The 407 tape deck was the first audio consumer product from a company previously devoted to industrial products. It was a high-quality,well-engineered machine with auto-reverse (on playback only), three motors and four heads (the fourth was for reverse playback).
Other features included sound with sound, echo effects, auto tape lifters, direct off-tape monitoring, solenoid-operated tape controls, auto shut-off and mic/line mixing.
In the opinion of one of our members that owns four of these, you can count on the fact that the transport will likely have some issues that need to be sorted out.
The solenoid operated functions have a small delay, which is common with some of these earlier technologies like the Pioneer RT 2022. Capstan motor only turns on when play or record are engaged

Every once in a while we come across a product which so clearly stands out in its class that we must evaluate it relative to much more expensive equipment, otherwise only superlatives would be found on this page. The fact is that Astrocom/Marlux has produced a terrific tape deck.

Especially notable are its low wow and flutter, low distortion, excellent signal-to-noise ratio, absolute meter accuracy and smooth extended response for both playback of prerecorded tapes and for record/playback of tapes made on it.
