RCA RADIOTRON -UY-227 amplifier vacuum tube valve Type 27 Engraved Base. Hickok tested 900 micromhos (Spec is 1000). 90%.

Still selling off tubes acquired over 30 years of dabbling in the vintage radio hobby. This is a nice pair of two engraved base RCA Radiotron UY-227 globe style tubes. Engraved base. One has more mirrored glass than the other. I tested these tubes on my Hickok 800 mutual conductance tester. Tube readings are: Silver Tube2100 Clear Tube1550 Minimum reading is 1000 Gm so these tubes are good. PLEASE NOTE: I will not refund money on tubes that people tell me test lower on their tester. I know my testers are good and I stand by their readings. If they get broken, I will refund. If you are unhappy with it, you can send it back to me at your expense and I will refund money. Ive sold a ton of tubes over the last few months and only a couple have had issues. People are pleased as per my feedback. Ill ship anywhere in the world. Local pickup is free. If you win more than one tube auction I can combine shipping (please hold off paying if you want me to combine until I can invoice you and give you the correct shipping. Ebay notoriously over charges). If you wish to hold off shipping to bid on next weeks auctions thats fine too. Im flexible. Any questions? Just drop me line.
