Hi All: Just a quick note to report my great satisfaction with a source for Vacuum Tubes for vintage radios and accessories. They have NOS 12K5 tubes - used for our Imperials' Mirror-Matic, Automatic Beam changers, radios, etc... RADIO DAZE - Vintage Radio & Electronics 7 Assembly Drive Mendon, New York Ph: (585) 624-9755 Toll-Free FAX: (800) 456-6494 www.radiodaze.com email: info@xxxxxxxxxxxxx While the website is not yet set up for electronic- transactions, it is very easy to use. I ordered the item via phone on Wednesday and it arrived via $3.85 Priority Mail on Friday. They have a $10 minimum purchase policy, so I got four of the $2.50 NOS tubes - 2 Sylvanias, 1 GE and one Raytheon, complete with original boxes. If you specify, they will supply a particular brand (pending availability). They carry a variety of other items that would probably be helpful for Imperial electrical needs. They also have NOVUS Plastic Restoration products (Cleaner, Scratch & Haze Remover...). I'm not familiar with the line, but given that the business seems to service another very 'particular' hobbyist clientele, it might be worth a try for between $2.20 and 6.20 per bottle... Anyhow, hope this is of help to someone... Jim Byers '60 Le Baron Southampton
