Thorhauge I 270 integrated amplifier
Hand made hard wired EL34 push pull integrated amplifier in fixed bias with 70w per channel!
Thorhauge I 270 2x70W push pull integrated amplifier in excellent condition.
This 70w Integrated amplifier comes with remote control for volume.
The amplifier is very musical and is a rare beast as it is a fixed bias unit as opposed to the more usual cathode bias type of amplifier. Fixed bias provides a tighter bass response and ensures all valves are running at their optimum. Bias adjustment is easily done by adjusting a single trimmer to 5.5 volts which is common to all tubes. The adjustment will be made from above the top plate using the supplied multimeter.
The amplifier is coupled ultralinear.
The inlet tube is JJ ECC 81 and driver tubes are Electro Harmonix 12BH/7
The eight EL34 output tubes is from EH or JJ.
The power supply consists of a transformer at 500W and a battery of capacitors in 3,000 uf. which is substantial in a tube amp. This ensures a powerful reproduction with immense headroom.
It is suited for speakers of 4 or 8 ohm. Being a powerful unit means it can drive less efficient speaker systems with ease.
This amplifier is in excellent condition and represents fantastic value.
This is a large and heavy amplifier. Buyers can collect from Dundee or Doncaster, failing which we will happily deliver for an greed delivery cost.
