QR Code Link to This Post
Pair of vintage RCA 6L6GC vacuum tubes with blackplate construction and etched octagon base codes. Both are USA-made and were tested on a calibrated B&K Model 204 tube tester. One tube scored **100+**, the other around **82**, both solidly in the GOOD range.
One tube has a **chipped plastic alignment post** on the center base (see photo), but it fits into sockets normally and performed at full output during testing. The other has no base damage. These are solid working tubes from a clean estate set.
While not a tight match, this pair is great for most vintage guitar amps or projects where perfect matching isn't critical.
Please call/ text the phone number I provided, as Craigslist emails often end up in spam. Cheers!
