Default Re: Hope to start an audio amp with CV415/CV4046/TT15

Hello
I've recently built some amplifiers both single ended and push pull and attempted to use an EF91 in the input stage. Having a few new and used, every one was microphonic and rang like a bell so I would use ECC83 0r ECC81. If you only need one half the other can be left unused or you could paralell them.
Just my thoughts and good luck with the project.
