OPERATIONAL NOTES
SWITCHINGON
The power switch is located on the lower left hand corner of the front panel. Push the top of the rocker switch (1) to turn on the amplifier and the bottom of the rocker to turn off the amplifier. The LED on the right side of the front panel will illuminate indicating that the amplifier is operating. Do not turn on and off the amplifier in rapid succession.
RUNNING
It is not recommended that you leave your amplifier permanently switched on. This only wastes electricity and tube life. Your amplifier has solid state rectification and reaches peak operating condition in approximately 30 minutes.
TUBELIFE
As with all tubes, their quality degrades with age. This is due to cathode emission, a natural process found in all tubes. We recommend that you have your amplifier checked every

Changing the light bulb:
The lamp which
The fuse lamp is 1 1/4" x 1/4" 8Volts, 300mA.
Fuses:
Always replace with same type and rating. Should the B+ fuse blow (the fuse nearer to the output binding posts) this usually indicates a tube has blown. One should visually inspect the pcb to look for any burnt resistors a blown tube may have taken out. Also a good test is to measure the resistance of each catode resistor. This is done in a similar fashion to checking the bias, except do this test with the amplifier turned OFF, and set your meter for Ohms. Each cathode resistor should measure 10 ohms.
