Agree 100%. Anything new built with discontinued
parts limits product life and uses up spares.
Why not just build a Moog ladder filter? It's
in the right family and uses discrete parts.
Might become a new classic.

And maybe they'll stop people buying up broken
Siel synths and ripping out the filter chips.
Pure vandalism.
