Ia any filter in the Doepfer line-up able to stably self-oscillate at 
sub-audio frequencies?

hello jay,

i really don't know. the sub-audio-range is big,
which frequencies are you seeking, lower than 1 hz?

best wishes

Nothing like 1 cycle in 40 minutes, but at least a decent "normal" LFO 
range.

The A-108 has the most stable self oscillation level over a wide frequency
range. What is the lowest frequency you need? I will see if the A-108 is
self-oscillation at this frequency.

the a105 is maybe also worth a try.

1/10hz is probably the lowest I'd use.
