Hello - I just completed my first kit (Mainline), had a blast with it, and would like to get an Eros next. Can someone confirm the correct step-up transformer for my cartridge? I'm using a Sumiko Starling. Their website rates it as 28Ω internal impedance, >100Ω load impedance, and an output of 0.5mV. I'm thinking the Sowter 9570 would be correct? Also, would I need to order additional resistors as well? thank you
