Description:
This pair of power monoblocks are designed with 300B tube to drive a pair of 845 vacuum tubes to produce beautiful midrange but with loads of power. It is designed to address audiophile's complaint that '300B amps are not powerful enough to drive those non-high efficiency speakers, but I still want the 300B sound'. The double power single ended 845 power will overcome those limitations, so that even with a pair of 84-89dB regular efficiency speakers, you can still enjoy the silky smooth sound of 300B with 845 tube's large sound stage.

Compared to the commonly seen Push-Pull 845 high power monoblocks design on other brands, which will more or less have crossover distortion as two tubes are used in push-pull design , the T845 uses Single Ended Triode paralelle circuit design - you benefit of superior single ended triode design without crossover distortion, plus double the power of regular SET amps. It provides 50w pure Class A power for each channel.

The King of all vacuum tubes - 845 tubes are used as output power tubes to deliver the beauty of 300B midrange sweetness, plus the punch and feel of spatial 3-D sound stage. You never feel the sound is 'thin' from this pair of power amps.

Features:
Separate transformers for high and low voltage - minimize noises caused by voltage interference inside the amp
German Permalloy used in all 12 hand wound transformers - 6 transformers for each channel
Pure Class A 50 watts SET Paralelle design - double the power compared to standard SET design (25w) with better control of low frequency, without losing the magic of SET circuitry
Little negative feedback used in circuit design
Very neat layout inside - super easy for changing caps or upgrade components if you wish (yes this will void manufacturers warranty but audiophiles sometimes are known for not being able to keep our hands off our equipment)
Stainless steel transformer cover to ensure quick heat dissipation
German 1/2" aluminum top plate with no screws visible on the top of the amp
Custom silver foil capacitors and Jensen silver signal wire inside
Custom Gold coated pure copper 845 tube sockets for long term best connection
Production process follow vintage Western Electric standards to ensure highest build quality
Custom 120V transformer for North American market - other voltage please special order
Easy manual bias on all four 845 tubes individually - you can monitor your tubes health closely and keep your amp in top notch performance all the time
Easy to move the amp around by lifting the edge of the 1/2" aluminum top plate (it's a 2-person job to move these amps - do not attempt by yourself! )
