Hi all,
I ran some sweeps on my Pultec yesterday and everything seems good except for the 100Hz boost curve, which looks pretty much exactly the same as the 60Hz curve. The 100Hz cut looks fine. Also, the maximum amount of LF boost seems a bit small - it's ten dB instead of the sixteen on the schemo and the 20 I'm measuring in the HF boost. Any ideas?
Here's the schematic.
