2018年12月31日 · With 6N7 you can't get to 1/10th power without grid-current, cap charge-up, blocking. The advantage of transformer coupling is that at one time a lump of iron was cheaper …

The 6N7 looks to be a great tube for making a mid-power push pull triode amplifier. Nothing much is said about it. The plate to plate resistance is only 5K, so a wide variety of OPT's can be used.

2021年1月1日 · The 6N7 was used as the intermediate tube in the speech amplifier section of the Globe champ 175 (between the 6SJ7 and the PP triode connected 6F6's). That rig always got …

Metal type 6N7 and glass-octal types 6N7G and 6N7GT used in output stage of ac-operated receivers as a class B power amplifier or with both units in parallel as a class A amplifier to …

2008年4月23日 · I am interested in building a PP amplifier class B with 6N7. The signal inversion made by interstage transformer. Driver stage with 6N7 with the two section in parallel.

2016年3月6日 · Here's a schematic of an audio amp that uses a 6N7 as a phase inverter: And another: The preamp and PI stages in the first amp aren't much different in layout than the …

Common type USA tube/semicond. Metal type 6N7 and glass-octal types 6N7G and 6N7GT used in output stage of ac-operated receivers as a class B power amplifier or with both units in …

2010年8月28日 · The 6N7 is an ancient tube (of course) and the NOS ones I bought are what crapped out. The amp has likely 4 or 5 hours time on it since I put it together. 6N7s are cheap, …

It is designed to operate in push-pull Class B2 with zero grid bias or quiescent push-pull. The anode to anode load is given as 8,000 Ohm. It is specifically an audio power valve capable of …

2020年10月12日 · The 6N7 is a double triode. Both triodes have the cathodes internally connected. The tube was designed with two applications in mind. One of them a Class B …
