The 100w 2x12" Lab Series L5
The Lab Series amplifiers were the result of a collaboration between Norlin companies, Gibson and Moog. The L5 was the first and best selling model of the series, aimed at competing with the Fender Twin Reverb. It was a two channel, 100 watt amp with spring reverb and two 12" speakers. Controls were as follows. Channel 1: bright mode, volume, bass, midrange, treble. Channel 2: bright mode, volume, bass, frequency, midrange, treble, multifilter, reverb. Both channels: compression, master volume. For a description of these controls, see Lab Series controls. Each channel had two inputs, for hi gain pickups (top) and lo gain pickups (bottom).
Channel 1 controls: hi/lo input, bright mode, volume, bass, midrange, treble.
Channel 2 controls: hi/lo input, bright mode, volume, bass, frequency, midrange, treble, multifilter, reverb
The compressor and master volume work on both channels 1 and 2
The two 12" speakers. Note the codes around the rim: 137 7942. 137 signifies that these speakers were made by CTS, with 7942 a date code. This decodes to the 42nd week of 1979.
