a picture if that would help.

I'll try to get some pictures tomorrow.  It's not too pretty, though.

No pics yet, but I pulled everything out of the crawl space and had a closer look.

The radio is completely unsalvageable.  The front panel is busted up, and there are several loose wires and components sticking out from the back.  I definitely wouldn't plug it in.

The two amplifiers look a bit more promising.  They are dirty, ugly and heavy, but they seem to be solidly wired point-to-point underneath, and all of the wiring is fully accessible.  The output is currently hooked up to an RCA plug, but that would be easy enough to change.  More odd is the input, which is a 6 pin socket, which looks quite a bit like the tube sockets, except a little bigger.  I would have no idea what to do with that, especially considering that there should only need to be two connectors for a mono signal.

I will try to get a couple pictures up of them, and might try to get the amps working once I have the time.  Not sure what kind of shape some of those components are in, though they actually look mechanically solid on the most part.

My dad remembers my grandfather updating many of the components of his stereo at some point, and this is probably it.  I wouldn't be able to guess how long it's been kicking around in the crawl space, though.

It'd be really nice if he had some NOS tubes kicking around down there as backup, but I seriously doubt it.
