Farm radio

Post by Ben Delk on Mon Apr 10, 2017 9:20 pm

i have friend who's grandfather past. He had a sentinel 118bt-216-s. That's a mouth full. She has a sentimental attachment to it and asked if it could be restored. I replied' anything can be restored for a price. I've  never had a battery radio so my question is what are the obstacles? She would like it to be convertered to 110 volt system.
Should I run from this or is there a process for this and what else would need to be changed?

Ben, link the schematic so we can see what you need. I have done a couple simple 90V/1.5V supplies in a faux battery. Looks great and you don't have to modify the radio in any way.

Ben, here is a link to the powersuppy I have built a few of. Works great and I covered the "box" with battery graphics.

And a link showing your powersupply in a nice package resembling a battery with an A/C line coming out.

Looks great. Do you have a larger picture of the schematic. When you enlarge the one listed it gets where you cant read it. PM you on this ?

There is a good article on making them over at Phils old radios. I made the one at the bottom called a/b/c or something similar. I built a couple of them and they seem like a decent little unit. I think its similar to one of the previous posts.

Best,  Jerry

Yup, the battery sets work really well in most cases and a power supply such as Jerry has suggested is a fun and straightforward build.

Alternately, if you wanted to keep it more original (not necessary, but sometimes nice to do), there were factory built battery eliminators available and they are not too expensive and they are easily restored. The model "Silvertone Powr Shiftr" comes to mind, and yes, the spelling is correct.

cheers

Ben, if you can't get it bigger, just go to google and search for farm radio power supplies.  This one will pop up more often than anything.  A classic.  The parts are nothing, the perf board and box were the most expensive.

I have a sillvertone power shifter. The rectifiers are built into the case. I had replaced open filters, but, rectifiers have flown south.
