It was manufactured from 1990 to unknown. Jarufo (July 13, 2009): Tube complement, each monoblock: 2 x 300B 1 x 12BH7 1 x 12AT7 The VTL Triode 45 is a monoblock amplifier , and uses a push-pull output stage with two 300B. The driver and phase inverter, is a 12BH7 tube and the input stage, uses a paralleled 12AT7WA. The input impedance is 135 Kohms. This monoblock, gives about 23 watts rms into an 8 ohms load. 12AT7 的柵極輸入電阻改用 1K ohm, 300B 的柵極輸入電阻也是改用 1K ohm, 300B 的陰極對地電阻改用 100 ohm 碳精兩兩並聯, 並且修改陰極對地電阻的位置,
