[Premium-Rx] Chase Measuring Receivers

[spencer bahner]

Greetings Premium RX-ers-

 

Does anyone know anything about the specialized measuring and EMI/EMC receivers made by Chase in the UK? 

 

More specifically, I have a Chase 4431 portable receiver and would love to find an operators manual and service manual for it. I can't seem to find any details on Chase, especially as concerns their still being in business. Can anyone fill me in on if Chase has been bought by a company that might still have manuals available or if they know of a source who can supply manual copies?

 

Thanks!
