ok, went over this morning to check these out
they are pretty big but not unmanageable, they are all in various states of disrepair. I noted some are missing parts of the tape transport, record or playback heads etc.
Many of the plugin cards are loose or maybe just randomly inserted, missing etc. The top section is just the tape transport, behind the reels are a fair bit of power control things. I couldn't really tell as i could not open the doors fully.
The base is the controls, control logic and the record/playback I/O cards. Power supplies are probably in the lowest section.
I recon someone has been using these as spares to keep one of them running.
There are some more to be listed, i counted six in total including the ones already on ebay.
i didn't buy any while i was there, but i did come back with a souvenir reel from one of those due to be listed.
I forgot to ask about on-site teardown, but they are usually pretty short on space and with all the activity with people, fork lifts etc they have there i don't think i would have had a favourable response anyway.
