Up for sale here is this new red plastic replacement jewel for Fisher tube amplifiers and preamplifiers. You may need to clean out the old glue in the socket. This will snap in and will not need glue or anything. The face is flat, not faceted, and it looks really good when installed. Exact dimensions of the jewel are 7.25mm long, 4.25 mm center diameter, 5mm rear diameter, 4.75mm front diameter. The inside is 3mm in diameter. I have red and green jewels available as well. Just use "add to cart" on whatever you need, then check out and the shipping will combine automatically. Please see my pictures for details.
Please note that this will not fit the KX-200, since that uses a larger jewel for some reason.
US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
