We have about 50 RCA 12AU7 cler tops. Most are labeled "Conn" and are organ pulls. For $18 per pair, we're selling tubes matched the way you need, either section 1 to section 2 or sectionwise across tubes. Just let us know how you need them matched. If you don't know just let us know what they're going in and we can probably figure it out. What is a matched tube? We call tubes matched when they test (1) good, like new or nearly like new (90% or better) and (2) their transconductance matches within 2%. No shipping with USPS delivery area. PayPal or credit cards adds 3% ($18.54 per pair total).
