1176 and OEPs, what ratio did you choose?

I need to stuf my second Mnats J ver. board with OEPs but can't figure out what is the best ratio for this one.

I mounted Ludahls as 2:1 IN and 1:2 OUT ...

Hi Pususha,

I think for OEP transformer the ration is 1:2. You can check at Mnats site.

Hello Dinesh, I red Mnats pages but I am still not sure...

BUMP :roll:

I bought four OEP A262A2Es to use in my stereo 1176 as listed in the bill of materials here:

As far as I know you can change the ratio of these transformers from 1:1 to 1:2 by flipping them 180 degrees in the mnats PCB before soldering - more info here:

It appears that the best orientation is 1:1 on input and 1:2 on output, when I get all the components together to finish my 1176 that's the way I'll do it. :green:

Thanks. I will do the same.

OK, just to be sure...

When using OEPs, R* and R*1 are left out, right?

I still don't know about the C*, C*1, C*2 caps... are this left out too or what?
