I finished my ST70 rebuild (VTA board) & I'm loving it.
Now I have a Dynaco PAS3 that I'm looking to upgrade. I will be purchasing the new power supply & the "Z-mod" circuit board, plus other parts. I don't have a turn table & will not need a phono board.
Question 1: Is it advisable to totally omit the phono board & save 2 tubes ?
Question 2: If not, can I use the "Z-mod" board alongside the current, original phono board ? & do I still need to waste 2 tubes ?
