www.pispeakers.com/Components/PSD2002.pdf - scew mount. I never really used it (it's got probably less than 2 hours on it), .. so it's practically brand new (operationally and cosmetically) guaranteed. I'd like $35 for it. Interesting trades/partial trades also considered (2.5 V filament transformers, filter chokes, 45 DHT tubes ...)I'll be at the LSAF this Saturday, in case that would be convenient for any potential buyers.
TIA
