aye, i bought it off the eevblog site, tried contacting him first, no reply.
i also tried basically all of the major european electronics sites i could think of, and of the few that replied, no-one seemed to have any stock of the part. eventually i managed to reach someone at brymen in taiwan who arranged for the spare to be included in a shipment of other stuff going to welectron, but they're ghosting me now and i don't really know what to do. i guess i'll keep trying to reach out to dave as well, but i suppose it's probably going to end up being a paperclip or tinfoil job for a while longer...
