FULL NOS TUBES
The WESTERN ELECTRIC 437A is the ULTIMATE SUPER TUBEfor audio.Nothing comes even close. Not all... period. Developed by the scientists at Bell Labs, these tubes were created with absolute precision and excellence in engineering. Like the WE300b, these cannot be duplicated. Others may try.... but sorry, not even close to the real deal. 6C45 is an amateur exercisecompared to these glass perfections. These are the REAL DEAL! Bottom line: you can't get pinnacle audio without pinnacle engineering - especially with vacuum tubes.

Message us if you need sockets for these.-> -> -> and they are simply breathtakingly BEAUTIFUL!TESTING:We use a Kennedy calibrated Hickok 752A with a very custom proprietary 9pin 50mil pin fixture applied to the conventional 9pin compactron 752A socket. We verify all voltages/currents with our Tek TM5000 audio test bench that ties into the fixture. WE437s are tested at -3V verified grid and 100mv AC drive (not from the Hickok). Plate currents vary with the exact transconductance, but we center our operating point at the data sheet value of 25ma via constant current anode source in series with the 752A. This takes the sloppy 752A plate supply out of the test, yet uses the handy 752 infrastructure for testing/matching. This system was developed for validating our ENLITEN AUDIO(tm) audio products. We cannot guarantee your tester will match our calibrated test system as there are way too many variables in the testing equation. Testers vary WIDELY and can have significant levels of measurement tolerances.
