Good call Tom, you hit the history right on the head. That was early Advents entire business model. Basic, solid, ALMOST audiophile gear for people that would never buy expensive gear. I bought one when I was 17, around '74 or '75 when they first came out, only made in Mass, with silver faceplate, along with a set of the first Small Advents in vinyl to go with my used Dual 1219, all from the audio store Sounds Incredible, in Danbury, Conn. I WAS their target audience. I was in sonic heaven, especially with headphones. No one I knew had a decent sound system, cerrtainly not anyone my age. I cut a lot of lawns, cleaned a lot of pools, and carried a lot of lumber and bricks to earn the money for those pieces. I eventually, in college, bought a Marantz 170DC and use the 300 as the pre. Sold all my gear when I graduated as I needed the money. I picked up a 300 maybe 6-7 years back for $20, black face, did a re-cap on it, and thought I'd enjoy it for nostalgia sakes. And that's about it. Does garage duty now, with a pair of Klipsch white plastic bookshelf speakers given to me for free. I still get a warm feeling/chuckle when I use it, but my McIntosh C33s walk all over it and stomp it flat. As do any of my other receivers. The DIY homemade MM phono pres on AK absolutely embarrass the crap out of it.
