How to make a RCA output for subwoofer on Reisong A10

[RV1938]

Hello, Thanks for the schematics 🙂 but I prefer to not interact with output transformers, I'm trying a new schematics found on a book about aop

Try this passive circuit, it works!

It connect to the output transformers, 1/4w resistors should be adequate. If you found the output level is too high, reduce the 1KΩ resistor value.

This is the type of connection I used for my subs, but did it external from the chassis from a secondary speaker wire. Super simple and cheap. I increased my 10k resistor to 13k to drop the level a little more.
