If the Champ II is like many Clearaudio TT's with pod-mounted armboards, you can have an armboard made to accommodate virtually any arm. You have to follow the arm-pivot-to-spindle-center distance for that specific arm, adjust the cartridge overhang and align the cartridge at the correct null points and you will be all set. I recently went through this process on a Clearaudio Ref TT for a Zeta arm with a brass armboard machined by a machinist friend. This worked incredibly well. Only potential issue would be height where you have an arm that sits high above the LP. For this, the position where the arm mounts to the board would need to be lower than where the board mounts to the TT. I have seen such designed boards used on Clearaudio TT's for this exact issue.
