pre amp Anthem and Dynaco ST70


At last I have a pre amp Anthem pre 1L and a dynaco ST 70. I wanted to set up triode mode instead pentode mode. Besides, I would like to know about other upgrades for my dynaco. Can you help me?

Thanks

Have you replaced all the capacitors and resistors?
I would suggest that you do it - improves the detail 10 fold!
Get some good caps like CARDAS or ELNA...

Good luck,
