DRIVER TUBES: 3 x 12AX7A to grab hold of the particular pre-amp tube when replacement is required. Do not allow your fingers, hands or rings/jewelry to come into contact with any other part (s) of the amplifier’s internal circuitry.

No other user serviceable parts exist in side. Refer service to qualified personnel. Always unplug AC power before removing the top cover of the amplifier.

AC RECEPTACLE: The total power consumption for the 2:100 is 6Amps @ 120 Volts. Thus, a 15 Amp circuit (which is what

most house circuitry is wired with) is adequate. Make sure the Euro style A.C. power cord is firmly seated in the power receptacle

 

 

 

before powering up the unit. Always connect the A.C. cord to a 3 terminal grounded socket. If none are available,

 

 

 

connect the A.C. power cord to a ground lift adaptor and then connect to a 2 terminal outlet. This may also be

 

 

 

 

 

 

necessary from time to time for noise problems.

 

 

 

This style of power cord will make tear-downs and cable routing a lot easier and save you time as well. If you

LINE FUSE: This is the 2:100’s A.C.Õs ( Alternating Current ) main fuse and provides protection from outside A.C. fluctuations, as well as power tube failure damage. Should the FUSE blow, replace it with the same rating in a slo-blo type package. The domestic U.S. version requires a 6 Amp SLO-BLO FUSE. A power tube short or failure is often the cause of a blown fuse...Follow the cold start procedure mentioned earlier in the ON / STANDBY switch section and watch the power tubes as you flip the STANDBY to the ON position. If a power tube is going bad or is arcing you will see it!

Flip the STANDBY switch to STANDBY immediately and replace the faulty power tube and the FUSE if necessary. If you see nothing abnormal as you lift the STANDBY switch, it is possible that a power tube shorted temporarily and blew the FUSE. If this is the case it may work again normally.

To be extra safe you may want to replace all power tubes in the troubleshooting tradition and save the replaced set as spares. Carry along a few extra fuses for they too could be worth their weight in gold someday.
