eBay For sale is your choice of vintage vacuum tube adapters, left behind in the electronics parts inventory of my late father. He was a radio and other electronics serviceman for much of his life, and an active and avid HAM radio operator for over 70 years. His inventory was kept in a dry, smoke-free home. I hope that these are adapters that you would love to keep in your inventory of vintage radio restoration parts!! My husband helped me out a bit (actually a lot!) with some research on what these items are. He also set up a helpful chart for you to see what these specific adapters will do. Here’s some of what he found: These vintage adapters were designed to permit substitution of common or low cost vacuum tubes for expensive, hard to find vacuum tubes. Patents on some adaptors date to 1945. They are made in USA. You can expand your product offering by combining a tube in your inventory with an appropriate Adapter; OR you can use the adapter to balance your inventory. Example: Adding a JFD Co. Adapter 47A to a 7A8 vacuum tube creates a combination that can be used to replace a 12SA7. As found in an Adaptol ad in the May, 1945 issue of Radio & Television Retailing: Repairmen. Replace a hard-to-find or expensive tube with a more available or lower cost tube by pairing it with the appropriate adapter, or use a spare vacuum tube with the proper adapter to avoid an expensive purchase. For example: Instead of paying $14.00 for a 6A8 vacuum tube, use the adapter with a 7B8 tube worth only $3.00. Here’s what these specific adapters will do: To Replace This Tube Substitute This Tube Plus This Adapter Quantity Condition 6A8 7B8 72AG by JFD 2 NOS in box 12A8 7A8 72AG by JFD with data sheet 12A8 14B8 72AG by JFD _______________________________________________________________________________ 12SA7 7A8 47A by JFD 12 NOS in box ______________________________________________________________________with data sheet 12SA7 7B7 50 by Adaptol 4 NOS, no box 14A7 50 by Adaptol ________________________________________________________________________________ (Note: Adaptol #50 is similar to JFD #61A) (Also note: This vacuum tube accessory is NOT a socket-saver, or socket extender, although it closely resembles them in appearance!) At any rate, these are fun collectable pieces of radio history that might be neat pieces to have in your collection! If you want more than one, note the quantity savings. Also, note that you pay $4.50 for the first one, and any additions are shipped with no additional shipping cost! Email me an offer on the whole lot! Thanks for looking here!! (radio shelves)
