This is a good score, for sure. I also bought a pristine Sony TC-440 R2R from him. It came in the original box with all the packing. It has the original Vinyl cover (unopened), hard cover still in original box (unopened) and original manual. paid $40 for that too.
I emailed the guy and asked him if he could tell me more about the kit. He said that he brought the R2R and TT back from Vietnam (early 70s), used them both for a few years, then packed them away. He didn't remember if the kit came with it. He stated that after he returned, he worked for an audio store as a salesman and it was possible he picked it up there.
Funny, he also gave me a 30+ yo new belt for the TT, but it was disintegrated in the bag. I can only image the belts in the R2R are not any better. I hope the rollers are still good or off they go to Terry.
Not much experience with TT's so it would be hard for me to identify what weights are mounted, I will just spread out the parts and take some good pics of the TT for your analysis.
I already ordered all new belts for both. I will clean and lube them properly before I do any real testing.
Since neither of them have run in decades, I will bring them up slowly with a viriac to reform the caps and check for shorts? Cosmetically, both pieces look fantastic, just need a thorough cleaning. Can't wait to hear them. Glad I could create some excitement with the adapters

These will be for sale by the way and I will be only be asking half of what they are valued at...so $500,000. I don't want to be greedy.
