pace-Tech Laboratory HP-150 DLX is a tube solid state hybrid amplifier. As the photos depict, it is in very good condition. The amp is working well with all tubes testing good.  At 150Wrms / channel single-ended tube hybrid power amplifier, it combines both the advantage of a transistor amp's high current drive (tight bass and good speaker control) and single-ended vacuum tube amplification (warm and sweet sound with good depth, sound stage, and air). The transistor output stage is a voltage to current converter circuit without any NFB or voltage gain, so the non-linear sound of transistors can be greatly eliminated. Left behind is the high damping factor that controls the speaker more efficiently. The tube section is working in an optimized single-ended operation mode to achieve the purest and most natural tonal quality. If you were unaware of this amplifier construction, and you judged the sound quality by listening only, you would believe it was a pure tube power amplifier and not a hybrid. Specifications: - # of inputs: 1 set of RCA inputs ; 1 set of balanced inputs - # of outputs: 1 set of speaker outputs - Freq response: 1Hz - 150Khz (-3db) - S/N better than 95 db - Gain x15-x25 depending on tubes - Phase 180deg inverted - manufacturing hand-wired point to point for tube section - dual volume controls Tubes that can be used: - 2x 6SL7/6SN7(this is installed)/6SU7/ECC32/ECC33/ECC35/6188 - 2x 6L6G/EL34/5881/6K6/6V6/KT66/6550/KT88(this is installed)/KT100) - 1x 5U4G/5AR4/5V4G/274B(this is installed) tube rectifier This amplifier has a visual appeal to those that love tubes, want to see/hear them at play with power. NOTE: PRICE IN US DOLLARS.
