Hi I am looking for a PHONO amp circuit based on low noise transistors NOT opamps .
Can you offer a suitable link to that ?
Thanks EC

This should be perfect for you - way over the top !!!
If you ever build it please let me know if you think it's any good.

Wa-a-a-ay over the top! He should have built it with toooobs ;-)

The 'signal processor' section lists manuals with schematics of the Hafler products from the 70s and 80s. I still have a DH-101 preamp which has a decent phono preamp - discrete.

Many tahnks guys

Yes i looked. What a piece of crap. Over 10 times too many transistors; all the resistors to support them adds noise. I can beat it in 6 transistors, 4 in a real cost pinch. I do not have any of my old schematics handy, and it is easier to recalculate than to dig. I will fix you up with the base circuit if asked, but you have to calculate all the parts.
Absolutely dead on. "Designed" by someone right out of toooob school ;-)
