Keep radio original, or improve it?
My own experience with the speaker on my 1935 Defiant, which I was tempted to replace at one point, and some recent threads such as the 'Murphy with hum' have got me wondering.
How much of a compromise to sound quality and performance are people ready to tolerate for the sake of maintaining originality? At what point does modifying a set to improve performance start to devalue it? Gabriel |

Re: Keep radio original, or improve it?
Unless you have a set that of such rarity and splendour to be of interest to a major auction house, there’s relatively little loss or gain either way. A set that doesn’t communicate is just a relic, even if fascinating to us. One that works can continue to give us joy and that’s probably justification enough.
So I’m all for mods that provide this kind of joy, whether just for us or for others. Amd of course it’s nice to have a couple of sets that are intact, but there not intrinsic virtue in it. Our focus of attention is no more worthy than collecting lawn mowers or vintage camera lenses, horses for courses !

Re: Keep radio original, or improve it?
I'm a bit of a purest and like to get my radios looking and sounding as close to how they were when new or newish.
I think once you modify them you could risk losing the original essence and charm. Kind of like putting a high performance engine into a Morris Minor or putting double glazed windows in a Victorian house!

Re: Keep radio original, or improve it?
I do sometimes find the old 1930’s sets have slightly muffled sound, and ones with a tone control sound too shrill when you try to correct the muffled sound with it. I have been experimenting with a completely reversible mod, fitting a tweeter! In sets with large speakers you can easily hide it in front of the speaker just behind the cloth, and you can either connect it directly to the speaker terminals, or just run some wires with plugs on to the extension speaker sockets.

Re: Keep radio original, or improve it?
The thing is, Clive, I want to be able to enjoy the way they sound. If they sound too "mellow bellow" for example, they will end up being display pieces only.
Having said this, if it's a particularly valuable or old set I'd probably be quite a bit more conservative. |

Re: Keep radio original, or improve it?
Apart from curing a fault that has developed or replacing known trouble makers I can't see the point in wanting to make a manufactured radio receiver "better", the circuit design and the rest of it is what it is.

Re: Keep radio original, or improve it?
You wouldn't modify the DAC90A to make it sound better Lawrence?

Re: Keep radio original, or improve it?
Just snip that tone correction cap on a DAC90 and all that lost treble and clarity reappears. Want it original? Solder it again. Nothing wrong with sympathetic mods in my opinion, especially when they're easily reversed. Drop a trannie chassis into a thirties art deco set (for example) - no.

Re: Keep radio original, or improve it?
I have an RGD radiogram that has undergone considerable modification to the amplifier. I wanted to be able to use it to provide as good a quality sound as was reasonably possible, whilst still keeping the electronics in tune with the period (1953). It is not one of the more valuable or rare types, otherwise it would have been kept original. However, I use it regularly and get much enjoyment from it.
It was in a bit of a state when I got it, the original output transformer was open circuit on the primary so that was my excuse to try and improve.... https://www.radios-tv.co.uk/communit...r-desecration/

Re: Keep radio original, or improve it?
It does make a surprising difference! And yes, through the gram input is where it really makes a difference. I do tend to listen to a lot of heavy metal type music, which these sets weren't really designed to play! But last year when Absolute radio did their day of 'Absolute 40's' I had that playing in the garden on the Ekco AC86, without the tweeter mod, and it sounded really nice with the old 40's tunes playing, for that type of music it didn't need anything adding to it at all.

Re: Keep radio original, or improve it?
I can't see the sense of 'improving' vintage technology, it is what it is. If you want something better buy a new one!

Re: Keep radio original, or improve it?
Each to his own, but, yes, I'm another for whom an essential part of the joy of using vintage equipment is experiencing just the quality of sound its period design results in: which can include hearing the results when music of a later origin is played through that equipment. If any simple measure would significantly improve the sound quality of my main stereo system I'd probably be up for that, because although the system is bordering on vintage (40 year old amplifier, 55 year old speakers) it's in the house to produce the best listening experience I've seen fit to pay for. So I use it when I want to listen to music, and use a valve radio when I want to listen to a valve radio.

Re: Keep radio original, or improve it?
I'd just add a plea - if modifying the circuit in any way, glue a label with information as to the modification inside the case, so future repairers are not puzzled. I've had two or three sets on my bench that have been "improved" and all of them have given me the trouble of working out what some other chap has done with them!

Re: Keep radio original, or improve it?
One man's improvement is another man's desecration.
If it's your equipment, it becomes your choice. Whichever way you choose, there will be criticism from the opposite camp. Skin-thickening exercises are advised. David
