Anyone here have the Au-5500, Au-6600 or Au-7700? Is the Au-6600 harder to find or sought after? Mine has been fully overhauled with new caps, transistors, and select resistors. What's next? Think i'll replace the rca inputs with better ones. I am using an early pair of dynaco a-25's with this amp and it is sounding really nice to me!
Got to switch out the a-25 crossover caps to new solen ones as well and see if that makes a difference. Is there a sure fire test to see if speakers are not blown and are working as they should? I can play a sine wave through them, in all frequencies, sweeping from 10hz to over 20khz and i do not hear any crackling or breakup...
I can measure the resistance of the driver correct?
 
Yep. Have all of them. Great sounding amps. The 6600 as well as its later brother, the AU-6900 were a bit rare.
 
There are only 7 on file. Please post the serial number for the database. Click on the link in my signature block.
