Optocouplers are still in wide use in the FX world. The Vactrol VTL
series seems the most popular these days so people also roll they're own
with an LED or bulb and an LDR.
BBDs are still in production in China. Clones of the Panasonic MN32xx
series are available. Smallbear Electronics is a popular DIY FX pedal
supplier that carries them.

As you increased delay, the noise level also increased very noticeably. They are not made any more. Which, even with their weaknesses, is a shame.]
