Hi from Jimb.
I have just taken delivery of another purchase AWA RADIOLA B42.
I have not powered it up yet. If anyone has a circuit diagram and any service information it would be greatly appreciated. Are there some common faults with these? I like early quality Australian 60's transistor radios they came out about the time I was about to start my apprenticeship and they were quite unaffordable on seven pounds and five shillings a week. I am looking forward to checking it out.
Regards Jimb.

You can download it yourself from here. Just click on the view of the schematic in the right hand pane then once it shows in the left hand pane double click there and follow the prompts:

I have a few of these too, I have a nice blue one which seems to be of better quality built than my others. The others I have are all black. The blue one is a very nice blue and it was my brothers when he was a boy and tossed it out years ago and I grabbed it!
Mine are the small awa radios
Its a b24 1962

Ah yes, that high impedance centre tapped speaker! Commonly went O/C on one leg, horrible distortion results. Remember them well.

Thank you GTC I have now downloaded the circiut.
Vintage Pete this is also a nice looking blue one but what a disaster!!
Hello Ian this share's some of your woes. Yes the speaker was open circuit the centre tap had broken off however I managed to repair it. This was a minor problem compared to the rest of it. The circiut board has a major crack in it.
It had been badly repaired in the past and there are also wires broken off the ferrite rod antenna. I desoldered some of the jumpers because the board had a 2mm gap in the split. I have managed to pull the gap closed but I need to repair the tracks, some I have repaired, it would be helpful if I can get a track side view of the pc board so I can check if I have repaired all the tracks. It does not look like it will be working any time soon.
Kind regards Jimb.

Help!!!
I am in a spot of bother. I have pieced the circuit board back together and fairly sure I have repaired all the tracks.I have two remaining problems two snapped off connections one is from the large section of the tuning gang the 10-200pf I am sure this connects onto the ferrite rod somewhere I do not know where, the blue wire from the gang looks like it snapped off out of the circuit board somewhere I cannot see where. It is more than likely I did this having the bad shakes things often get snapped off. The second is, I have a stray very fine wire on the ferrite rod not connected it seems to be associated with an over winding on the ferrite rod and no this does not connect to the tuning gang. I have tried with a meter to find the other end of this coil and I cannot locate it. I do now have a circuit diagram, but no overlay. I am not overly familiar with transistor radios I find them much more difficult to repair because of the Bakelite board that you can't see through. As I have stated I may have caused these faults due to my condition I was going to hang up my soldering iron, however I find that hard to do.
I have taken some photos but at this stage I do not want to bother Brad with uploading them.
The board now sits correctly on its mounting. It did not before due to the bad previous repair job.
Any help would welcome.
Kind regards Jimb.

The service details you were referred to on Radiomuseum is a single page schematic sourced from a J.R. handbook.

I'll send the full manufacturers service manual (7 pages) to Brad to upload here. It may be a bit more helpful.

Thank you Monochrome that will be a big help

Just thinking Monochrome my email is open it might be easier to send it that way to save Brad uploading.

Thank you Brad and Monochrome

Still in trouble. Again thank you Monochrome and Brad for your help the information is great. Apart from the broken off wire from the aerial coil across C1which is the 10-200pf tuning capacitor, it is actually open circuit. I have tried to wind another coil and it still does not work. I may not have given it enough turns it measures 1.4 ohms.
Is it important which rotation the coil is wound in relation to the other windings? How many ohms should this winding be? If I jumper the connection from c1 across another winding on the ferrite rod it tries to work it tunes in the very strong signal from my AM transmitter and it tunes through it, so the oscillator must be running and the audio end is ok. Any advice appreciated.
Regards Jimb.
What I am saying might be rubbish I am quite good at that. Looking at the circuit it tries to work if I connect the C1 tuning gang to the ferite rod connection point which feeds into the base of VT1 the oscillator transistor. The fact still remains that the tr1 winding is o/c.

Here I am again!!!
My wife cannot understand why I can't just throw this in the bin and sit in my chair with mouth open stairing at the ceiling, it is starting to look like a great alternative and it would be a great opportunity to reduce the fly population.
After ripping off another connection on the speaker from flexing the circuit board back and forth. I again fixed this and poured areldite all over the dining room table cloth this may have had some influence on my wife's remark, you just can't please all the people all the time.
I have done a rough repair on the ferrite rod and I still have a front end fault.
The I. F. end works fine, good sensitivity. I do not give up easily but likely to run out of table cloths at this rate so what can you do!!!!
The voltages around VT1 are incorrect the collector is ok 7.7V however the base is 0.45V it should be 1.1V. The emitter is 0.277 V. It should be 1.5V. I replaced C5 and C6 for no real reason except I was suspicious of these black polyester caps I had not seen before. I have now run out of ideas and I have positioned my self in my chair head pointing to the ceiling about to start fly catching.
Regards Jimb.

Jimb: I forget your background, but there's a well-trodden, systematic process for finding faults in radios. The alternative is shotgunning and that's both time wasting and frustrating.

A while back I listed some good books on the subject. The first two are especially recommended to those without a background in electronics:

Hi GTC.
MY background is electronics, industrial and broadcast television. However repairing frontend faults in transistor radios does not seem to be my my strong point. I find low signal frontend faults difficult. Keep in mind the circuit board was also badly cracked around this area. I do not usually shotgun things it was an act of sheer desperation.
