The Sovtek MIG-100H is a Russian-built 100-watt all-tube lead head. It is a single channel: High and Low inputs, a Gain control after the first 12AX7 stage, two more cascaded gain stages and a cathode follower into a Treble/Bass/Midrange stack, then a Master. A 12AX7 long-tail phase inverter with Presence drives four fixed-bias 5881s, with a choke-filtered bridge supply, standby, 4/8/16-ohm jacks and a line out. It was known as an inexpensive, hard-driving tube head.
