    I have a friend of that I am going to help with this radio.. It is a Sparton model 345-w or a 345-v.. it is a corner model and I would like to know where I can get the downloadable schematics for it .
    I believe that it is a Canadian model.. Any help would be appreciated Thanks Dan

    HI Dan – I don’t think its a Sparton – I’m pretty sure its a Stromberg Carlson – it looks like one for sure – and it looks like it has an Acoustical Labyrinth – hard to tell from your pics – maybe its a 345 – schematics here – https://www.nostalgiaair.org/PagesByMode … 021479.pdf
    If it is – congratulations – you’re gonna love how it sounds – and it should be a valuable radio – corner radios like that are usually very sought after.

    Here’s a listing for a 345V – same dial and knob layout – different cabinet https://picclick.com/Stromberg-Carlson-M … 69739.html

    Thank you Steve,,,I don’t know what happened when I typed in the name of the radio because I knew what brand it was.
    For some reason I have a hard time finding schematics at nostalgia air.. Maybe you can let me know how you found it so easily.. I think I am just not clicking on the right stuff.
    Thanks again for the schematics.I just hope that the radio has the caps marked on them, so I will know the values
    It sounds like it is quite a system..{ acoustical Labrynth]
    It sounds like you have one of these ? If you do let me know if there is anything I should know about in recapping it. Also I am going to need the little plastic star that is on the right side of the dial.. it lights up when you are on SW,or pushbutton mode. And as you see I will be needing two knobs
    I am going to do this radio for a friend and all I have seen are the same as you ,,,,,just two photos. I have a Stromberg Carlson with two bands that I refinished and it sounds very good and picks up far away stations very good. Here are a couple of photos of it

    The only thing I could add about recapping it would be to change out all the resistors while you’re at it – when I started redoing radios 25 years ago – I felt that I could trust most of the resistors – other than the abviously overheated ones – but lately , now that they are 25 years older I’m having more problems with them – I hate having to open a radio twice – and it looks bad to the end user when it fails shortly after having been repaired – I’ve found that original resistors that check good will quite often fail after they’ve been subjected to cycles of heating and cooling – perhaps in a lot of caes its because they haven’t been subjected to voltage and temperature variations for a long , long time.
    At any rate – they’re cheap – so why not change them out whilr you’ve got everything in front of you. Stromberg Carlson’s of that vintage have some pretty poor 1/4 watt resistors – especially the 270k , 470 k and 1 meg – just about always bad. working on that chassis should be ok – its plenty deep and big.
    I’ll see if I can post a pic of my favourite Stromberg – I’ve done three of them – with a couple waiting in the wings – great radios – tuning eye , good short wave reception, Acoustical labyrinth – and a built in drum antenna with antenna control knob in the front – you didn’t have to reach inside the back of the radio to turn the antenna. This is an older pic – nowadays I would add some toning to the finish . Gotta love that veneer though.
