Brand new, MINT NOS RFT* ECC82 12AU7 Halo Getter with Extra Support Rod Tubes. Made in E. Germany. One tube has Siemens Label and other is OEM no label. Identical tubes except for the label. RFT ECC82 tubes come in several construction styles. Recommended by many Tube Amp makers. In white boxes from bulk.
* comments about sonic quality are from a specific user's personal experience in a specific system. There is no such thing as the BEST tube. All fine tubes can shine in different systems. That being said, RFT like Tungsram are under appreciated tubes.
