2021年10月1日 · EBL21 is really an audiophile tube and deserves to be used in an tube amplifier (my opinion), that's why I asked for the help of tube specialists for a functional push-pull schematic (which really works, I am not interested in experiments considering that these tubes are rare). From the 8K, 10k which one would be most appropriate?

The Philips 21- "Key Base" tubes were initially in 1940 designed with the 9-pin base B9G like the EF50. The later series production from 1942 on however was changed to the 8-pin Locktal-base B8G designed by Sylvania. Instead of the later EBL21, the EABL21 was planned, containing 3 diodes especially for the then modern 3 diode- detector- circuit.

2021年10月1日 · See especially pages 10 and further for the use of either EBL21 and ECH21 in PP applications. Also interesting pages 178 and further regarding the ECH4, the ECH21's predecessor with the same data. As I said above, where are the objections against using a variable µ tube in AF services if even Philips advised so? Best regards!
