The delay pedals that still use them are generally way more expensive, because they require NOS chips. I seem to recall someone doing a re-tape of one of the old bucket-brigade delays, but don't know if that ever actually happened.

Bucket brigade chips are currently being made. Here's one for 5 pounds:

Why would you introduce such complexity for small lengths of recording when DRAM is so cheap?

Smack an FPGA in it and implement a turbo encoder. Easy  :-DD
