just a rebrand. tektronix, tenma , metrix,  made in china somewhere .. long ago

these things are old. they are plagued by two problems :
1) the keypads become sticky / intermittent. you need to take the front off , clean the pcb with alcohol and apply a fresh coat of carbon on the membrane
2) the output on/off is done by clunky relays. no softstart. these relays eventually go bad.

another annoyance of these supplies is that there is no rotary dial. so if you need to play with a varying supply it becomes tedious ...

i got a stack of those in the lab where i work. nobody wants to touch em anymore. they all got problematic keypads / bad relays and have fried many a board during poweron  ( oh and you cannot control individual output on. it's all or nothing )
