Rewiring G1176 output transformer for more gain

[fum]

Hey there,

Looked around and saw reference to this, but not the actual info.
Here's how to rewire the output traffo on the G1176 for more gain. Props to Swedish Chef for this:

I modded all of our G1176s by re-jigging the way that the o/p tx is connected up.
Download the spec sheet from Lundahl; it'll make this easier.
Connect pins 2 and 4 and use these as the i/p. Connect pins 5 and 1 to 3 and make sure these are grounded. On the secondary side, connect pins 6 and 9 then use pins 10 and 7 as + and - o/p.
This gives something like 35dB of gain or there abouts...
I was also getting a load of 100Hz hash on the audio gnd so I isolated the p/s gnd and Starred it at the chassis. This made it very quiet!

And here's a link to the datasheet:
