This edition is the third and final version that was used from roughly 1965 to 1967. The Gibson Skylark is an underrated small amp from the late 50s and early 60s that many vintage collectors are focusing on as a viable alternative to pricier Fender equivalents.In 1965 and 1966 Gibson gave the Skylark another major design overhaul. These are commonly referred to as "white panel" amps. These are notable for their rough black "elephant hide" tolex, silver grill cloth, and Fender style 1-10 marked knobs (see Figure 6). These featured a 10" Gibson Ultrasonic speaker. The tube compliment for the GA-5 in this series is: 1-6EU7 (pre amp) 1-6BQ5 (power amp) 1-6X4 (rectifier) The GA-5T used: 1-6EU7 (pre amp), 1-6C4 (phase inverter), 2-6BQ5 (in a push-pull power amp design) solid state rectification via 2 diodes. Control panel layout is: 2 inputs, volume, treble, bass, speed and frequency (tremolo), and a rotating on/off knob with a small pilot light above it (the fuse holder is on the back panel). It is notable that this design used a box type chassis that is attached to the cabinet by screws through the top like the 60's Fender amps. Also, the tubes hang down from the chassis.
