- But what you fail to mention here is that any bad signal or spike that you may
- feed into this circuit will completely blow up your Ensoniq chip. Unless
- you've got "connections" and can order one directly from the company, you're
- looking at a motherboard swap to fix this. Oops.
-
- What you get for your $50: a cheap REPLACEABLE op-amp that will happily die
- in place of the Ensoniq when you decide to feed it a really nasty signal.
-
- One more thing that you should at least do if you haven't listened to me, is
- to add a capacitor in series with the signal input so that you can get rid of
- DC offsets. This is what killed mine when I did the exact same thing a few
- years back. Take my advice, it's REALLY not fun trying to get ahold of a new
- Ensoniq chip.
