Since I had to re-arrange things a bit up there for a few more receivers, I dug my way back to the shelf with the big receivers on it.
Here's two of the Onkyo TX-8500, both are the earlier versions.
I plugged them in so they'd light up. I may have to pull the bottom one out and do some more checking because I could hear it come out of protection a few seconds after I turned it on. I may have also missed one of these in the mix, my helper swears she counted five Onkyo receivers, three of a kind, so I have to dig around a bit and see if there's two TX-4500's that I missed or if there's another TX-8500 here. (The idea of leaving isles between the shelves upstairs in the garage went out the window with the second batch of stuff she brought over).

Onkyo TX-8500
The SA-1000's were in the same area so I snapped a pic of those too, and decided to move them to another shelf, those plus the two Onkyo's were on the same shelf, I made sure they were spread out on several shelves, but all on the same level down the row.
I put the bigger receivers and amps all at elbow height due to the weight, they're harder to manage on and off the shelf and couln't imagine having to get one down from overhead or from a bottom shelf. Of course their elbow height to me.

Technics SA-1000
These both seem to work, but I didn't go beyond making sure all channels played. The controls will need cleaning and they both need a good clean and polish both in and out. They both sounded a kind of 'boomy' to me but I was only testing them on a pair of cheap Technics rack system speakers. They were light and easy to move around and I didn't much care if they got fried. They played, so they got stuck on the shelf upstairs for now.
I've owned one of these in the past and although it had more wpc than my then SX1980, I preferred the sound of the Pioneer, but I sold both of those around the same time in favor of a Harman Kardon Citation amp/preamp.
They were fun while I had them but they proved not to be the end all solution to anything. Not having had a good TX-8500, I leave that out, but out of the big receivers I've had, the STA-2100/D models sounded the best, but they don't beat out the lower power HK amps I've had here for sound or depth. I've heard Onkyo TX 8500 second version receivers, a buddy has one he bought new, and it sound good but its not the same just walking into someone else's place and taking a quick listen versus sitting down in your own listening space and seeing how it does in your own space on your speakers and your own music and source.
Any descision on any of the receivers is a long way off though.
I'm thinking that one of these, may do some time connected to a pair of my JBL 4412's down stairs come spring when I can open the doors and wake up the neighborhood a bit. Hope the like Hank Sr and ET.
The well organized inventory of all of this stuff is slowly going out the window in the name of making it fit without it taking over my house too. The upstairs in the garage is good storage but I have to watch weight, it was designed to be a guest room and not really to be a warehouse for heavy stereo gear. I just didn't want the better stuff at ground level and that area up there is well insulated and easier to keep under lock and key. I never open the garage doors unless to get a car in or out, and come winter, I don't work out here at all. There's a heater but with the cost of oil, I'll pass, the house is heated and I'll grab a few at a time and deal with them in a nice warm house. The upstairs though stays warm in the winter, especially when the leaves are off the trees a bit and let the sun hit the roof.
I've been up there when the roof was snow covered of the outside stairs so slipper with ice you could barely get up to the door and it was warm enough to not need a jacket up there. In the summer it stays cooler because the trees shade the roof well, and I do have a mini split ac unit up there.
Early this morning I got rid of all but one or two of the lesser turntables, the low end Fisher, Garrard, and BSR tables from the early 70's and the rack system junk from the 80's and 90's. It buys me two shelves of space and gained me some parts assortments from Mouser to work with. The guy has a thing for combo units, the AM/FM/8-Track/Turntable receivers from the 1970's. I also gave him most of the 8 track players, all except two Pioneer player/recorders, but those too may go his way as well. It relieved the garage of all the bottom end junk that was just clutter to me. Ceramic cartridge TT's and 8 tracks don't interest me at all and it got a stuffed van load out of the garage.
It knocks down the count on TT's from nearly 80 to under 20 or so, I kept only the Technics/Panasonic/MCS, Dual, Pioneer, Yamaha, and two Denon TT's. I saved one CEC built Fisher and two direct drive Fisher models. It cut the TT's down to what fits on one shelf.
Next is to get the odd brand stuff gone, all the department store stuff will have to go away. Most of it looks to be low end Panasonic or Foster built, so that means some parts will be worth keeping. Feet, knobs, big transistors, transformers, etc. but the plywood cabinets are headed for the burn pile I suppose. I already have a about half of a five gallon bucket full misc knobs here that came from the same place. I'll bag and tag what I take off and just add to that bucket for now. At this point I don't have the space to waste on the cheap stuff if it doesn't work.
I'll likely be going through tape decks for the rest of the week the way it looks. I got the rest of the belts I ordered so I hopefully have all that I'll need to get these up and running again. Then I'll start weeding out those I don't want.
