And BTW, you can pull the four phono tubes and it will work fine.

If you have the unit facing you - and look down from the top - the four tubes to the farthest RIGHT (count from the right side toward the left) are the Linestage tubes.

Neal - I used to be a dealer for this preamp when I had my store in the late '70s. If you care to send me your 'phone number, I'll call you during my "free weekends". Pretty sure I have a piece of literature on this unit. Don

Here's what I would do. Play your source. Keep gain set low on amplifier. Turn off preamp. Take out one tube. Turn on preamp. See if source still plays. Repeat process one tube at a time and see which ones can be removed without stopping the sound. Replace the ones that are necessary for sound from your source.
