[sdiy] *Legacy* chips available now (saving for the future?)

[Greg James]

Pete,

 

This was basically what I was thinking in my OP. I have a small inventory of some of the original era parts that are now re-issued. If I’m fixing a vintage circuit, I’d like to use the vintage part. Sometimes the form factor or voltages have changed and putting a new vintage part requires retro-fitting, which doesn’t help.

 

But basically it sounds like folks think I’m a wacko (trust me, there are many others that think so too), so I’ll just treat this thread as closed.

 

Greg

Maintenance is exactly it.

 

If my guitar or violin or what have you has some kind of problem, a good luthier and some quality wood are essentially all you need.  Neither is going away any time soon.

Whereas I can't just take some silicon and conjure up a missing chip.  Obviously *some* folks can, Or we couldn't have Alfa or SSI or XVive, but it's far beyond the means and ability of most of us who repair synths.

 

I think one of the issues here is that people want to treat their instruments *like instruments*, whereas the creators of many of them (at the corporate level, no disrespect to any of the electronics wizards who've made these things possible) really were creating "products" instead.  You can see serviceability designed into some of the older gear, but once the digital revolution took hold in the 80's it's increasingly difficult, and I don't think any of them have had the idea of instruments lasting for decades or longer (possibly due to other reasons than simply not caring, but the effect is the same).

Pete

But why storing random "soon to be deprecated" components
other than for maintenance and finishing an ongoing production?
I do not get it...
