The dual-approach to development has led to the creation of a product that is different to anything Unison Research – or any other manufacturer – has developed before: a powerful, great-sounding amplifier with only three stages (two tube stages and one power MOSFET stage).

• Output power:     150+150 W on 8Ω / 250+250 W on 4Ω
• Valves: 2X ECC83 2X 6H30

• Input stage:     Pure A class, double triode totem pole ECC83
• Driver stage    Pure A class, double triode totem pole 6H30
• Input:    6 line (3 unbalanced, 2 balanced, 1 “bypass” unbalanced)
• Line Outputs:    1 tape, 1 sub  (volume controlled)
• Frequency response: -1dB @ 12Hz & 45kHz, -3 dB @ 6Hz & 80 kHz
• Input impedance:    24kΩ // 100pF
• Input sensitivity:    860mV RMS

We try and keep on top of our pricing, but it's a mammoth task for one person. So, if you see this product offered cheaper elsewhere, or you are offered it for less elsewhere (proof will be required) and you feel like supporting an extremely independent retailer, do get in touch and we will do our very best to match or beat wherever we can. We can't promise to do so, as there may some extenuating circumstances where we just wouldn't be able to, but we'll always do what we can.

Needs to be like for like - new for new, ex-demo for ex-demo, same colour and specs etc.
