I know its a Rodotron from pictures on there site, the control board is similar to the Wei Ya - with the 75 - 100ohm switch, but the numbr 666 on the right gave it away that it was a Rodotron Tri Sync chassis
Rodotron list it as a CH-666-29
Pentranic list as a CH666, the tube is an FST but the chassis match.
when I say its on a coldcircuit, I mean it does a quick degauss on power up, but will only deguss again when the monitor has been switched off and left off for about 20 minutes or so
