Hi Guys
I bought this an year and half ago and not used due to work pressure. Working fine and the Shibasoku name is well known for their extreme low distortion oscillator! The item is in Austin expecting 550$ plus shipping and paypal fee or US postal money order. I am willing to ship overseas but only by USPS priority mail with insurance /tracking
let me know

Thanks for responding to my inquiry on eBay. I just can't justify owning another distortion analyzer. Could you post a picture of the bottom view with the cover off? That is where they must have the distortion filters.

I suspect that this could be capable of some pretty impressive performance with a little help. Shibasoku is really bad about manuals but enough has been found to figure out most of their products and the internal trimmers are marked in English.
 
Bottom cover open - photos showing Osc and distortion range selection sections
Anybody wants complete pictures ( DIYAUDIO ) site does not accept bigger photos- so PM me with email I can send

That looks really well built. The two transformers on the left in #3 are the input/output transformers. I can't really tell from these pictures but it looks like it has a two stage fixed tune notch filter (no autonull). It also looks to be a good candidate for hotrodding with the newer lower distortion opamps.
