Most common faults:
1. Constant buzzing noise (click to hear) – that’s probably the most common of all faults and is caused by an overheating following design flaw, which means sooner or later this will happen to each amplifier of these series. Your unit can not just be repaired, but as well modified in a way to rectify the design issues and to prevent the same problem reoccur. The cost of this repair starts from £35* including required components.
2. Sudden loud pop/thump coming from the speaker – common fault, again, caused by a design flaw, which will be rectified during the repair to prevent further repeat issues. The cost of repair starts from £45* and includes all required components.
3. There is power, but no sound produced. This could be caused by several component failures, and sometimes could be a bit expensive to repair. I will provide personal advise in that case. The cost for this repair starts from £40* and exact quote will be given after diagnostic.
4. Cuts-out at high volume level, but works fine at low levels – usually when you turn up the volume, you can hear a relay click and sound cuts-out until you turn the volume down again. This is caused by ageing component and the cost of the repair starts at £35*.
5. There’s no power at all, the mains fuse blows when replaced, or is OK, but no signs of power going to the unit (no green or red light). Again, this could be caused by several components failure and most times would be a bit more expensive to repair. Advice will be provided in such case, depending on the specific fault. The cost for this repair starts from £40* and exact quote will be given after diagnostic.
6. Low volume high-pitched whining noise – caused by components failure due to overheating. Repair starts at £40* and is included as preventative upgrade with all upgrade inclusive repairs.
7. Low rumbling noise – common for few revisions of the pre-amplifier on older units. Repair starts at £40* and is included as preventative upgrade with all upgrade inclusive repairs on affected amplifiers.
Payment & Repairs
You’re welcome to pay by PayPal or bank transfer – but don’t worry, you won’t be charged a penny until your repair has been successfully completed. Once everything’s sorted, I’ll get in touch with the payment details.
If, after the diagnostic, you decide not to go ahead with the repair, that’s completely fine – the diagnostic is free, and you’ll only need to cover the return postage.
Optional Upgrades & Advice
Depending on how old your unit is and which revision of the board it has, there may be certain upgrades I’d recommend – even if your amplifier isn’t showing any issues just yet. These upgrades are based on known issues that can develop over time.
Wherever possible, I’ll offer a few repair or upgrade options so you can choose what suits you best. That said, I’ll always give honest advice if I think an upgrade is worthwhile – I’d much rather help you avoid a bigger, costlier repair down the line than save a few pounds today.
Sending in Your Unit
Repairs are done in-house, so you’ll need to send your amplifier in. For full details on how to do that, please click here.
