Thanks for all the info. I got mine in on Friday and tried it out. One of the quad was redplating intensely. Funny as it is, that one showed pretty severe signs of over work and I managed to put it in the very socket it must have been in before lol. I replaced both Good Alls with a couple NOS EMs and popped in my set of EL84Ms and we're good. I bought a little U-Turn RIAA preamp a while back and was dismayed by the output with one of my turntables. I need to build up my phono/driver pre and see what this thing is like, though there is that unused socket on the chassis that's begging for a driver. Any tips? I was thinking about a 12AT7 but being new to hifi I'm curious about the placement of the volume control. I was thinking cap isolated at the front. Ideally I'd want to follow the tube with that control, but I don't want to bother the impedance of the PI entrance. I've seen and read a bit about adding a 100K control on these Mag chassis, but isn't that a bit low? I heard one in use on YouTube and it seemed alright. What's the general take on that?
