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.

:sam: :guinness:
 
According to the sweeps in the original manual - what appear to be max settings:

High boost in sharp 19dB.
High boost in broad 10dB.

5k cut 19dB.
10k cut 18dB.
20k cut 16dB.

Low cut 20dB.
Low boost 16dB.
