I have an old Boss analog delay. It doesnt work anymore. I thought that bread boards and circuits last forever?...well at least 30 or 40 years.

many of those old delay units used a SAD-1024 chip. the chips were dirt cheap for a while. now they aren't in production any more. that's likely what's wrong with yours. but if the chip is still OK, it's probably worth more than the price of repairs to the BOSS. they're usually on a socket, so if you are throwing the unit out, keep the chip. if you have another working device that uses the same chip, and that chip works, you'll have a spare.

Blue, (i hope that's okay, or do you prefer Deepblue?) thanks for the compliment, but in general, there are others on this board that are far more knowledgable about guitars. however, when it comes to the electronics side of things, i can mostly keep up with ChrisK and JohnH. it seems like everyone here has something to offer. it's become apparent that you're our official Beatles historian, IMHO a very important position. although we can't pay you either! unk |

...they're usually on a socket, so if you are throwing the unit out, keep the chip. Don't throw it out! That could turn into a really cool project. Poke around the internet and you'll find someone who has disected that pedal and can show you how to bring it back to life. I haven't the time to check for prices on replacement chips, but it seems there might be a suitable alternative somewhere out there. And if you don't want to try it give it to someone who does (like me). Hey I ought to start a rescue group for dead pedals, just like they have for old greyhounds. |

i've got a friend who needs a 4096. there was one he could have bought, but no way was he going to pay $100 for a chip that originally cost $5, and put it in a unit that would then be worth about $50. |

Hey Unk,
Give me a day or 2 I might have one in my junk box!
Hopefully I didn't toss it during one of the past cleanups.

Thanks Ron,
if you do happen to have a 4096, drop me a P.M. and we'll work out the details.
if you don't, thanks for thinkin' about me.

Try www.digikey.com I find they have a crapload of odd parts. The catalogue is a blast from the past! (Like the old Radio Shack catalogues when I was a wee one.) |

Sorry Unk,
After an exhaustive search, I came up empty. Sad thing is I never realized how many "junk" boxes I have.

Ron,
i do appreciate the effort. it was thoughtful of you to spend the time for me on that quest.
amazing, isn't it, how looking through those old junk-boxes brings back nearly forgotten memories?
Mlrpa,
as expected, no joy at digi-key.
i have had many occasions to do business with them. low prices, lots of common stuff, occasional odd-bits. great for the young experimenters out there. in the same style as jameco and poly-paks (back-in-the-day).
Thanks guys,
unk
