re: 767

Additional models to list: The 700 series comprises models 750 (deck only, no case) 753 (50 Hz version of 750), 755 (750 with Pause control), 755A (755 with automatic EQ switching), 760 (750 with built-in amplifiers), 761 (760 in larger case with two 414 loudspeakers), 766 (GSA version of 761), 767 (similar to 761 with Pause control), 768 (PX version of 761) and 778 (Navy version of 761). Many models have 1400 series equivalents. The 1400 series has automatic reversing for bi-directional playback. Belts are still readily available and use much improved rubber formulas eliminating the original problem of belts deteriorating into tar-like goo. When properly set up, these machines can offer stellar performance and very good reliability. Note: many 750 were sold with vinyl covered or wood case, fitted by the dealer. It is common to find 750 installed in case, even though deck did not include one. 700 series was discontinued in 1971.

re: 767

The deck used in this model and a few others, came on the market somewhere in the mid to late 1960s as Ampex's entry into the lower priced home/consumer market. Up until then, Ampex tape units were high buck, professional models primarily for radio stations and recording studios.

I worked in the repair dept of a high end Audio component store in the late 1960s and got to work on some of these. The electronics and heads were excellent (in my opinion), but the mechanical drive was problematic. I remember two very large belts, which actually looked more like huge O-rings, being round in cross-section. These belts had a short life and most mechanical problems were cured by changing out these belts. This was a disappointing quality/reliability item for the high end Ampex name. I don't know if the belts are available any more now (2017).

I just bought one of these 767 decks that had been lifted out of the enclosure, and with no speakers or microphones. It has Mechanical issues and I will see if I can breath life back into it. If not, I'm only out ten bucks.

Ampex Model 1461 I own look exactly like the picture in this manual, that mean this manual is best apply to model 1461, model 767 has the same operation and lay out but without speakers.
