V-TYPE V8 TEST PROCEDURE
ISSUE A PS 2/3/2000 Initial Checks 1) 2) 3) Check the polarity of all electrolytic capacitors and diodes on power board. Install all fuses and valves (see accompanying sheet). Set all rotary controls to midway position, all push switches out. (front and rear) Set to FULL POWER and turn both BIAS ADJUST pots fully clockwise. Set rear panel mains switch to OFF and front panel toggle to STANDBY. Connect unit to (4) load station. Connect mains socket to variac set at minimum. Switch unit to standby mode. Gradually turn up the variac to the appropriate voltage. Green lamp and front and green mains switch will light up.

4)

Voltage Tests 5) Check following Test Points (TP):(all DC TP's are w.r.t. TP0 0V) 6.3vac ±0.6vac 24V ±1V 12V ±0.5V -60V ±3V -60V ±3V

TP1/TP2 TP3 TP4 TP5 TP6 6) 7)

Turn variac to minimum. Switch from STANDBY to ON, return variac to correct voltage. Set bias as follows:Insert black DMM probe (-) into 0V hole, red (+) into V1 on rear panel. Slowly turn left hand ADJUST control to give a reading of 0.300V ±0.03V. Insert black probe into V2, carefully rotate the right hand ADJUST to give 0mV ±0.01V. Repeat above procedure as appropriate until settings are correct. (The setting of the two ADJUST pots interact) Check biasing of other valves, if necessary adjust bias again to bring all valves within the 0.270 0.330V range. V1 - TP15 V2 - TP16 V3 - TP17 V4 - TP18 V5 - TP19 V6 - TP20 V7 - TP21 V8 - TP22

Sine wave tests 10) Insert 1Khz, -20dBu (77mVrms) sine wave into the PASSIVE INPUT. Turn up GAIN I fully then adjust MASTER until the output starts to clip. Check the power is >400W (40vrms @ 4 ) and the EM84 display valve is fully lit. Using screwdriver handle gently tap each valve and check for microphony and instability. Switch to HALF POWER mode. (on rear panel) Check there is a reduction in output power (~25vrms @ 4 ). Return to FULL POWER. Turn GAIN I back to half way. Insert sig. gen. lead into ACTIVE INPUT and then back into PASSIVE. Check that when in ACTIVE the output level approximately halves. Press BRIGHT, signal should increase slightly. Pull out GAIN II. Check signal on scope is as shown:Adjust GAIN II & LEVEL controls to check smooth operation. Return to half way. Push DEEP. Signal should increase slightly. Push out again. Turn TREBLE, MIDDLE & BASS to minimum. Turn BASS to maximum, check signal on scope:Return to minimum. Turn MIDDLE to maximum, check signal on scope:Return to minimum. Turn TREBLE to maximum, check signal on scope:Return controls back to half way. Push in GAIN II. Signal should be clean again. Switch on COMPRESSOR, signal should increase slighlty. Turn up LEVEL, the blue LED should be lit just before full. Turn off COMPRESSOR, blue LED should fade out.

Rear Panel 20) 21) 22) Check that none of the rear LED's are lit. Using a screwdriver remove each fuse, one at a time. Check each LED lights up. Check correct functionality of 2 way foot switch socket. Tip should switch from GAIN I to GAIN II, ring switches COMPRESSOR on/off. Check there is an output at the correct level from the following sockets:DI OUT (POST/GROUND) DI OUT (PRE/GROUND) LINE OUT SEND 23) ~20mV p/p ~350mV p/p ~1.2V p/p ~200mV p/p

Turn MASTER control to minimum and switch unit to STANDBY. Connect output to appropriate speaker cabinet and bass guitar Aurally test main features of each channel and check for any excessive hum or noise. Connect to load & sig. gen., set up for full power and soak test for approx. 30 minutes. End of test. 2
