No, you don't. However using two chokes will improve the channel isolation, and improve cross talk performance. It looks like the RH807 was intended for stereo, and being a single-ended design, there is no AC nulling such as occurs at the center tap of a PP OPT. In this case, it would be wise to split the RLC ripple filter so that each channel has its own ripple filter.

Yes two chokes will improve cross talk that i understand, i was trying to save some $$ with only one choke but wasnt sure, i have built 2 RH84 with great result so i was planning to stick with the RH84 power suply but with higher voltage power trans if thats possible.
