Preamp for Tim Mellow's 6C33C OTL

[flanagan]

hello,

any preamp suggestions for Tim Mellow's 6C33C OTL amp?

two channels needed, normal and phono preamps. i'm planning something around e88cc tubes, but not nessessary...

what do you think about this?

An externally hosted image should be here but it was not working when we last tested it.

what for phono?

thanks,
flanagan

What is the input sensitivity of the amp? If you need more gain just add a single triode such as a 6J5 to the "front" of the amp. The above circuit adds several tubes and caps in the signal path along with neg FB.

input impedance is 26k.

The 6DJ8 needs at least to run at 5 - 6 mA to be more linear ....
