Yes, I was referring to the P09 and no I have not used it personally as I have a Marchand XM-44. However, both the Marchand and P09 use a standard Sallen-Key topology with OPA2134A dual op-amps. The power supplies are also very similar. I bought the Marchand over 10 years ago when I was more of a nubie but if I were to do it today I would definitely use Ron Elliott's board especially since Marchand no longer offers kits and the price is more than double of what I paid.
