In the 1970s I converted a Heath SB220 to 6m. It was from a QST hints and kinks coloum and only changed 10M, 80-15 remained unchanged. . I had so many requests for the info I had a sheet printed to send to people, now I can't find the info myself!  I am in a situation now where I only have 120V to the shack and an SB220 at reduced power makes more sense than trying to convert just 10M of an AL80 or similar PI-L.
P.S. later I converted it  to 6M only with vacuum variable etc and didn't see the value of losing 80-15 for another 100 watts.
