REPAIR SERVICE        REPAIR SERVICE
Please note:  This is a Repair Service for your existing malfunctioning amp plate.  You send us your malfunctioning amp plate and we repair it and send it back to you.  It is not the outright purchase of a new or used replacement amp plate.  You will receive back the same amp plate that you send us, only repaired and updated and functioning as new.  Please read this description in its entirety before purchasing.

This a flat rate repair service for the JBL S120Pii powered subwoofer amplifier plate.  This is a great subwoofer, but sooner or later the subwoofer plate fails.  ElectroNetix has repaired many of them, and will get yours working quickly. Simply do a "Buy It Now" and once we receive your payment, we will respond by sending you detailed removal and shipping instructions and an address to ship your malfunctioning amp plate (in Chicago area).  We will repair it, update it, correct several design flaws that may have led to its failure, test it to factory specs, and ship it back to you, with turn around of 5 business days or less (exclusive of shipping).  With shipping time included, you should have it back in less than 10 days. Our service comes with a 60 day warranty.

Our charge is flat rate and includes all parts and labor to repair normal electrical failure with one exception.  If the two large power supply filter capacitors need replacing, or if you simply want them replaced as a preventative measure even though they may not be bad, there is an extra charge of $25 which basically covers the cost of the parts.  Failure of the power supply filter capacitors on this unit is not a frequent occurrence, and we do not recommend changing them unless they are bulging on top.  We end up replacing the power supply filter capacitors on less than 10% of the units that are sent to us for repair.

One of the primary failure modes of this amp can sometimes cause significant burning of the main circuit board.  Small burn areas can be repaired, but very large burn areas on the main circuit board may render the unit non-repairable.  Before sending us the unit you will need to check for this, and we will advise you how to do it, and send us photos if necessary.

Note that you will pay for shipping the amp plate to us (about $15-25 depending on carrier and distance).  The shipping charge that you pay as part of this purchase is for return shipping back to you.  You ship only the amp plate, not the entire subwoofer. We will provide you with instructions on how to remove the amp plate and the best methods for shipment.  This repair service at the advertised cost is for continental US customers only.  We will gladly service other customers, but please request a quote due to the higher cost of return shipping.

IMPORTANT NOTE ON PACKING AND SHIPPING:  You must either ship the amp with the black plastic box enclosure with the amp plate securely screwed into the plastic box, or ship it with the wood frame shown in the four photos.  The wood frame can be made from 1"x4" plain board and consists of 2 pieces 8" long and 2 pieces 12 1/2" long.  You will also need ten 1 5/8" drywall screws.  You can buy the board for a couple dollars at Home Depot and they will even cut it to these lengths for free.  DO NOT SHIP THE AMP PLATE BY ITSELF WITHOUT EITHER THE PLASTIC BOX OR THE WOOD FRAME AS THERE IS A HIGH LIKELIHOOD IT WILL BE SEVERELY DAMAGED!

If you have any questions, please send us a message before you purchase, and we will get back to you quickly.

If you happen to reside in the Chicago area (Dupage County) and want to drop off and pickup, send us a message and we arrange for that and you can save money on shipping.

This Repair Service is for the JBL S120Pii sub amp plate only.  We also repair other subwoofer amp plates, so if you have a different model visit our store, or send us a message with the brand and model number, and a brief description of the symptoms,  and we will give you an estimate on the repair.
