AGI 511 Preamp... GEO JAP Are you out there?


First-time poster here, just signed up. Great forum!

I have recently acquired a very impressive AGI 511 Preamp, circa 1974.

Until now, I have been using the highly respected TRANSCENDENT SOUNDS GROUNDED GRID preamp designed by Bruce Rozenblit, which is still my go-to preamp.

But the AGI is truly impressive... Spectacular even!

I am keen to hook up with GEOJAP (Jason) or any other members who have experience with the AGI 511 Preamp and any potential mods.

Appreciated.

I had one back in the day.  I was well-built and sounded good to me at that time.  Can't say I'd have much interest in one now. 
I had the 511 in use for a year back in 1977. It was connected to a Son of Ampzilla and Infinity Monitors with Walsh tweeters. The 511 is an excellent preamp competitive with today's four-figure gear!
