I am still searching for a power supply (PP-445/FRR) for my RBS-3 receiver, so I am wondering what differences that are in the CCT-2023 supplies and the PP-445/FRR? I understand that some of the RBS supplies had a 12v filament string (RBS-3 has 6v), but what about the other voltages? Gene, WØQFC Spring Hill FL Lafayette Lodge #91 A.F. & A.M.
