We see a lot of raised eyebrows when someone sells a nice but empty box for an easily sellable chunk of gear.
We see a lot of folks looking for paperwork that comes with gear.
We see a number of folks looking for the specific headshell or whatever for their gear. Like the azimuth adjustable Sansui h/s for their better models and the prices are steep. The Thorens headshell is not in this group because it is required, not easily replaced with a higher performance after market unit for less money as could be done with the Sansui
But if someone wants a certain piece and has lusted for it for years there is something to be said to offering the full meal deal instead of just the metal box with knobs switches buttons and dials. When it comes with the box and the extras, there is a group of buyers out there that want that and will pay for it. Making it a no questions, plug and play unit has a significant value and that is display all the time in completed sales on the bay. Nice dustcovers bring more than that scratched pos that has dust collecting on the entire system, tt included. Fuzzy pics are not the way to get the offers.
I picked up a Pioneer SA-9500 a number of years ago. It was in nicer shape than my gear and I have every box and piece of paperwork and all accessories in most cases for all my gear. This thing was sweet. But Pioneer had side inputs and outputs that faced up on this amp. Absolute dust collectors. They provided black covers for each and every RCA jack, two-prong plugs for the three AC outlets, the OM, Schematic, inner box and outer box when it was sold new. I had all of that in addition to the multipage sales brochure. I got all the money for this unit in the sales scenario I used. The seller will be able to refurb this unit, full recap, and be able to provide it to be the prized center piece of a very nice system for way more that the purchase price.
There is the AK purchase price of all this old and cheap gear and then there is the collector market. Just like vintage muscle cars. Some come with everything and sell for hundreds of thousands, but the ones we find on the side of the road and buy for peanuts, great but they need a lot of work and will never be as new but will be very nice units when we are done pouring the love all over them. And when it comes to the bay, you only need 2 people that believe they have to have that particular unit.
One thing that gets the AK crowd is they want to get the ones that need work as many enjoy doing some of the work. Folks that have never even seen a soldering iron are jumping on recaps. Howard's needs to advertise (support AK) here. Many are not willing or able to pay full boat for a collector quality unit. Nothing wrong with that. It is the reason I won't be posting some of my gear here as there isn't quite the market. We are looking for vintage and cheap and when those that have found them post values in this forum it reinforces the less expensive opportunities not the purchase of collector quality units.
