Hi, I have a similar question. I have a pair of Telefunken 12AT7 and a pair of Mullard 12AT7, where should I put them? In the first response, it seems to suggest V3,V4 should match and V6,V7 should match. However, from other places, I read that V3, V6 are output drivers, one for each channel. V4, V7 are cathode followers, one for each channel.
In order to balance left and right channel, does that mean, I should put one matched pair In same brand in V3, V6; another matched pair in same brand in V4, V7?
