QUESTIONS ON TUBES

Dear all Audiogon’s members:
I am new to the “tube” field. I just got a Chinese Mingda integrated amp to start with and which has 22 WPC. It came with 4 X 6L6, 2 X 6N1, 2 X 6N2, I believed should be all from China. A question is: if I would like to change/substituted above tubes, what other types or numbers can I do so? Thanks a lot for all your help to answer my question. Have a great day. ^_^

There have been posts both here and on AA that there are no substitutions for the 6N1 tube. So you may be stuck with the Chinese offerings. This may also be true of the 6N2 tube as well.

Thanks for the infomation. That helps a lot. At least I know where should I start from. By the way, regarding Frank's info, I saw some ad using 12AX7 and 12AU7 for Mingda's other model as pre-amp stage, should I try?
Once again, thanks for the answer ^_^

That, you will need to check with the manufacturer to see whether these tubes can be used. It might be the case where somebody had tweaked the circuits to accept the 12AX7/12AU7 tubes.
