You should try - but! Right now, the main pavilion is sold out, and has been since last September. So, you would be relegated to the second pavilion with about 1/3 the vendors of the main. Not to suggest that this is a poor location - most of the very highest end audio stuff was to be found in the second pavilion, as it happens. But, you are far from the club table where information is given out and announcements are made. When this meet started some years ago, it was 1/2 of one pavilion and ran for 6 hours, billing itself as "Not Rochester". Today it is 1-2/3 pavilions and runs, effectively, for 60 hours. AKA, the BEAST from the EAST. Rochester, today, is an afterthought.
NOTE: I broadcast on 1380 AM and 92.1FM from the club table, and I have the capacity to make announcements OTA. So, if a radio is tuned conveniently nearby, you may use those services. We generally broadcast vintage big-band, radio shows and such, along with many PSAs for the auction, club services and such. I also keep a small range of tools, including hand-tools, two DVMs, one LCR, one ESR, a signal injector, generator and such-like for the basic diagnostic services the club also offers. And, a very fine tube tester (Hickok 539B).
Re: Your particular specialty: The BIN (Buy-It-Now) table usually has a reasonable selection of BBs, mostly in fairly poor shape, but could be excellent sources for parts, especially appearance parts. So, for $5 - $25, you could fill a small van with restoration parts and candidates for same.
Find me at the club table. The bald/bearded guy sitting behind all the tools.
