Tokyo Sound 100SE - Service information hunt

[FPALB]

Hello!
Just got a call from a new customer who is looking to have a Tokyo Sound 100SE serviced. I can't much of anything on this amplifier or the manufacturer - sure is a pretty looking single ended unit. Anybody have any experience with these?

hi, (sorry) I have no idea where you can obtain any servicing info. I thought they (Tokyo Sound owned the Guyatone brand) went out of business (checking my memory against the wiki, apparently they continued, setting up shop in the U.S.) :

Looks like some Hi-Fi amp?

This blog has a schemo for a Valve 300SE (upmarket model?) showing a schematic. Perhaps there are similarities?
