I am selling a quad of nearly matched USA made RCA 6SL7 vacuum tubes. The tubes were TV-7A/U tested and computer curve traced. The minimum for a 6SL7 on a TV-7A/U is 32; these tubes all test a nearly identical 56. That is each triode section in each tube tests 56 +/- 1.
One step beyond TV-7A/U testing is curve tracing and matching at operating voltages. I am providing test curves drawn by a curve-tracing computerized tube tester. Much more accurate than any old-fashioned tube tester. Please see the curves in the photo section for curve matching.
These tubes came from a recently passed away amateur radio operator who was a radio/TV serviceman for his day job. The original tube boxes were deteriorated from age and garage storage. Therefore I am not advertising as New In Box (NIB) or New Old Stock (NOS).
Shipping is via USPS to domestic address. USA shipping is included in the price.
