JustinVG I missed your self-intro post when you first made it, but let me say again welcome!
I owned a Petrof upright for a few years (before getting my current piano, which is Yamaha C2 grand). The Petrof I had also had a really nice tone, there was something very unique about it, and its voice was what made me want to buy it. (I hope its current owner is taking good care of it!)
Anyway, I'm glad you found PT! ๐
