However, that is where you stop. Caddock resistors do not measure better than other low inductance resistors....in fact, they do not sound nearly as good as parallel Nude Vishays....
Caddock has several model lines. The most commonly available ones are as you say. But they make others which have to be custom ordered and they are better than the Vishays. Vishay owns Caddock FWIW, and has seen fit to not mess with them when they bought Caddock out.
Ralph.....you sure have a fear of radiation.....maybe make a faraday cage to live in. I have been modding class D amps for 20 years and no one has died of radiation poisoning.....or had birdies or whistles or whatever your fear is.
We have to meet FCC and EU Directives (for the CE mark) since we’re an actual company. The CE mark is required for export to Europe. Some of the equipment that you worked on may have borne the CE or FCC mark; which means that it may have done so illegally after modification. Quite often that escapes notice but it can be a pain for the owner if they don’t realize why their tuner has so much interference. If you’re not doing testing you are doing your customers no favors; makes no difference how long you might have been doing the work other than it might mean a greater legacy of interference.
If you were to measure and certify the noise generated, you might on occasion find a unit that does not meet criteria right out of the box and you might be able to come up with a fix. But without radiation measurement you’ll have no idea.
No one....including me.....listens to everything....there is just not time. That is why the first thing to do when tweaking is to eliminate everything that is not needed......like LEDs, output connectors, extra connections, extra fuses, steel bolts and plates holding transformers down, etc......all these things mess up the sound.
This is speculation on your part.
I’ll give you a little tip: most toroid transformer manufacturers will include a steel bolt for mounting the part. But if you use it and spend some time with the installation, you’ll find that the bolt gets hotter than the transformer since its a magnetic short. We found this out back in the 1980s and so use non-magnetic stainless bolts. This causes the transformer to draw less current and run cooler.
My point here is you have jumped to a conclusion based on a made up story about what we do or don’t do. If you want street cred, refrain from talking about things of which you have no idea.
