In search for 805 tubes other than Chinese made
Anyone knows where to get a nice pair of 805 tubes (less than say $800)? It seems that Shuguang/PSvanes 805 tubes are the only brand I can find. I'm not against them but wonder if other options are available. I only could find a single RCA 805 tube but I need a matched pair.
