Assembly hints
1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a
small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to
the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.
• Thin raisin-core solder. Do not use any flux or grease. • A diagonal cutter to trim excess wires. To avoid injury when cutting
excess leads, hold the lead so they cannot fly towards the eyes. • Needle nose pliers, for bending leads, or to hold compo-
nents in place. • Small blade and phillips screwdrivers. A basic range
is fine.
For some projects, a basic multi-meter is required, or might
be handy 1.2 Assembly Hints : ⇒ Make sure the skill level matches your experience, to avoid disappointments. ⇒ Follow the instructions carefully. Read and understand the entire step before
you perform each operation. ⇒ Perform the assembly in the correct order as stated in this manual ⇒ Position all parts on the PCB (Printed Circuit Board) as shown on the draw-
ings. ⇒ Values on the circuit diagram are subject to changes. ⇒ Values in this assembly guide are correct*
0.000

⇒ Use the check-boxes to mark your progress. ⇒ Please read the included information on safety and customer service * Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet. 1.3 Soldering Hints :
1- Mount the component against the PCB sur-face and carefully solder the leads
2- Make sure the solder joints are cone-shaped and shiny
3- Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE ONE AT A
TIME !

The unit consists out of two PCB’s, one is the main PCB, P8020B and the other is the left channel input section P8021L. First we will start with the small P8021L, then we assemble the P8021B.
FTip: The pictures on the packaging can be used as a guideline. However, due to possible changes it is not 100% reliable.

q Cut the thread in the front and
back of the aluminum profiles, using the supplied special M4 screw (4 holes per piece)
q Mount the feet on the aluminum pro-
file, using four M4 hexagonal Allen screws. Use the supplied Allen wrench. It is advisable to stick the pro-tection adhesive onto the feet.
q Mount the valve pro-
tection covers on one of the aluminum pro-files. Use four M4 hex-agonal Allen screws.

knife or a screwdriver to scratch the paint from the alu-minum fixation, from the hole closest to the back end. This fixation will be used later to connect the ground and earth.
q Mount the 3, 5mm
(0.14”) spacers like in the drawing. Using three hexagonal screws and a washer. Do not tighten the spacers yet.
q Position the PCB in the enclosure and check if the position of the spacers is
correct, if so, remove the PCB and tighten the spacers. q Using an ohmmeter, measure between the edge of the aluminum profile and
the back spacer, if there is a good electric contact (0 ohm). If not, repeat the above step to remove the paint under the spacer.

q Check if the potentiometer turns smoothly without touching the front panel, other-wise correct his position or the position of the front panel.
F Use the supplied Allen wrench q Remove the front panel and fix the nuts of the potentiometer bracket. q Remove the PCB from the enclosure and solder the potentiometer connec-
tions.
IMPORTANT: q Slide an M3 hexagonal screw into the profile
side. Position the screw about in the center of the profile.
q Again mount the pcb into the enclosure. q Fix the pcb using a 2cm (0.8”)
spacer at the position next to SK07 and use 5mm spacers to fix the other two positions. Measure, using an ohm meter (or continuity beeper) if the 2cm spacer is electrically con-nected to the ground wire (yellow green wire). If not, re-check if the paint of the alumi-num is correctly removed.
q Mount the left channel PCB onto
the spacers, check that the con-nector is correctly inserted. Fix the PCB using five 6mm M3 screws.

q Mount the front panel onto the
front, using two M4 Allen screws.
FCheck the position of the LED’s and check if all buttons are working correctly. It could be that paint rest over in the holes, is preventing the buttons from smooth opera-tion.

Connect the power cord to the mains connector. Connect the power cord to the mains output
CAUTION: Some points on the PCB are connected to the danger-ous mains voltage or high DC voltage.
Push the power button (or one of the input selection buttons) Check if the power supply LED LD08 is lit. This means that the high voltage is correct. Normally the valves filaments (or heaters) must also work. Disconnect the mains plug. Check the user manual to test all functions and operation of the unit, then the aluminum cover can be mounted. Please note that the user manual is also used for the ready assembled version. Some remarks may not be related to the kit version.
