Thank you to everyone who gave feedback about the PEM issue.
I visited the warehouse and checked the kits on shelf, and determined that a little less than half the remaining WHAMMY kits have PEM DD12.1121.111 ("One Amp, Screw A, 2 pole fuseholder, 2 pole line switch") instead of DD12.4111.111 ("4 Amp, Screw A, 1 pole fuseholder, 2 pole line switch").
After consulting our supplier, it turns out Digikey sent a number of 1121s in the order of 4111s.
The most practical solution to remedy the issue is to obtain one Schurter 4301.1413 "Fingergrip, 2 pole fuseholder, shorting bar on neutral side" (
Digikey /
Mouser). Any customer who has received a kit containing a PEM labelled DD12.1121.111 is welcome to either obtain said part themselves and contact the helpdesk for a refund of the part value, or contact the helpdesk and we will arrange for the 4301.1413 fuseholder to be shipped out to you at no cost to you.
All kits containing PEM DD12.1121.111 have been identified and set aside at the warehouse and will be updated with the 4301.1413 fuseholder. All customers who purchased a WHAMMY from this batch will be contacted and asked to check they have the correct PEM and if not we will ship a replacement fuseholder.
Thank you for your understanding.
