General Precaution

• To prevent short circuit during any test, the oscilloscope must be EARTH insulated,

this occurs because some test require to connect its probe to the ampliﬁer output, non-com-

pliance may cause damages to oscilloscope inputs circuitry.

• Before removing or installing any modules and connectors, disconnect the ampliﬁer from

AC MAINS and measure the DC supply voltages across each of the power suppliy capacitors.

If your measurement on any of the caps is greater than 10Vdc, connect a 100Ω 10W resi-

stor across the applicable caps to discharge them for your safety. Remember to remove the

discharge resistor immediately after discharging caps. Do not power up the ampliﬁer with

the discharge resistor connected.

• Read these notes entirely before proceeding to any operation. These notes are not com-

prehensive of all damages that possibly occur, but includes some speciﬁcally advices, checks

and adjustments relative to this ampliﬁed speaker.

• Do not check the ampliﬁer with the speaker connected use only an appropriate load

resistor.

• BE CAREFUL increasing the Variac you must not exceed the nominal mains voltage plus

its tolerance (see speciﬁcations) any upper voltage can be cause of damage.

Visual Check

• Check the speakers for any damaging (cone-breaking, interruption or so).

• Before proceed to supply the ampliﬁer check visually the internal assembly, if appears

an evident damage ﬁnd the most possible reasons that cause it.

• Check the wiring cables for possible interruptions or shorts.

• If the damage has burnt a printed circuit board don’t try to repair it, replace with a new

one.

Test Instruments

• Audio Generator

• Dual Trace Oscilloscope

• Digital Multimeter

• Temperature Meter

• 8Ω500W, 4Ω500W, 100Ω10W resistors

• Variac (0÷250Vac)

and one negative high rail (+/-Vcc2). The second ampliﬁer is supplied by means the onlylow

rail (+/-Vcc1).

lectors. Also see Advices section.

• Verify, with the Multimeter, the PTC resistor value (TH1), it must be between 50Ωand

200Ω.

F4-F5=62±1.5Vac.

• Re-set the Variac at zero voltage, turn off the ampliﬁer and put the fuses back on its

holders.

• Set up the Variac slowly monitoring the Outputs with the oscilloscope CH1 and CH2

connected, starts from 2/3 of nominal mains voltage it should display the sinusoidal input

signal ampliﬁed with no distortions, if a distortion occur or the protection trips check the

AMPLIFIER board as suggested in the ADVICES section.

• Finally verify the DC supplies on SUPPLY board:

CN1 pin 2 (+Vcc2) =+60±2Vdc

CN2 pin 3 (+Vcc1) =+43±1.5Vdc

CN2 pin 1 (-Vcc1) =-43±1.5Vdc

sts.
