ALPS RK271-series volume pot (10 kΩ, audio taper; Mouser P/N: 688-RK27112AS-103)

I ordered the Alps pot from RS Components to Hamilton Canada.
The pot plus delivery came to $30.37 USD
The duty came to $20.06 CAD

Mouser wouldn't have the pot in stock till April. I ordered from RS Components so I could get the 20mm version. I'm pleased I don't have to take a hack saw to the pot but I didn't expect the duty.

Either way I'd though I'd give the head's up to any Canadian builders thinking of ordering that part...

I was hoping it would be that easy, thanks Tom

Just connect Pin 1 to Pin 3 on the XLR connectors. Take the RCA shell to the Pin 1/3 and the RCA centre pin to Pin 2 of the XLR connector footprint. Then simply use the on-board input selector switch.

I sure didn‘t. Sorry if it came across that way, I was taking for granted that this was a cardinal sin never to be committed and surprised you even felt the need to mention it. I now see how one could read that post differently. Mea culpa

I ordered 50 of those from RS recently. Paid CAD $11 to DHL for the customs processing and $48.39 CAD in GST (5% as I'm in Alberta). Seems pretty reasonable on a $1k+ order...

You can double-check the paperwork from DHL, but it's probably the processing fee that bit you.
One way to avoid the processing fee is to use FedEx and set up an account with them. You can have the customs fees charged to your account and the shipping fees to the vendor's account (they likely get a much better deal than you do). That eliminates the $10 brokerage fee that FedEx charges. FedEx does tend to be more expensive than DHL, though.

Alps must be really backed up in their production. I ordered 500 custom RK271 pots (through a distributor) in September and have yet to receive any word on when they'll ship. They quoted 2-3 months lead time at the time.

I dunno. If I start selling them, should I be licensed as a pot dispensary? That would be a fantastic question to ask the local authorities on such matters on April 1.
