Hello,

Thanks for the bandwidth here re: the AG-35 preamp. I found one for sale and expect to receive it soon..

I've been searching Google for a schematic, but so far no luck. I'd like to know if anyone has one, or can answer a simple question?

Q) Does AG-35 has a built-in voltage regulator? If so, does anyone know the part number, or the minimum / maximum input voltage?

I did find an AG-35 owner's manual online, and it indicates that the current draw is 200 mA. I'd like to know if I need to build a new bias tee, or if I can get away with using my AO-40 era bias-tee to feed power to the AG-35? I'll have to dig it out, but if memory serves, it delivered 18 VDC at 300-500 mA?

Thanks for any help or suggestions.
