This is for a lot of 4 Philco Sylvania 6BK5 USA made vacuum tubes in excellent clean condition in their original boxes. They are identical made by Sylvania and have black plates and a large top round getter. See the pics for condition and all that is included. 4 tubes in total in this lot. Guaranteed good. I believe these most likely are NOS.

Check out my other items, Vintage Tubes, guitar parts and More!! I will combine items at a lower cost for shipping on multiple auctions won. second tube won usually ships free. Shipping is done by USPS. Ebay automatically adds state sales tax. For multiple items click REQUEST TOTAL FROM SELLER after Buy it Now to receive an invoice.
