Here I have a brand new pair of Shuguang 845C (metal plates), fresh from China. I waited almost a month to receive them; you can have them in a matter of days.
My reason for selling them? I found out, after the fact, that their plate dissipation is simply too low (70W) for my amp (100W, which is standard). If you have an amplifier that you can vary bias by a fairly wide margin then you can likely use them (but don't do like I did and *not* do your homework).
According to a handful of reviews (hit Google), these are THE Shuguang's to use...if you can. And I must say, of the 845A's and B's, these honestly look to be the most well constructed.
Buyer will pay actual shipping (not the price A'goN's calculator lists), and PayPal fees of 3%.
Thanks for looking! ~ Mark
