Scrapping Wurlitzer Organ

[D-dog]

Hey all, been reading about scraping organs on here and came across one last week. It's a Wurlitzer made in 1974. Figured it would be a good chance to see what it entails and ROI from a newbies point of view. Then decided to take pictures of the boards and seek help identifying the valuable bits and pieces.

First thing I noticed was the amount of time to tear it apart and the number of screws involved. Literally almost filled a 20oz fruit can. Even with a bit of practice it's going to be a time consuming job.

Hope I didn't post too many pictures.
I've got a bunch more. But figured these show most of what's inside. The contacts from the keyboards are like I've read on other organ threads. But don't have the gold plating on the ends. One small cluster of switches had gold plated contact wires. The rest almost look chrome plated. And there was a long ground rod for the main key board. It is very soft and shiny.

Thanks much in advance for any help with this project.

Could you please post in a format that is recognised by the forum software, preferably png or Jpg?
Then people can see it directly.

I'd love to see your photos. We have over 300 different organ breakdowns in GEO's Facebook group. We're getting good at identifying the vintage components.

Sorry about that. Phone did an update the other day and changed the format among other annoying changes. Here's some new pictures.

The sixth pic shows a layer of metal in the middle of a ceramic cap.
The bright yellow caps have thin foil and paper rolls inside.

The ceramic disk capasitor can have silver used as the electrodes.

The axial mount resistors can have gold plated end caps.

The TO-92 package style transistors can have two solid gold bond wires.

Thanks much Janie. Had no clue about the resistor caps.

I checked for bond wires in a transistor. It was marked with a heart shape and "891" on it's side.
No wires but found a heavy gold(?) Foil. Approx 1x2mm and thick enough to hold its shape. Made a sound when dropped on a paper plate.

Very nice, the two bond wires stay encased in the black epoxy. Common to see the substrate plated, also gold or silver alloy micro chip die braze.

Did you do a base metal acid leach on the piece you're calling a foil?
