I'm repairing a 1938/39 Golden Knight model CKU which appears to have originally been a reasonably high end all-wave 6-volt vibrator powered set - with push pull 6G6G's in the output driving an early Rola PM speaker.
Things I've noted so far:
- one of the 6G6's has been smashed
- the RF valve lead on to the cap has been cut completely off and is missing
- the tuning drive is slipping
- the volume control 'display' cord has snapped
- one of the power supply caps has blown completely apart
- the tone control has come loose in the chassis and has twisted itself into oblivion
- The hot wire from the incoming power cord is just twisted around the on-off switch terminal and had started to come untwisted and was about ready to touch metal
- 1938ish radio with an EZ81 rectifier!
The second-to-last point is a timely reminder to never assume you can plug one of these sets in without checking underneath first... At first glance this radio looks fantastic and I almost fell into the trap of assuming the insides would match the outsides, and fitting a new 6G6G then powering it up - which could have been fun - it seems like someone with cabinet skills may have restored it cosmetically and then just left the chassis. I'm hoping the owner might be able to elaborate on that.
And the last point about the EZ81 seems fine, and you might assume a repairman bunged that in some time in the late 50's once AC mains was more prevalent - until you look at how its fitted - the socket looks like it was riveted in at the factory - and the wiring is factory-neat and tidy as well... it's almost like it went back to Radio Ltd 20 years after it was made for a conversion to 230V mains... which is not something I've seen before. Did they do that?
All in all, it's an interesting set... I doubt I'll ever know its history, but its certainly one that has made me wonder...
