I agree with rrinker about Kemner's in Pottstown, PA. It was a disappointment. I ran into him as we were checking out. I bought some Pomona BNC to banana adapters ($2/ea). I had already been there for at least two hours and I was on borrowed time at that point.
It's a large warehouse with one main area and about a dozen smaller rooms. We were greeted at the door and given a 5 minute tour of the place before rummaging around on our own. It seemed to be a father and daughter running the place. Religious music was piped into all rooms.
Stuff was mostly organized into shelves and piles, but parts and equipment were spread out everywhere. It looks like they stopped 99% of their inventory acquisition in the mid- to late-80's. If I was still experimenting with tube projects/repair, this would have been a goldmine back then. I was surprised to find a few inches of SMD tape (MMBT3906 transistors) in a parts drawer.
They had a bunch of old scopes, including some Tek 7000 mainframes and plugins, but they were all in need of some serious care and were priced about 2x to 5x what you might find on ebay for stuff in better shape. Haggling was encouraged, we were told on our tour, but there weren't any high price items I wanted so I don't know how low they would go. There were some assorted Tek probes that weren't in terrible shape for $25. I would have bought them for the sticker price if I needed some probes.
There was an RF coupler for $12, which wasn't too bad, and a Tek P6430 temperature probe for $25. The P6430 is somewhat of a rare item, and was one of the few things priced reasonably (I didn't buy it - nothing to plug it into).
Books, training manuals, and magazines were everywhere from as far back as 1889. Maybe there were some even older, but every time I started moving around the stacks my nose started running. Everything was very dusty. You also had to watch where you were walking. I was constantly kicking boxes that were placed on the floor in front of the shelves because there was no more room on the shelves.
It would be a good place to play "name that thing". I recognized almost all of it except for an item or two. I don't know if that's good or bad. There's one thing I had no idea, which is the big orange trapezoid thing you can see in one of the pictures.
My wife's favorite item for combined technology was a clock/radio/can-opener. It was missing the can-opener mechanics. No surprise.
As far as TEA goes, the visit was partially curative. I couldn't help thinking about all the stuff that I'm buying (or collecting?) now that will end up rusting away in a place like this.
Here are the photos I took:

If you're in the area, go for the experience. But if you have TEA with antiquing complications, you might be in trouble.
