Battery replacement service:

Memory backup fitted to the Kairn, Claissik, Wakonda, and Numerik fails over time and needs to be replaced. Unfortunately, many of the original units leak and cause corrosion to the printed circuit board. It’s best to act swiftly if you find your battery unreliable, as corrosion can become significant, causing irreparable damage to the printed circuit board.

What’s included:

  • Safe removal of the original battery
  • Replacement with a modern equivalent
  • Cleaning of any leakage damage
  • Repair of minor PCB damage (if present)

Result:
✔ Reliable memory retention

✔ Fixes Error 2 messages

SKU: N/A Category:

Once repairs and upgrades have been completed, the PSU equipment will be tested and calibrated to the recommended output voltages. All work will be carried out by an experienced Chartered Electrical and Electronic Engineer. Once you have ordered, details will be emailed to you on how to send the repair to us. The equipment will be shipped back to you via recorded delivery/courier.

Try to ship your equipment to or within the UK using a medium parcel size. Ideally, less than 46 x 46 x 61 cm. We recommend shipping the entire unit, rather than just the SMPS, so we can verify overall operation.

Q: You are showing out of stock, how do I order?
We open limited weekly slots for these repairs to keep turnaround times quick. We control the slots with stock availability. Please keep checking back.

Q: Is this a known issue with older Linn units?
Yes – Brilliant power supplies and backup batteries are known wear components.

Q: Will this improve sound quality?
It restores correct operation and stability, improving overall performance and can improve sound quality if the PSU was noisy.

Q: Do you offer a warranty?
Yes – all repairs include a 6-month warranty on replaced components and associated labour.

Q: What is turnaround time?
Typically, 14–21 working days from the time we receive the equipment (can be longer in severe-damage cases).
