Warranty and Refunds

· Standard warranty on our assembled items (excluding assembled PCB's) is 2 years. The warranty follows the product and is transferrable.

· WE CANNOT ISSUE REFUNDS on custom builds once completed. We can offer limited mods and tweaks (excluding those under policy update 4-29-2020 below) within 30 days of receipt.

· Deposits for custom builds are non-refundable after 10 calendar days of your receipt of the work order (in person or via distance contract) for us to assemble the unit. Please know what you want us to build for you before you leave a deposit and we order parts.

Note on Custom Builds

· We do NOT build items from schematics purchased or found on the web or in books unless it's specifically marked open-source - that is copyright violation and intellectual property theft. We are a business and the build will be for commercial use [we would build it to sell to you for labour and parts]. Another major reason we do not do this is because the item is not of our research and development design, we can't guarantee performance or reliability.

• If you want special parts (wire, controls, switches, resistors, capacitors, anything, etc.) you must tell us BEFORE the unit is built. If you decide to send us parts AFTER the unit is built, there will be a $100/hr. ($100 minimum, $500 maximum) Swap-Out fee.

• We are also disallowing user modifications and upgrades. Opening the case beyond what is allowed in the user manual will VOID the warranty and/or make the units non-returnable under any circumstances.
Certain technicians do have our conifidence, please contact if we know someone in your area.

• We test each product before releasing it to you. In order to make sure of the utmost quality, we will not release a product until it has passed rigorous testing. This can take up to to weeks after completion. Please do not ask us to release it earlier.


· Shipping is via Canada Post. Where value needs declaring, the full value is used. We do not fudge values and requesting us to do so is grounds for us to refund your purchase and refuse sales/service to you.

· You will receive an estimated time to ship for custom builds. Lead time can be up to 100 days during busy times for our custom transformer supplier.

· Shipping quotes are estimated with Canada Post's online calculator.

· You pay Canada Post exact + what we pay for packing. We do not pad our shipping for profit!

· Due to RoHS and electrical certification differences, our finished amps and preamps can't be shipped to any EU country.

· Note that shipping damage is NOT covered under Canada Post insurance or our warranty!

· Local pickup is OK. You will be contacted when your order is ready for pickup.
