The kit, and just the kit, fits into a padded envelope, and that costs the least to mail (important since the price includes postage). The chassis boxes weigh more, and they will push the shipping price up. International mail is much more, and is driven by weight and parcel dimensions.

If you must have package tracking and a non-US address, it will cost a great deal more. All international destinations (including Canada) ship via USPS only. The rest are far too complicated for ordinary humans (us).

USPS now has tracking by default for domestic mail.

Washington State residents must pay retail sales tax, which is based on the delivery address.

For a price, we can supply completely assembled preamps, made to your order. This usually takes about 4-weeks. See the price list for more details.

(1). The kit components are largely RoHS compliant, but since the kit is considered a repair part, it is exempt from RoHS rules.

(2) Customers in countries outside of the USA are responsible for any and all applicable taxes, duties, VAT, fees, and RoHS issues. The de minimus exemption for low-value parcels is gone, and the EU seems to have reciprocated. The charge seems to be about 50-euros in Europe, but we have not been able to find a succinct chart telling what each member state charges.
(3) Washington State customers must pay applicable sales tax (amount depends on your delivery address).
