I’m happy to hear that your Lino C 3.3 seems to be fixed. I did, however, charge my new battery overnight before using it in the Lino C3.3, and after playing one side flawlessly my Lino C 3.3 started acting weirdly again on side 2 and then stopped producing a signal entirely. And the indicator lights on the circuit board again indicated that the power supply rails weren’t connected. So, I hope this doesn’t happen to you.
Regarding the connectors, the dealer I have worked with for several years (and from whom I bought my amps, speakers, turntable, cartridge, etc. and now Sutherland Dos Locos) had the adapters made for me gratis. The RCA connectors are Neutrik spring-loaded NF2C Profi connectors, and the person who built them used silver wire to connect them to the XLR connectors and silver solder, and they have floating ground wires that connect to the ground lug on the back of each Dos Locos. I’m told they sound better than stock Neutrik XLR/RCA connectors.
Again, I hope your Lino problems are over, but if they’re not good luck in finding a replacement.
