Manley Labs STUDIO STANDARD 350 WATT MONOBLOCK AMPLIFIER instruction

BIAS PROCEDURES

The Manley Studio Standard 350 is a fixed bias system that requires very little attention. If you wish to adjust or check the bias, follow the following steps.

1.On diagram 1, which depicts the front panel of the Manley 350, you can see two measurement tip jacks labled "READ BIAS". Place the probes of a standard volt meter in these sockets and set the volt meter to read 'millivolts'.

2.Directly below these tip jacks is a knob labeled with sixteen points. Since the Manley Studio Standard 350 only has 8 output tubes, only half of these sixteen positions can be obtained. The switch when set at 1 o'clock will read output tube ones's voltage drop across the cathode resistor. Simularly, as you continue clockwise you will continue until you reach tube eight's bias voltage.

3.On diagram 2, which depicts the top view of the Manley 350, you will see the tube numbering sequence and the bias adjust pots used to alter the bias of each tube.

4.The first step to setting the bias is to turn on the amplifier and ensure that there is zero signal input. Also, leave your loadspeakers connected as these provide an ideal load on the output. It is recommended that tha you leave the amplifier on long enough to ensure that the tubes have reached their stable current draw.

5.Set the switch to the one o'clock position and adjust the first trim pot (furthest left) until you measure 300 to 350 mV. Since you are measuring across a 10 ohm cathode resistor, this would correspond to 30 to 35 mA of bias current.

6.If you are unable to bring the bias down to 30 to 35 mA on any tube then we recommend that the tube be carefully watched or replaced.

7.Follow step five with the remaining tubes. Once they are all set, your amplifier should be in perfectoperation.

NOTE: There are two red tip jacks and one pot on the top of the amplifier which should not be altered. These tip jacks are used to measure the AC balance which is factory set and should never need adjustment.
