Caution: This page is only valid for transformers that contain these exact color codes for the primary winding. Early

production units did not contain a multiple tap transformer. If the terminal strip has all these color coded wires, then the

unit has the multiple tap transformer.

FILAMENT/BLOWER WIRING INSTRUCTIONS

The AL-82 and 82(X) amplifiers come prewired for 240V line voltage and with the blower prewired for medium high

fan speed. NOTE: The AL-82J Japanese export model is prewired for 208V line voltage and with the blower prewired

for medium high fan speed.. This page gives filament transformer connection details for various line voltages and

blower speeds. The five lug terminal strip and the single lug terminal strip are located immediately behind the ON/OFF

rocker switch inside the unit. The drawing below shows the connection of transformer leads and their purpose.

This chart shows the color code of the transformer leads and their purpose. The number in paren-

thesis indicates the number of the terminal

number three (3) lug is not used to change the filament or blower wiring. Do not add or remove

any wires from the number three (3) lug. Refer to the drawing above. Use the lug numbers above

when referring to both of the Filament connection chart and the Blower connection chart below.

FILAMENT TRANSFORMER LINE VOLTAGE There

are two wires that connect to the terminal lugs which

determine the Filament Line Voltage. The BLACK wire

from the power switch and WHITE wire from rear of the

unit connect to different terminal lugs depending on the

voltage desired. The AL-82 and 82(X) come prewired for

240V operation`. AL-82J comes prewired for 200V

operation". Refer to the chart below. The voltage listed in

the chart below is the maximum line voltage that should be

applied to a given tap. Operation with line voltage in

excess of the tap voltage selected can result in a reduction

of tube life.

BLOWER CONNECTIONS

The GREEN and WHITE wires from the rear of the unit

connect to the terminal lugs to control the air speed of the

fan. The AL-82/X/J are prewired for the medium high speed

setting'. Refer to the chart below. The blower connections

can be moved to lower speed taps if air noise is excessive.

Ameritron recommends using the highest speed tap that

noise considerations permit. The lowest speed tap will

develop sufficient air flow for standard amateur SSB and

CW full power operation. The highest speed taps should be

used for contest or RTTY operation.
