I have built Leach amp some months ago and it works incredible.
Now I thinking about using it as integrated amp( passive preamp + Leach power amp). I try this combination with simple plastic 100k pot, but it hasn`t got enough gain.
So I`m thinking about to increase gain (of the Leach amp) for about 6 dB (my CD player has a 2V rms output and tuner about 600 mV) to put maximum from amp.
It is possible to increase gain? I am worried about feedback network!!
Thank you for ideas!

Preamp For Leach Amp
Dr. Leach published a preamp construction article and design "Construct a Wideband Pre-amp" in Audio magazine, sometime in the 1970's. I listened to it being played through a (my) Leach amp and was quite impressed.
Let me know if you find any of those "Gain Pots". Quite rare, I believe
