The L1500 is running in nicely. It still takes a long time. My sound stage and detail has turned. Not quite all there yet. It may soon run with the"big dogs.'

This is the tube complement for the L1500D3a or equivalent × 2
7233 × 1, 6485 × 1 (Voltage Regulator)
This is a four sided picture of my preamp. Pay particular attention to the rear. The fornt side has eliminated the chrome volume control for a knurled motorized volume knob. The little happy face on the left that looks a smiley face is actually a voltage meter to detect tube wear.

Really good looking piece Greg, mine took about 750 hours to get right and is still improving after more than 2000 hours. Mine is not the L1500 but I think the transformers are what require so much time.

Greg, The absence of balance control seems normal, perhaps that's because I owned an Aesthetix Callisto for a decade and it didn't have one either.
Sure, the Callisto dual volume controls allowed the user to set separate gain per channel, but I never felt the need to do that. Either my system is well balanced or I accept differences in output from channel to channel as normal sound in the recording.
As for boarding a plane this summer, I hope you mean it. If your trip puts you here during our Tuesday audio meeting you can meet others in the group.
