Well the two admiral radios arrived today!
I took apart the 5AW and gave the chassis a clean and inspected everything but unfortunately the original 3 ohm speaker has moisture damage and rubs quite bad so I need to find a replacement for that.
As long as the I.F. Cans don’t have silver migration in the caps it should be very easy to get going.
I think I’m going to make a new case out of sheet metal for the 5AW and keep the 5ACW in its original case.
Either way it will be great to get them going. Taking a closer inspection of the 5AW someone used some sort of green heat shrink to hold the dial light in place but that had long since gone open. Mind you still the original set of AWV valves unless they were all replaced at the same time with a complete set of AWV but seems unlikely. I’ll definitely be checking the 6AQ5 for emission and the couplate for leakage and resistor values.

Hi, scroll back to the 18th Jun 2016 in special projects, I played about with a couple of 5ACW and tarted both of them up.
Interesting sets.

Thanks Fred
I took a look and read the PDF you made.
I can definitely see what you mean by a rushed design!
Interesting to note that the clock version is earthed while the 5AW is not.
You also noted that the same chassis was used in a AWA radio which makes sense as to why my radio has a complete compliment of AWV valves.
My 5ACW is missing the random power socket on the back. What was it’s purpose?
I checked the resistors in the couplate and they are all up in value like the two 470k are up over 610k, one of which is intermittent so I’m going to just rebuild the couplate with modern parts and never worry about it again.

Hi I think that socket on the back was supposed to be an outlet switched by the alarm, maybe for a light?
Probably did not make much sense so they blocked the hole with a fitting and left it at that.
Hers a joke thought.
Maybe if you are quick enough, when the alarm goes off, you unplug the set from the mains and plug that into the back socket wired from the alarm.
Then the set continues to play running from the power from the out let.
What could possibly go wrong?
Perpetual motion!!!!!!
Sorry.
Fred.

I think the idea was that the radio would turn on and also fire up the kettle you'd thoughtfully filled with water the night before.
Being in the kitchen you had enough time to get up and make a pot of tea (or coffee of course)
Anyway it'd probably be the kettle's whistle that woke you!

Love it! Would however, hope that if the kettle idea was put into practice, that the switches & wiring could handle it and that I doubt.
Amusing but! .

I have a 1950s Tea Maid, actually I have 2 of them ! Kids were always amazed when I would set it before bed and in the mornings the bell would ring to get up and there it had made the Tea ! Kids just loved it and when people use to visit it our house they would always say , wow can you show me how it works ? Sure want to stay the night ha hahaha
I'm coffee drinker ,but boy it was popular.

Well good progress has been made and now the Admiral 5AW is electrically restored and works wonderfully!
First I reflowed every solder joint, replaced the power cord with a earthed one, replaced the electrolytics and manufactured my own couplate.
I also went ahead and replaced the wrecked speaker with one from jaycar and over all the radio has great sound and sensitivity.
