Can anyone recommend a single stage circuit for *buffering* a signal for a sub-woofer output?
Currently building a S.E. 2A3 amp using one gain stage using the 6SL7.
I'm devoting the second half of the 6SL7 as a buffer stage for a sub-woofer output.
Need inversion so I can't use a cathode follower which is non-inverting.
Don't really need any gain. I don't think so anyway.
Thinking about a 'conertina' or split load stage to where I just take the signal off the plate with no gain.
If I set it up as a more typical gain stage, then I guess I'll need a resistive divider of sorts to bring the signal back down to 'line level'.
Probably will need a RC filter of sorts to capacitively couple it to the sub-woofer.
Any suggestions?
Thanks,
Gilbert
