new member, old question

Post by ptamp » Sun Feb 19, 2017 11:16 pm

I'm helping a buddy wire up a Metro jtm-45 .
He upgraded to a MM 045rs-l OPT.
He wants it to be 4 ohms, (can't use the selector with these).
The schematic shows the NFB coming off the 16 ohm tap.
There is no 16 ohm tap and MM said to just wire it to the 4 ohm tap.
Do I need to change the NFB resistor by a factor of 4? Bigger or smaller.
I'm sure everyone who has used this tranny has run into this issue.
Any thoughts?....thanks Larry
