Question about atra0427 OT connection

Box

Hi, I am assembling the a15mk1, but the layout and the schematic in the output part are different with this new version with the atra0427. Where I must connect the R57?

Thanks

Hi,
haven't you received the additional documentation for installing the ATRA0427?

Yes, I have received the additional document, but I'm mot sure. I must connet R57 between 8 ohm plug and ground in the same way of the old OT?

Yes,
only the connections at the output transformer have changed, all others stay the same.
