“A very lovely ARP Axxe in fantastic cosmetic condition!
**No output from the VCO, on either of the waveforms**
The Noise output can be heard, as can the filter, which self-oscillates mightily with the resonance up, these little things are beastly!
You can process external sounds through the filter, and modulate that from the LFO.
Doesn’t seem to be triggering from the keyboard (I used the slider directly, as well as a Keystep via CV/ Gate) and not sure the ADSR is working correctly either, the Release seems to act as VCA gain level, rather than fading out accordingly. The last time I looked at this, I recall it was 100% aside from the lack of signal from the VCO, so may be missing something. The Key Repeat slider seems ok too.
A pretty simple circuit, schematics and parts easily available, doesn’t look to have been messed with in any way. It is possible to plug the connector cables in backwards on this ARP gear, but pretty sure it’s all in the right place. If the sliders flake out, they can also cut the audio, but not really suspecting those either. Straightforward, if time-consuming to dismantle and clean those if needed, and I actually have a few spares if it does turn out to be a dodgy fader.
100% original, some missing screws in some of the pics to show the innards, but they’re all included. May *possibly* have some caps knocking around too.. they’re notoriously brittle with age and often split into pieces, and the sliders look and function just fine without them.
*have found most of the sliders, see last pic, including one broken, glued & broken again.. should really clamp these while gluing if poss*” Click here to visit listing on eBay
