Everything is worth "something" to somebody, even if just for parts, or to knock apart and use for an extra shelf in the pantry
The problem is always how much is it worth to "that" somebody.
It's not a high end big brand unit with 15 or 20 tubes that would spark interest from most collectors, so unless you can find a buyer who is looking for a radiogram in the 60's retro style to match their decor, or a person who wants that particular model for sentimental reasons because their parents or grandparents owned one, then it's probably not worth anymore than the price of a pack or 2 of cigarettes to most collectors.
These old units must have electronic restoration work carried out to make them safe to use with regular use, but unless you can do this yourself, you can easily spend between $100-$200 to have the mechanical and electronic restoration done for you, only to find that it's still only worth 1/4 of the cost.
If you have a record collection from the 50s to 70s era that you intend on playing regularly & want that "authentic" sound, then you could probably justify the restoration cost as you'd get great sound from your record collection for the next 20 or 30 yrs, without spending any more apart from occasional replacement cartridges &/or styli.
If however, you're hoping to invest in it's restoration and turn it over to make a quick buck, then I'm afraid the news is all bad (at this point in time).
There is of course a chance that in another 20 or 30 yrs, when these types of models have a bit more age to them, they will become more "collectible" and sell for what they
should be worth, but for now, even the more collectible RCAs & Magnovox etc are seldom a profitable undertaking if you have to pay for the necessary restorations to be done. The parts are generally cheap, but the man hours involved with checking all components & circuitry, replacing capacitors etc etc are usually many.
That said, I dont think your Perpetuum is trash & deserves to end up as land fill.
It's very complete, having the legs, instructions & other paperwork, and appears to be in fairly good cosmetic condition, which are all a plus.
If you prefer Beatles CDs over records, are not interested in having it restored or hassles of trying to sell it, then there are better alternatives to dumping it on the footpath.
Next time you go to the supermarket, bottle shop or church, throw it in the car & drop it off at an op-shop, or give it to someone on the white elephant stall at the next school fete or church yard sale.
Even if they only get $2 for it, the money is going to a good cause, the Perpetuum is given the chance to find a new owner, and you've done something to help recyle and preserve a small part of history.
