A real stroll down memory lane. I remember, as a poor university student, lusting after a ReVox (I think a B77).

Also somewhat sobering to read the specs.

Any idea to review one of the "new" reel-to-reels out there?

Thanks for bringing great articles like this back to life.

This is an interesting nostalgic article on a piece of equipment used in archaic recording schema, but (aside from narrow use special effect of using tape saturation to apply dynamic compression) it makes no sense to chase after it or anything like it now for general use in audio recording and playback as its performance has long since been eclipsed by the performance currently available on moderately priced AD/DA recording/playback hardware such as Lynx Studio Technology's E22 and E44 family of PCIe sound cards.

..were very different animals from the G36, and much better machines. They had addressed virtually all the complaints JGH expressed regarding the operation. And, they had made a big upgrade in the transport by doing a direct drive capstan system with servo control. They also made serviceability far better by using plug in cards. Of course, electronics were all solid state, not tubes, and this also improved on the noise specs. The G series is great for nostalgia buffs, and certainly built like tanks. But all the machines: Sony 777, Tandberg 64, and Revox G36 were pretty much obsoleted by the next generation of models from these manufacturers. I worked on all of them, and a lowly Sony TC 366 that sold for a couple hundred bucks could easily outperform a Revox G36. It was just a matter of newer technology filtering down market.

Have you enjoyed any of these recordings?

All-tube recording chain (if you go the LP route, anyway).
