View attachment 2211728 When I bought the place, there was another persimmon in the back yard, but it must have been a male also, because neither one produced fruit. Or maybe it was just sick, because it died within 4 or 5 years. Cottonwoods are the same way. There were two in the front yard and the male didn't produce cotton, but the female would turn the yard white.
I have an EL34 based stereo amp. NOS were mucho dinero. I've had good luck with Russian tubes vs Chinese, but wonder what supply is like given the current state of affairs. Its been a while since I bought a set.
