what have I done to my alpha 5 cd - help ?

[AndrewGM]

I have been twiddling / upgrading my alpha 5 plus for a while now
with good results.
Yesterday I ordered 2 OPA 627's for the IV and decided ( why I don't know ) to put 8 pin sockets on the dac board so I could just snap them in when they arrived.
I put the OPA27 back in to the IV sockets and switched on.
( I have Audio GD output stages in place of the standard op amps )
Switched on and nothing - I examined the OP AMPS and found I had broked a leg on one of them so I fitted the OPA 134's I had spare... and still nothing.
I then noticed the regulators ( the ones without heatsinks ) were cold as they are normally hot. I checked the solder pads and found them to be loose with the whole regulator rocking. I re soldered them which fixed the rocking.
Switched on and still no sound but this time a burning smell from.
the op amps - they were very hot. Switched off straight away.
The player reads discs and moves from track to track - it's functions are not afected.
Just no sound and hot op amps.
Anyone out there been through this ?
Any advice welcome please !
