Title: 6EM7 what are they good for.....
Post by: TIMBO on November 05, 2021, 03:49:54 am

Hi guys, Got a bunch of these...
Can they be used in a low watt push pull?
Maybe something like Robs micro Bassman.
Thanks

My thought is probably not since the tube is comprised of a hi mu and low mu unit in the same envelope.  https://frank.pocnet.net/sheets/049/6/6EM7.pdf (https://frank.pocnet.net/sheets/049/6/6EM7.pdf)


Guess you could use two of the tubes though for a low watt push-pull amp .

Something to start to go to a small guitar SE amp
