4、e May 15, 00 Indications: Amplifier cuts out after a few minutes of high volume use. Part Numbers affected: 30-51-6063 (output amp heat sink) and 12-30-3886 (output device) Tools/Supplies Required: #2 Phillips screwdriver, heat sink compound Repair Procedure Remove the (4) chassis screws on the top

5、of the amplifier. ! Remove the (2) handle screws. ! Disconnect the speaker leads, remarking the location the leads ! Remove the (2) screws on the bottom of the chassis ! Remove the nuts on the 1/4 phone and the effects send and return jacks ! Slowly pull the bottom plate of the chassis off and when

6、it pulls away, reach in and pull the ribbon connector from the main board. ! Look at the amplifier IC and see if the screw holding the output IC to the heat sink is in straight. If it is you can loosen the screws on the bottom of the heat sink and tighten the screw to 10-12 in lbs. If the screw is n

7、ot straight, you may need to replace the heat sink. Also be sure that there is sufficient heat sink compound on the back of the IC. It should cover the back but not ooze out when the IC is secured tightly. ! Reassemble the unit Warranty Implications: This is considered a warranty issue. Production S

Agoura Hills, CA 91301 Tel. 818-575-3600 Fax 818-676-1585 Bulletin 05: POD Pro Date codes affected: Units Produced Before 6-15-00 Indications: Intermittent power with vibration of the unit. Pa

16、rt Numbers affected Fuse holder; old part number 21-48-9521, change to 21-48-2071 (two per unit) Tools/Supplies Required: #2 Phillips head screwdriver, controlled output soldering station, 4mm Allen wrench, needle nose pliers Repair Procedure: There are two possible solutions for this problem. We ha

17、ve found that pinching the fuse holder to get a better connection has been very effective. The other possibility is to change the fuse holder. This should be done if it is not possible to get a good connection by pinching the fuse holder. You can test the effectiveness of pinching the fuse holder by

18、 vibrating the unit fervently and observing the lights on the front panel to see if they flicker with vibration. The procedure to replace the fuse holder is detailed below. The first steps are the disassembly instructions to access the fuse holder inside the unit. ! To remove the top cover, remove t

19、he (6) #2 Phillips head screws on the top cover. ! To remove the side panel, remove the (2) screws on the back panel, remove the (2) screws on the bottom panel and remove the (2) 4mm Allen head screws on the from panel. ! You can now access the fuse holder. From the solder side of the PCB, apply the

20、 soldering iron to one of the fuse holders and wait for the solder to liquefy. ! With the needle nose pliers, pull the fuse holder out from the component side of the board and repeat the procedure with the second fuse holder. ! You may need to use solder wick or a solder sucker to remove the excess

21、solder from the hole before installing the new fuse holder. ! You will have to cut off one of the legs of the new fuse holder to accommodate the footprint of the PCB ! Once the orientation of the fuse holder is correct, you can solder the new fuse holder in place ! Reassemble the unit and test by vi

22、brating the unit. If there is no fluctuation in the front panel lights, the repair has been successful.

24、3600 Fax 818-676-1585 Bulletin 006: Spider 112 / 210 Mainboard Revisions affected: Rev 0 through Rev. 5.0 Indications : AC receptacle wired directly to mainboard. (No AC board). Part Numbers affected: 50-00-0080 and 50-00-0082 Repair Procedure : Older versions of Spider 112 and 210 do not have separ

25、ate AC daughterboards. The AC receptacle was connected directly to the mainboard. Newer versions have an AC daughterboard attached to the AC receptacle which connects to the transformer and power switch. Because of this, the newer main boards have fewer tabs than the older boards. If you have an old

26、er Spider 112 or 210 that does not have an AC daughterboard on the AC receptacle and you need to order a new mainboard (50-00- 0080), you must also order the AC daughterboard (50-00-0082). Production Status : All production models are now manufactured using the AC daughterboard. ECO # 9929401 Custom

Part Numbers affected : 11-10-0601 (L3-L13) Tools/Supplies Required: Soldering iron / DVM Repair Procedure : Check appropriate

30、 inductor (see above) with DVM for continuity and replace if open. If problem is intermittent, it may be necessary to flex PCB slightly for inductor to become open. Make sure standoff insulation pads are in place when PCB is re-installed. Warranty Implications: These failures are considered in-warra

35、h and/or volume pedal not working Part Numbers affected 09-00-4401 Tools/Supplies Required Soldering Iron, Phillips head Screw Driver Repair Procedure Sometimes the wah and/or volume pedal on the floorboard will not work due to failure of a photo transistor (ref. M2, M3), Photo LED (M5, M6) or a tra

36、nsistor (Q1, Q2). Also, a damaged, smeared, creased or torn optical strip may be the problem but more often than not, the cause is Q1 or Q2 being pushed through the PCB causing the solder connections to break. This can happen when pressure is applied to the top of the floorboard by a players foot an

37、d the top plate pushes down on the transistors enough to break the connections to the PCB. The solution is to reheat the solder points on the respective transistor, push the transistor so that it sits no higher than 7.5 millimeters above the PCB surface and then re-solder it into place. It is import

38、ant to check the condition of the transistor before re-soldering it. Check for creased, dented or split legs or any other signs of potential transistor failure before proceeding with this adjustment. Warranty Implications This should be considered a warranty repair (domestically only). Production St

39、atus All production models are assembled with Q1 and Q2 no higher than 7.5mm. Customer Service Tel: 818-575-3600 Customer Service Fax: 818-676-1585 Line 6 Inc. 29901 Agoura Rd.
