2013年4月22日 · Bas, try searching on 6P1P-EV instead. I built two SE amps with it, "FireFly Single Ended Tetrode" and a PP amp "Sven 6P1P PP". In addition there is info in the Meng Yue Mini thread. I just looked up the Sven 6P1P PP Amp thread, and that amp has been running for three years now as the main upstairs amp. I've never gone back and touched anything ...

2025年2月20日 · P1P（西里尔字母：6П1П [1]；中国型号：6P1）是一种已经停产的束射功率管。 它曾在苏联、中国广泛生产，与美国的6AQ5和6V6 [3]，欧洲的EL90类似。 由于6P1P是小九脚的电子管，与6AQ5/EL90等小七脚电子管不同，因此它不能直接替代6AQ5/EL90。 不过，在改变管座接线后，6P1P可以正常工作在为6AQ5/EL90和6V6设计的电路中。 6P1P有一种长寿命军用版本6P1P-EV（西里尔字母：6П1П-ЕВ 中国型号：6P1-J），它的参数大致相当于6AQ5W。 存世 …

The 6P1P (Russian: 6П1П) is a Soviet-made miniature 9-pin beam tetrode vacuum tube with ratings similar to the 6AQ5, EL90 and the 6V6. Because of a different pinout (a 9-pin base versus 7-pin base) than an 6AQ5/EL90, it cannot be used as a plug-in replacement for these types; however, it will work in the same circuit with component values ...

2020年11月3日 · My question is what impedance transformers will I need? I've read that parallel tube designs like 1/2 the normal rated impedance for SE use. I've also read this tube, and it's US electrical equiv the 6AQ5, like 5K in an SE amp, so does a …

2025年3月10日 · I've got some 6V6s & 6P1P-EV valves and a couple of SE 9K:4ohm transformers. Can someone suggest a schematic for a 3 - 5watt amp?. The transformer is a bit high in impedance but there should be something.

The 6P1P is a fantastic tetrode, and cheap! Basically a 6AQ5/6V6 in a 9-pin bottle. This gets you lots of transconductance (the total Gm will be the sum of the valves being paralleled) at lesser drive voltage than many of the big-boy tubes would require.

2020年10月21日 · The 6P1P-EV with a 12 watt plate dissipation it can provide pretty well the same power output in a simple SE class A circuit as the much more expensive 6BQ5. Below is the spice circuit that the design was developed with.
