Front flap (left)
The SL-HF77 was a well specified Super Beta HiFi model. It was not released in the UK domestic market, it's nearest UK equivalent being the SL-HF100.
The machine is lower profile than the SL-HF100 and follows the design style of the SL-F30/60 series. It replaces the individual channel select buttons with an up/down pair of controls. The infrared remote is also slim like the SLF30/60 series.
The machine has provision for a sound only recording (this feature disables the video drop out compensator) which also doubles in enabling it to be used with a PCM encoder to give higher than CD quality digital stereo audio.
The front flap houses the following controls:
The SL-HF150AS compared to the SL-HF77This model can be directly compared with the SL-HF150 with the main difference being no Super Beta Hi-Fi.
The Australian SLHF150AS version has its TV output on VHF Channels 0 or 1 whereas the SLHF77ES has its TV output on UHF tuneable over the range channel 30 to 39.
Style variations are as shown in the pictures with the gold versus silver highlighting changes and the addition of "Super Beta" title to the SLHF77ES.
