Date added: 10/09/2012 Solid-state equivalent of 6L6 and 12AX7 tubes from AMT Electronics
Presently, AMT Electronics engineers are testing prototypes of popular 6L6 and 12AX7 tubes solid-state equivalents. Our goal is to create a reliable identically sounding analogue that doesn’t require recurring replacement and has constant parameters which remain so all the time in spite of how hard operative conditions are.
AMT Electronics 6L6WS (WarmStone)
Solid-state pentode 6L6WS is an analogue of popular power-amplifier 6L6GC tube that reproduces its vacuum prototype characteristics. Special emphasis is laid on increasing reliability of work in extreme conditions that are common for guitar amplifiers.
AMT 6L6WS has control and screen grids leads, cathode, anode and 2 heater leads just the same as original 6L6 has.
Max characteristics of the solid-state pentode AMT 6L6WS
- Maximum plate and screen voltage - 800V
- Max plate dissipation - 50W
- Peak plate power (t<100ms) - 120W
- Max Plate Current - 1.5A
- Cathode-to-heater potential ±200 V
- Max Screen Grid current - 30mA
- Heater Voltage - 6.3V
- Heater Current - 20mA

AMT Electronics 12AX7WS
Dual triode 12АХ7WS is a solid-state analogue of the popular 12AX7 (E83CC) vacuum tubes. Its characteristics remain constant through all the operation time, where vacuum tubes require regular replacement due to characteristics degradation.
Heater voltage is 6,3V or 12,6V depending on heater leads connection type.
- Max Anode Voltage – 400V
- Max Anode Dissipation – 1W.
- Max Anode Current – 10mА.
- Max Cathode-to-heater voltage – 350V.
- Heater current – 10mА
- Amplification factor – 100
- Trans-conductance – 2mA/V
- Grid to plate capacitance – 1,5pF
- Input Capacitance – 5pF
