Selling a set of  two AM-7238s, one MT-6353, and two matching cables to connect to AM-7239 as in the first photo. 

This set will allow 50W output from the upper RT1439 in the last photo. The lower RT1439 uses the AM-7238 on board the AM-7239.

I tested these as in the last two photos.

The matching cables are extremely difficult to find.

Note: The whole system in the last photo is not for sale. Only items in the first photo are for sale.

Free shipping via airmail that takes 7-14 days to most parts of the world from Korea.

Some remote regions may take somewhat longer.
