Headphone Amplifier Frigate
This page has moved to this URL
Frigate is a high end pure class A OTL DIY tube headphone amplifier kit designed for the highest quality music reproduction with the minimum distortion. An essential part of any good sounding headphones is the amplifier that is driving them. Frigate is capable of driving a wide range of headphones from 30 Ohm Grado to 300 Ohm Schennheiser and it will give you the best advantage in listening pleasure. The most immediately noticeable quality of Frigate is its silent background, nearly totally devoid of hiss. With the volume turned to maximum listening levels and no music playing, there is dead silence. With matched Electro Harmonix 6922 and Sovtek 6H30Pi driver tubes, the amplifier puts out a rock and roll flavor, with that midrange and lower-treble hardness that makes rock enjoyable. The impact of percussive instruments is forceful, and it feels like air is being moved on deeper bass notes. The bass extends quite deep and is somewhat emphasized in a slightly round way. The best way to describe Frigate's sound is to say it is ORGANIC.
Do not compare this tube amplifier with the ones made somewhere in Asia from counterfeit parts and using low voltage Wal-Mart switching power supplies. Frigate uses only the finest audiophile quality components that have been carefully selected with no expense spared. Frigate uses two 6922 and two 6H30Pi tubes for their linearity and low distortion. The 6922 and 6H30Pi tubes are matched with an aid of Amplitrex tube tester and a computer. High quality Kemet, WIMA, Nichicon capacitors are used along with an audio grade ALPS volume potentiometer. Military grade Vishay/Dale metal film resistors used throughout the kit. A high quality triple bus power supply Trident (situated on a separate PCB) with ultra low noise characteristics delivers anode and filament voltages and a very generous amount of post and pre regulation smoothing capacitance provided by Nichicon and Kemet capacitors. The kit is assembled on Canadian made printed circuit boards that have thickness of 1.75 millimeters and 2 Oz copper traces. You have a choice of purchasing a transformless amplifier kit or a kit that includes filament 182L12 and B+ 182E110 transformers. The transformers are manufactured in Waterloo, Canada and are designed for both 120V and 240V power arrangements.
Headphone tube amplifier kit Frigate was originally designed to be housed on a same PCB with its three bus power supply Trident. Following suggestions of our customers, we redesigned the kit and the power supply Trident and the amplifier Frigate now have their individual PCBs.
Headphone amplifier Frigate is shipped the same business day it is purchased via Canada Post Express with a tracking number.
