How do I reduce gain on my preamp?


I have new pair of speakers that are much more efficient than my old.

I called AR and they told me what values to change and faxed me a schematic. Thats customer service!!
Consider yourself lucky to be dealing with a company that's willing to share this info so you can do it yourself. When I asked AES if it was possible to reduce the gain of my AE-3 DJH, they quoted $125 and no mention of the final gain. It was like pulling teeth to get vague details. I've asked repeatedly if their modification would be attenuation resistors or a change to the original circuit. No reply to that question. How's that for a company that built their reputation on kit building?! AR, on the other hand, has never been a kit company, and yet, look at how accommodating they are.
