I have fixed a Derwent radio-No Model Number.  Valve/tube line-up ECH35-EF39-EBC33-EL33-U50. I have done research on this radio and learned it is similar to Raymond F17 Information may be of help to fellow enthusiast.My Derwent is now working .Replaced the Main Electrolytics( filter)- both were dead.
