Components - list



Details of the components are given below. See the Where to buy and Component Pin-outs pages for more information.

Fuses


There are three fuses inside the subwoofer. They are Wickmann fuses (may now be called Littelfuse or Littelfuse Wickmann as Littelfuse has taken over Wickmann) and are soldered to the PCB.

If replacing any of the fuses, they must be replaced by a fuse of the same type and rating:


Relay PCB

F650:

T3.15A /250v  type 382 fuse    

Littelfuse part number: 38213150410       

Farnell order code: 171-6667

RS stock no. 377-2180



Amplifier PCB

F400 and F401:

T5A / 250v type 382 fuse        

Littelfuse part number: 38215000410     

Farnell order code: 171-6673

RS stock no. 377-2203


The last four digits of the Littelfuse part number (0410) simple refers to the packaging. These can be supplied individually with stockists referring to the code as 0410 or 0430 (the end zero may be omitted). The actual fuse is exactly the same, whatever the code is.


Note - shop around for stockists of these fuses. Farnell currently charge a £15.95 delivery charge for importing them from the USA!  RS components sell these in packs of 10 and currently charge £4.95 delivery.



Replacement LEDs


The SMD LEDs are made by Avago. I assume that the wallwasher LEDs are also made by them.


I have tried various LEDs for suitability as a replacement. This includes all the Avago LEDs that I can find in the same colour range. I have not replaced the LED on a PCB to test it, instead I have compared the existing PCB LED with the LED I’ve been testing by using the LED diode tester test - see the Sidelight page Testing LEDs for a description.


The test was carried out using two identical diode testers at the same time - one connected to the PCB LED for the colour that was being compared, the other connected to the LED under test. The light from both LEDs was then compared. Because of the way the test was done, it was not possible to display either LED at full brightness, however both LEDs had the same current so the test was equal between the LED on the PCB and the LED under test.


It may be difficult to get an exacting matching replacement LED. Not all LEDs are the same and vary according to brightness, colour shade and view angle (the spread of the light - some LEDs give out light in a straight, almost pin-point beam, in others the light is more evenly spread). You need to match all three when getting a replacement. The LEDs used in the lights have a fairly wide beam range, which means that the light is distributed over a wider area.



The results below will give you an idea of the nearest LED you could use. There may be other LEDs available, from the same or a different maker that are suitable. If the LED isn’t an exact match, most of the time it will not matter. The only time it will be noticeable is when two lights are together (as in the wallwasher) or two sidelights are together and the colour and brightness of the lights is steady. It may be possible to make up any slight change in colour or brightness by calibrating the light, but personally I wouldn’t bother. Calibrating can be a lot of fiddling around and there’s no guarantee that what you end up with is any improvement and you may make it worse. Look up detailed information on each LED on the data sheets that are available from the supplier or from the manufacturers web site.


I have given the mcd of the LED as listed on the supplier’s page, but there does seem to be some discrepancy in the way that the figure is given, so these details might not be of much use. I have also given the view angle when listed.


There are two types of LEDS. The ones in the sidelights are Surface Mounted Devices which solder direct to the surface of the PCB. The ones in the wallwasher are the more standard “through hole” type of fixing where they have leads that go through holes on the PCB. They are then soldered and the excess leads removed.


Details of the LEDs that were tested are given below. Sometimes it was hard to distinguish whether the test LED was any brighter or not. Those with little or no difference would probably be suitable to use as a replacement.


REMEMBER - just because several LEDs are not working, doesn’t mean that they are all faulty! - see the Sidelights pages Sidelights Faults and Testing LEDs.


If you have used a LED that is not listed here and it has been an exact replacement, please let me know. Give details of the supplier, their order number and the maker and their part number if known.

Wallwasher lights


The wallwasher LEDs are 5mm oval and are tinted diffused (they are transparent with the colour tint, rather than the more solid colour as often seen in round LEDs). Although round 5mm LEDs may fit on the PCB (the pin spacing is the same), the oval LEDs give a much better viewing angle. Replace the LEDs with the oval type if possible. The DEG is the view angle - 100 DEG is wide, 8 DEG is narrow. The oval LEDs below are generally more “cloudier” looking than the original (not quite as transparent), but it doesn’t seem to make any difference.


Wallwasher LEDs under test - all LEDs are oval unless stated

GREEN

all the green LEDs have a slightly yellower look to them compared to the original, whereas the original has a slightly bluer look when compared to these LEDs. probably not enough to make that much difference if one LED is replaced, but may affect the colour slightly if a group of green LEDs are replaced.
