Description

Up for sale, a Sylvania 5814 gold brand / gold pin tube. This is a 3 mica version with internal support rods - which tests really nicely. See pics for actual results from the tester. I have another one of these in a 2 mica version to be listed shortly in case either are a good fit for your 12AU7 slot. No box, assumed used but tests great. US bidders/buyers only please. This will ship tracked and insured. My test rig is shown below for reference. I feed the tester with 116.4V sine power (my wall voltage is all over the map, frequently approaching 130V in the summer months). This allows for absolute consistency with testing and/or matching. All tests are run in Fixed Bias mode which produces the most conservative numbers.
