6N1/6N3 substitution

woodturner-fran · 30th January 2007, 11:25 PM

Hi all,

wondering if someone could double check me here.

Can I substitute a 6N3 (5670) for a 6N1P once I account for the different pin outs on the 2 tubes?

No. They are differen tubes. 6N1P were developed to replacs 6N8S (6SL7), 6N3P were developed for high frequency amplifiers.

There were so called "Otraslevoy Spravochnik" books for usage by developers inside of the industry...

Thanks for that link, I had come across it before, but never really took note of it.

So if the data sheet didn't tell you specifically that the 6N3 was designed for HF amping and the 6N1 for low freq amping, is there any way that you could tell from the electrical characteristics?

Internal capacitances would be one clue.

OK,

that just tells me that I really haven't got to grips with this at all!!!!

So I'm gonna embark on a period of research and hopefully come out smarter at the other end.

Thanks for the responses, the help here is really great! I'm about to order a book or 2 as well. Hopefully one day I can become a contributor rather than a taker! Now, anyone any turntable Q's I can help with that!!!!
