Thanks for the warm welcome! @Daddyjt the speakers are home built, they consist of a line array tweeter, 26 tweeters per side, and then conventional 6 inch mid and a 12 woofer. The mid is a peerless and the woofer is an eminence kappa pro. I am using a single tapped horn kappa pro Lf for the subwoofer. It has taken tons of tuning but I am close to having it sorted out. @Turbo is that your goat in the profile picture? I have a 66 and a 69. @Brian_at_HHH the sansui is being used as amp only. The preamp was a bit of a rabbit hole. I bought some cheap tube preamps off of bang good, they were stereo and used 6j1 tubes. The short story is they were designed poorly. But I already had the good military Jan tubes I bought and sockets, so I built a point to point 6 channel tube preamp. To control the active part of the speaker crossovers I run a dsp.
