Excessive gain in OTL preamp

OTL Asylum

OTL, Output Transformerless Amplifier User Group.

I have a Single Power MPX3 headamp/preamp (SLAM SE Model). It is OTL. Is there any way to reduce the gain in the circuit, other than to attenuate? It has excessive gain as a preamp for my power amp.
Would reducing the gain of the input tube have any effect? What about the gain of the output tubes? Or reducing the output voltage? I can do these things very easily. It takes lots of different tubes and has a low voltage (for 6SN7GTs, and 5687s) and high voltage (for 6SN7GTBs and 6BL7GTAs).
I suspect these things will not really help. I need to kill at least 5dB! I have tried attenuation - Yuk!
