A quick perusal of the
Princeton Technologies website today revealed that the
PT2395 is no longer listed as a chip of theirs in their
Echo Processor section. Though this doesn't necessarily mean that they've totally stopped making them, it's still a potential bummer as the PT2395 is the core to many excellent pedals and DIY projects. You can still buy PT2395's in various places, including
smallbear. The necessary 41256 RAM chip has also long been extinct, so it looks like delays using the PT2395 are going to start fading out.
On the upside, the more popular PT2399 and less PT2396 are still available, with nicer, bigger datasheets.
