- I got this from the net a while ago, and tried it out on my A1000.
- (I went for the switch option, and mount it on the front panel
- beside DF0). It worked fine for me, but usual disclaimers etc. apply.

- Disabling the filters on the A1000
- ----------------------------------
- To disable the audio filter on an Amiga 1000 snip one leg of capacitors
- C103 & C104. These capacitors should be right next to each other. If
- you are more ambitious you could hook up a DPST switch to switch the
- filter capacitors in and out. Make sure you use shielded cable that has
- two internal conductors for each capacitor. The shielding should be
- hooked up to ground. BTW, the capacitors are located beneath the
- "daughter board" so you'll have to remove it first to access the
- two little beasties. If for some reason this doesn't work for your
- 1000 version than all you'll need to do is put a tad of solder on the
- snipped leg and all will be back to normal.
