ARP 4075 VCF on Japanese site

While checking for the Korg Delta VCF, I noticed Mr. Tanaka's latest addition to
 his DIY page, the ARP 4075 VCF.  It's the 4 pole filter that uses a 3900 for
its buffers.
What's interesting is that he used 2SA798s instead of tightly matched discrete
transistors.   Not that big of a deal, but it does simplify building one of
these filters.

PS, anybody know of an online translation engine (like Babelfish) that can
translate Japanese to English?
