??? Hovland Tube positions V4-V6


When I was replacing tunes for HP-200 tubes, I had a moment of dementia that I forgot positions of tubes in phono section: V4,V5 and V6 as to which one is for 12AU7 and which ones are for 12AX7.

Can someone please help with these tube positions ?

Also, would it damage the unit, it I run it without tubes in the phono section as I do only listen line sections ?


Thanks
