Emax

hi!

Can anyone here recommend a place to get replacement DAC chips for the
Emax. I have mine in service now thinking I had to replace the
PSU..they told me they suspect its the 8 DAC chips that are bad.
(AM6012PC)

 have a suspicion these will be hard to find....

thanks,

michael

It appears that those chips are still made by Phillips, although they
don't have a PC postfix, just D and F.  I suspect they would work
fine, although I'd like to at least compare pinouts.  However, losing
8 chips seems suspicious.  

I found this: http://store.americanmicrosemiconductor.com/am6012pc.html
You can't afford 8 of them though.  I'm wondering if it has an
equivalent that was more mainstream and also if it's available surplus.

I agree.....
8 DAC chips bad ?
Is there somewhere else you could take it for a second
opinion ?

True- I've heard of losing chips but it does make me wonder how 8 have been
damaged. I had taken it to a place that regularly services synth for me..but
they thought it was a dead power supply and original parts were unavailable.
They were wary to use anything 3rd party to fix it.  This 2nd guy claims the
PSU is okay- but traced problems to the DAC converters.
I did find another chip that is said to be a replacement for the AM6012-
found it from a store supplying arcade game parts.(at about $5 each) I'll
see how these new chips work out.

Cheers,

michael

You mean Emax -- not Emax II, right?

>  have a suspicion these will be hard to find....

For Emax II, this mail would contain the needed information:
http://launch.groups.yahoo.com/group/emax/message/1834

For the original Emax, I don't know -- sorry. 

But the principle of how the DACs work is probably exactly the same,
just less bits.
