Allwave 15 Serial #L-448

[Kelly McDaniel]

Brought my father's Scott radio from US to Canada hope of getting it working again after many years of it sitting on a shelf. I may be Allwave 15 but I'm sure someone can confirm or correct this. Serial #L-448. If there is someone in Alberta that can test/troubleshoot the operational side I would like to pursue this first. The unit has no case but I should be able to fashion a period cabinet here, it may have been a Tasman style cabinet intended for the components? I travel to and from Calgary/Denver often, may be able to transport this to the US along that path or divert if necessary. I want to restore the unit to operational order and build the cabinet and eventually return this to my family in Colorado.

Any guidance would be greatly appreciated.

I would suggest having an experienced technician look at this radio and go thru it before powering it on.  You can do a lot of damage otherwise.

I concur whole heartedly. My dilemma is how to find the experienced technician within some reasonable distance to my home (Calgary, Canada). I also typically travel to Denver a number of times throughout the year so can make arrangements to move the components anyway along that route or some place that deviates within reason. I have reached out to our local Ham radio club in Calgary (CARA) but have not received any replies. I am trying to reach a guy here near Edmonton from this group but am still waiting on his reply to see if he has the expertise. Any other suggestions of alternate techs that might take this on? I of course am willing to pay for their time and any materials as well. VA6MC VA6CPN VE0CPN

took the base plate off of the receiver today to see if there is any obvious evidence of replaced electronic components, everything looks original to this neophyte.

No - the pair of 2A3 tubes are amplifier tubes.            

The 5Z3 is the rectifier tube, part of the high voltage circuit - this tube produces pulsating direct current, the first step in turning household alternating current into steady high voltage direct current needed for the amplifier tubes and tubes in the receiver.  The 3 cylindrical filter capacitors need to be in good condition and probably be replaced.

Hi Kelly,

Yes, I could have a look at it, and access what will be needed. 

Best to call or text me.

Not sure if my former reply went through correctly. If I were to schlep the radio/power supply and speaker components to you near Edmonton would you be able to test and advise? My knowledge of electronics is very low to say the least but I am always willing to learn.

Welcome!

The speaker will definitely need to be re-coned to sound it's best. It may be possible to patch up the cone using coffee filters, but the damage looks pretty severe.

I am three hours north of Calgary, near Edmonton if I can be of help.

The set looks very original, nice condition. I hope you and Brad can make connections, he would be a great resource to help with your set.
