Difficult to read or understand? What purpose would a fake vacuum tube serve? Some new ones are small, as on some phono preamps, butthey are not fake.
Some high resolution CD players or transport only no DAC types cost over $1,000.
In that overpriced hunk of junk CD player that came into my shop, those "fake" tubes were actually real glass tubes, similar to 12AX7's, and epoxied in place to prevent removal.
However they were
only wired to make their filaments illuminate for a realistic impressive "appearance".
The rest of the circuitry was all solid state - IC chips that had their identification markings ground off, so that no one could figure out what they were - a common chinese tactic to prevent any service tech from troubleshooting a product.
I've seen this same thing done in tv sets, and radios too.
That cheap plastic Sony CD mechanism had a dead motor, and when I researched the part number of the mech on my distributer's website, it was an unavailable older mech that was used in older discontinued 1980's boomboxes.
If it had been available, it's cost would be $8.00 plus shipping.
Certainly it was not something that would be used in something considered to be expensive High Quality.
The case, enclosure, of this CD player was extremely impressive 1/4 inch thick polished aluminum with massive feet "towers" at each corner, and finely finished anodized, making the unit eye-catching and heavy if picked up.
And the bottom cover plate was secured with at least 20 screws to deter anyone from looking at the mess inside.
You have to understand, they build things this way to fool the consumer that they're getting something of high quality, so they can charge rediculous prices for something.
They put more work into "looks-styling", because they know that people have superficial weaknesses, judging something by appearance.
And this obviously also applies to anything.
I had a cute AM-FM clock radio come in for repair once, and it appeared to be a genuine "vintage" Emerson from the 1950's.
The thing was heavy if picked up, making it seem like a quality product.
But when I took the back off to troubleshoot it, it had a damn concrete brick glued inside with a cheap transistor radio circuit board.
Again, Superficially is used to fool people.
Or as they say: "Looks can be deceiving".
