2A3 is the model number of tube. You can connect your 6 ohm speaker to 8 ohm output of your amp.

Monitor Audio RS8 應該係 89db/W @ 1m。
用 2A3 推應無問题。

如果得一枝2A3一邊 single-end 得3~4W, 有聲但無bass, 如果有二枝2A3一邊行 push-pull線路, 有十幾火,都應該可以推座地.

我曾用 1W x2 的 收音機 來推都無問題,仲 "鬼殺咁嘈" 添!
呢对 喇叭 想有中音就話難啲啫,低音?碎料喇!

845SE. Very very good machine. Power about 20W & it can drive most of difficult drive speakers. Your 2A3 & 6SN7 to be use for pre-amp (I already done).
