I find myself agonizing over capacitor values in the power supply of the ST-35. I have posted this same query on another site and got one response from a member who is also on this forum. It was advised to keep the 1st section lower than the 2nd. Dave's Lab (who inherited Audio Regenesis) uses values of 47-120-120uF, which is in keeping with a lower 1st stage. Diytube, in their version of this amp, uses 120-120-120uF. Dynaco uses 60-40-20uF in the original. (I'm leaving out the final stage since I'm using the Enhanced Fixed Bias and using a separate cap for this).
I don't see any need of going over 120uF in any stage, but I wonder what would be optimal values. Currently I'm using an 80-40-30-20 quad cap where I've strapped the 30 and 40 together for the 1st stage, to give me a 70-80-20uF set-up. The driver stage (20uF) might be a little wimpy, so I might reconfigure it to 40-100-30, or 40-80-50, or 50-80-40. As you see, there are several combinations available. How would you configure the 80-40-30-20uF cap that I have? And what would you use if you were doing a scratch build?
