6CA4 pair - I used these in my Eico HF-81 that I no longer have. Made in USA. 66/67, 69/68 (minimum Good-22 for a rectifier-EICO 635 TUBE TESTER). Fairly matched. No shorts/leakage... $35
ECF 82 pair - I have one pair of NOS Telefunken and come in their original factory boxes. These are the best you can buy (European version of the 6U8), I use a pair in my Scott 222C. $75
6U8A pair - I have one pair of RCA, very nice USA made tube. $35
2A3 pair - This is a very sweet and pretty rare pair of vintage Sylvania and are perfectly matched. They measure almost at NOS and are the best 2A3 tubes I’ve heard/used. They have the 4 springs used for vibration and resonance control of the plates. $175
