Power amplifier enclosure

A cassette tape player (11) has an integral combined tape guide and stripper (32) which is mounted adjacent to a capstan shaft (26) and has an end portion (52) that extends beyond a free upstanding end (38) of the capstan shaft and effectively forms a guide plane for insuring that when a cassette housing (12) containing a tape (15) is inserted into the tape player, the tape will be positioned between the capstan shaft and a pressure roller (29) which is selectively, linearly movable toward and away from the capstan shaft. The tape guide and stripper is fixed to the tape player frame (19) and includes stripper portion (54, 55) which partially surround the section (39) of the capstan shaft that will contact an inserted tape, but still permit selective engagement with the movable pressure roller such that the tape will be pressed between the capstan and pressure roller while the stripper portions prevent the tape from being wrapped around the capstan shaft.

Combined cassette tape guide and tape stripper

A rotatable link coupling mechanism with a first disc attached to one end of a radio tuner shaft, a second intermediate disc, and a third disc attached to the end of a moveably positioned drive shaft. The first and second discs and the second and third discs are linked together respectively by a series of elongated coupling links which provide rotational coupling between the drive shaft and the radio tuner shaft.

Rotatable link coupling mechanism for radio tuning shafts

The assembly has a tuning control shaft which is adjustable over a range of positions to conform to a range of tuner designs. An adjustable guide bracket for the manual tuning pinion gear allows the pinion gear to be positioned along a radius of the crown gear, allowing use of radially wider gear teeth on the crown gear. The clutch-declutch assembly is unaffected by movement of the pinion guide bracket and the entire tuner control and drive gear assembly is preassembled and preadjusted, then positioned with one locking nut.

Adaptable tuner assembly

An extremely rigid support structure for mounting the tuning coils and for guiding the movement of the core carriage, includes a coil case which is a one-piece molded element having integral indicator guide slot and core carriage guide rods, with the guide rods being fastened to the front portion of the structure by means of screws which pass through the front portion and mate with threaded apertures in the guide rod ends which are in abutting relation with the front portion.
