Type 27 tubes made in USA. All tubes tested good on one or more of my testers: Hickok, Knight, Sencore, or Jackson. All are in a box that usually doesn’t match the tube brand.
I am listing tubes with the exact characters on the tube/base the same way it is put on the tube as best legible.
1. SOLD:RCA –UY-227-
2. SOLD:RCA UY227 (with no “dashes”)
3. SOLD:RCA Cunningham 27 (underside of base says “C12”)
4. SOLD:Majestic –G-27- (underside of base says “5”)
5. SOLD:Majestic –G-27- (“1” stamped into underside of base)
6. Sold to Phlog:Silvertone 227 (side of base says “CHD [?])
7. WARDS Superairline 27
8. sold to Phlog:Eveready Raytheon ER-227
9. Slod to PhlogPhilco 27 “1H” under the 27
10. Sold to PholgPhilco 27 “1H” under the 27
11. sold to PhlogPhilco 27 “1C” under the 27
12. Sylvania 27 (sticker with date sold: 1/20/1938)
13. National Union 27 with gray areas on base for date sold/tested
For me, moving these is a higher consideration than getting the best price. I'm still learning values on used tubes and apparently priced these too high yesterday. Are they worth $5 each? Shipping rate via USPS.
