Is the BC204 a BC206 in a smaller package? Well, not quite but it's awfully close
as far as music reproduction goes. If your system doesn't need the extra wattage
and you'd like an amplifier that you can pick up without calling the neighbours for
help then the BC204 might be the one
-output..150watts into 8 ohms and 250 watts into 4 ohms per channel.
-True balanced from input to output with both positive and negative binding posts
being "hot" with signal.
-DC coupled output stage.
-local "on board" filtering capacitors located less than an inch away from the actual
output devices for better transient response.
-all control circuits are done in the analog domain. Therefore, no digital clock
to contaminate the analog signal integrity. It s an analog amp after all.
-heavy gauge power supply ground return path for both tube and output stages with
the exact same reference for both tube and output stages, to yield the best matching
-20Amp Neutrik "Power Con" power connector for optimum connectivity of ac power.
BC61 (14 AWG ) power cord with Hubbell plug. The standard length is 4 ft. Longer
lengths are available to suit specific customer requirements.
-All internal ac power is controlled by 30A ac power relays for shortest ac power
run inside the chassis.
-850VA power transformer supply for output stage only.
-three separate power transformers for output stage, tube input stage and controls
-over 240,000uF in power supply filtering.
-power HexFred rectifier in both output stage and B+ supply.
-12Ga steel chassis for mechanical integrity.
-1" thick MDF base tightly coupled to the bottom of the chassis for ultra rigid damping
-Various colours of faceplate, base and cover as options.
-Two pairs of binding post per channel for shot gun biwire.
-RCA and XLR inputs.
-Ground lift switch to eliminate ground loops. This switch will only lift the signal
ground, the chassis is connected to earth ground at all times for safety.
-Dimensions: 17.5" wide x 9.875" high x 21.5" deep.
