FUSE:

This is the A.C.’s ( 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 2 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 some day.

WARNING:

Unplug power before replacing fuse or removing bolts mounting chassis.

RECORD / PHONES:

This jack provides direct-to-console interfacing for recording or sound reinforcement applications. It can also be used to power a set of personal headphones which is a convenient way to practice day or night privately. It is a circuit dedicated to reproducing the roll off that occurs in the output section with a speaker connected.

The send level strength is determined by the GAIN and MASTER controls. From this jack, adequate signal level will be available to you for most of your recording needs and live direct performances.

		FX LOOP: SEND & RETURN
		These two 1/4" jacks are the patch point for external effects. The Effects Loop is
	FX MIX	wired in parallel with the normal signal. Connect the SEND jack of the F-Seriesto
10%		your Effects Input jack. Connect the RETURN jack of the F-Seriesto the Output jack
	100 %
	RETURN	of your effect unit. The Effects Loop is a patch point between the pre-amp and power
		section. Therefore, the RETURN jack can double as a “Power Amp Input” jack.

When the RETURN is used as an input, the F-SeriesFX MIX control is the only of the mode selected and should be set to 100%. While the RETURN is being used in this manner,
