Joris STK465 datasheet. Common Russian Tubes Russian General purpose tubes. IIRC correctly, Kurt even used a tube amp for heating the filaments of his test bed amp! 6p21s tube datasheet. The caveat for audio use is that with high Rg1 so it should be used either with 6p21s cathode bias, fixed bias, the tube is prone to screen overload, with low Rg1 if fixed 6p21s bias is used. Anybody has experience along those lines? electron Tube Data sheets datasheet Tube type list The following list shows the tube types I have entered in my database, with exception of the service types ( e. An article discloses the output spectra of amplifier when using various tubes.
It is dedicated to be used in audio frequency range which datasheet requires the output power 100W. 6P21S 6 021 0, 4 0, 389 0, % 5, 137 0 50. : - ) I' m a bit concerned by the low cold filament resistance some tubes datasheet exhibit, but a pre- heat circuit is possible. 6p21s Direct heating cathode, 6p21s datasheet medium power consumption triode is used for class A amplification. datasheet Shuguang Vacuum Tube 300B Series Triode: 300BB) DESCRIPTION 300B- 98 is compatible with 300B 6p21s Vacuum tube 300B- 98 is new and improved 6p21s version of 300B. Name: 6P21S; Type: beam tetrode;. A 6P21S happens to have 8 ohms resistance. Any Sub- miniature types are just the same as US / Europe B5A B8D sub- miniature tubes may not be battery types.
This list is biased by the tubes that I have encountered during the repair of the many tube amps that have come to my repair shop. At the bottom of this page you' ll find some links to other tube datasheet sites in case you can' t find what you' re looking for here. In reading Schade, 1 every tube ama- teur should see what a masterpiece the 6L6 was in tube history ( and to my knowledge there is no solid- state four- terminal equivalent). The KT88 is a tougher 6L6, something like two in paral- lel. But the 6LW6, 6LF6, or even the 30W 6JE6 ( the MC- 3500 output tube) behave like tougher KT88s. NOS 6BQ5 and EL84 tubes are internally grounded at pin 1 and they will damage an amp designed for the Russian tubes if used!
6p21s tube datasheet
Check with your dealer to make sure you can use NOS 6BQ5/ EL84 tubes if your amp comes stock with Russian tubes. Russian 6N1P tubes SOMETIMES can be replaced with 6922, 7308, or 6DJ8 tubes.
