Default Dual Op Amp adaptor not working - help ?

Just received a dual op amp adaptor on a brown dog that doesn't work.
I have two OPA 627 AU's and Audio GD Earth and Sun v2 - in single L & R units and neither of them produce sound.

With Audio GD units there are loud pops and with the single 627's nothing at all.

I have been successfully useing a pair of minature 627's on a brown dog that work very well but I particularly wanted to try the Audo GD modules.
It's for a pre amp by the way - OPA amp / diamond buffer type.
I checked I got the pins ( pin 1 etc ) the right way round first before fitting.

Baffled as usual
Any ideas welcome

Thanks
Andrew
