This Apprentice Zone will soon be populated by information/hints/tips/ but mainly responses to queries and requests made by you, the Apprentice! I hope that this will be the foundation of a long and useful relationship where we can share expertise and learn together. I’m especially looking forward to the discourse I will be having with those of you from The States and the Far East where the radios can be very different to that which can be found in the UK!

Corona Virus!      Friday June 5th 2020


 

Thanks for your understanding!


The Corona Virus is finally passing its Peak here in the UK. We have been supporting our daughter and son as best we can given that they are trying to juggle three under 4 yr old youngsters (daughter 2, son 1) and try and work… Both are self employed so you know the score in terms of help via government etc.. Don't get me started on the way in which here in the UK the pandemic has been dealt with. Suffice to say I’m looking forward to using my vote to get the present bunch of buffoons out of office in due course.



What an awful experience it has been and continues to be and, touch wood, I haven’t been infected.  I am working on a couple of videos which with a fair wind and a bit of luck should be on here soon but in the mean time I will be sending each of you (at long last!) the first in a series of Lesson Plans/Information Packs electronically so you can get started.  (I may call them something else but its the ‘old teacher’ in me!) These will arrive in the next few days.


I’ll also be pointing you to some of the best You Tube videos to look at. There are a great many on You Tube concerned with restoring and repairing vintage radios and some of them are fantastic but the majority are unsafe and pretty bad! Beware!


I’m planning to have the first … Best wishes all!!

Here’s a problem… Have a think and let me and the rest of the group put forward a few ideas on how this one could be fixed? What’s the problem? What can you see in the photos that might be a cause for concern??

Someone has asked me to take a look at a Steepletone radio/CD player that they have that holds great sentimental value for them. It was being used and then “just stopped working”. I’ve discovered a slow blow 2A fuse inside. This had failed and there is evidence of heating on the corner of the circuit board that is fed by the current after the fuse. I replaced the fuse and, unsurprisingly, it blew too. Would you have any idea what is causing the problem and is it an easy fix?

This capacitor has obviously been changed in the past.. Its a 0.001uf high voltage type (the 102 on the side points to its value)

Done some more checks and discovered that one of the diodes that firm the rectifier has had it! Other three show forward voltage of 0.55V and it shows basically nothing.

This is the capacitor:


As you said, mains-rated; it is across one of the diodes. The other capacitor is 20 nF and it’s across the diode that has failed.

My comments will be in these blue coloured boxes.. Yours in the green!
