Designed for heavy duty use, the Demeter VTHF-300M is equally at home in the studio or on the road. Its all tube high fidelity design rivals and surpasses the sound quality of many of the so-called audiophile amplifiers, yet sells for substantially less. Its awesome power (300 W RMS pentode/150 W triode) can run any speaker through its paces with the accuracy, definition and fullness that only tube amplifiers can deliver. Featuring a custom designed and high current bifiler audio output transformer, regulated B+ to the preamplifier section, individual output tube bias for long tube life, pentode/triode switch, variable feedback control, heavy duty binding posts, gold plated RCA input connector (1/4 phono and Jensen balanced 3-pin also available), optional two speed fan, toroidal power transformer, solid power supply (880 mf @ 800 volts), Demeter selected tubes, a beautiful heavy duty aluminum and steel chassis, all hand built construction in the U.S.A. using only the best quality components.
