TRIODE CORPN. Of JAPAN 845/300B "SIGNATURE" MONOBLOCK PAIR

These went to a very pleasant customer in Indonesia in 2002, page is for reference only!!

This is a Pair of Direct-Heated Triode Tube Amps that use a combination of the 845 and 300B Tubes;

OUTPUT: 28W per Monoblock into 8 Ohms
SPECIFICATIONS: (per Monoblock):
MITCAP Coupling Condensors, Toroidal Transformers, Plate voltages: 300B 410V, 845: 950V.
There is a 30 second "warmup" relay to preserve Tube life
Internal windings, and wiring, use quality 6N Copper
Tube complement: 6SL7, 6SN7,(made in USA) 300B, 845 (made in China)
Input Impedance: 100k Ohms Output Taps; 4 Ohm, 8 Ohm
Drawn current: 150W per Monoblock. Weight: 33kg (66kg pair, about 140 pounds)
Size: W285mm x L470mm x H210mm (approx. W11.5 ins x L18.5 ins x 8.5 ins) x 2

Frequency response: 15Hz-30kHz (+- 1dB), Measured distortion: less than 0.1% a 1kHz
S/N: better than 90dB

Currently set to operate at: 100V 50/60Hz,
NOTE: conversion to 120V (USA voltage) can be done at the Japan-side service centre; this takes 7-10 days and costs US$100 ( both Amps) if required this will be done at cost.
　

What the Specification can't tell you is these sound Superb; you could "tube roll" some RCA 845's and some other Brand 300B's but the Setup is outstanding just as it is.
This Product was voted "Best Buy of the Year" by Japan's Stereo Sound magazine in 2001
Units are ex-DEMO's; I would describe the condition conservatively as 9.0 out of 10.0, no scratches, no problems.

These have a Biasing adjustment, and Biasing Gauge, (adjusts the 845) and I found in practice, they can be "tuned" to suit the system they're in. Overall very high quality Triode Tube Amps, without the usual constraint of needing high efficiency Speakers. Truly a High End product in every respect
