SCA Amp Kit Build Service

Some of the best amplifiers in the world come as kits. The Elekit TU-8900, the TU-8888 monoblock pair, the TU-8400 — these are serious, high-performance designs that happen to arrive unassembled. If building is not your preference, Secret Chord Analogue will build one for you.

What's included

The build service covers the complete assembly of your chosen kit: component installation, soldering, wiring, and full electrical testing before the amplifier leaves the workshop. Eutectic solder is used throughout — a higher-quality alloy than standard solder that eliminates cold joints and flux residue. Every build is tested for correct operation before dispatch.

The amplifier arrives ready to connect and play. No further assembly required.

How to order

Add the kit to your cart and add the matching build service variant. Both items ship together once the build is complete. Build lead time is typically two to four weeks from receipt of the kit — contact us to confirm current availability before ordering.

Note: postage is not included in the build service fee and is invoiced separately.

Prefer a supervised build?

If you'd like to build the amplifier yourself with expert guidance, Amp Camp in Wentworth Falls is the alternative — a one-day supervised workshop where you do the build and leave with a working amplifier.
