I have a 4-track 1/2" Ampex AG-300 in my basement, which was a stock Ampex model using the 300 transport and solid state electronics. It still works, more or less, although it needs a tune-up and some lubrication. I admit that I have not measured flutter or speed stability on it. But tape-to-head contact seems fine (based on reproduction of 15 kHz alignment tapes). My worry would indeed be flutter, mostly from the indirect drive but also scrape flutter. It gets worse when the rubber surface on the transfer wheel thing goes.... you can replace or recap the pinch roller but the big wheel is a problem. Words can't express how much time I have wasted trying to get flutter on those transports down to something reasonable, and using reels that are twice as heavy doesn't seem like a way to reduce flutter (although you do get twice the contact area on the capstan). --scott -- "C'est un Nagra.

Words can't express how much time I have wasted trying to get flutter on those transports down to something reasonable snip Despite all the hype about the "greatness" of the 300, they were really a PITA for flutter and speed. Back when you could get new rubber, you could spend hours rebuilding the capstan drive and at least get "as manufactured" flutter, but that only lasts so long. You still wind up with the speed accuracy issue, as well. Even when everything's in top notch shape...rubber, bearings, capstan finish...a 350 would still beat a 300 by almost half on a flutter bridge. What hype is there? I remember everybody upgrading their 300 transports to 350s as soon as they could afford to! And then... what were those aftermarket tension control units? Was that an Innovonics thing too? Tentrol? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
