The L260D BTO is the guitar head of Garnet's BTO series (Big Time Operator, not the band Bachman-Turner Overdrive), sharing this power stage with the B260D bass model. The sheet covers only the final stage and supply: a 6AU6 tremolo oscillator with an on/off switch modulating the bias, a 6SN7 driver transformer-coupled to four fixed-bias output pentodes, and a choke-filtered silicon supply with standby and a ground-reverse switch.
