Tivoli Audio Model One FCC ID issue

[Jack Crow]

All,
A client gave me a repair to look at this week.

It's one of those up scale entertainment radios.

A Tivoli Audio or Henry Kloss Model One.

This is a premium radio, very good sound, feel, and performance.
The price is in the 150 buck range.

A casual web search indicates the company refuses to publish service data on the unit. Something to do with patents.

OK, there is a way around that, sometimes.

When ever a product is to be sold in the US it has to meet electrical standards.

Those are done at what are called FCC Labs.

So each item sold in the US needs to have an FCC number.
From that you can very often find service data that has to be submitted at the time of testing.

Sneaky and nasty, but that is how it is in this business.

Tried to look up the FCC ID Number.
Could not even find the FCC number on this unit!

I expect this on illegal cable boxes, CB Linear Amplifiers, and 'export radios'.

Just wondering how this slipped by.

Very weird.

Be well all.

You should post pictures of it, are you sure its not fake? I too am wondering what circuits make this thing sound good.

Guys,
To answer your questions.

Ben,
Why it sounds good?

The easy answer is the case is made with an internal ported speaker.
It has bass and high end.
Wider than standard AM filters and a very potent for a tiny box audio amp.
It's the same kind of thing that makes other similar high end products sound good.

Like the Bose wave radio.

This unit is not cheap. They sell for about $150 each.
That is real pricey for a table radio.
The web photo is a clone of the unit I had on the desk.

Nines'
The problem was weird. Yet that is the kind I tend to collect.

The client complained about 'inter station noise' the crap we here when an analog tuner is adjusted across the dial. The radio lacks 'stereo muting' so all that FM crap oozes through until it detects a channel.
Anyhow, I heard it make a god awful noise inter station noise in the clients home.

It was so bad at first I thought the tuner was a veractor tuned device, and the tuning pot was dirty.

When I cracked the case, this theory was a 'non starter'.

There is a gear train similar to 'anti back lash' gears that connect the tuning knob to the shaft of what looks like a standard multi gang tuning cap of the type used in small portable radios.

Anyhow, I get the radio home and the inter station noise seems to be normal, and not the screeching horror I heard at the clients home.

So the problem is something in the house getting into the radio and not a radio defect.

I looked it over, decided it is normal and will be returning it to the client.

It is un ethical to fix what is not broken.

That is the news.

Re: Tivoli Audio Model One FCC ID issue

I have some experience with these products. I can't say much about the FCC ID and never gave that topic a thought. They are cheaply made junk with a ported bass so they go boom boom. The typical consumer equates boom boom with high quality audio. Most of the problems in these radios have to do with loose connections caused by jamming in the 12 volt adaptor. That can be fixed, but working on the front end tuning characteristics is out of the question. Even if you had a schematic and some idea of what to look for you would have a very hard time getting it into a service position or finding suitable test points. The company that imports the things from abroad does not fix them or know anything about them. The schematics exist somewhere in China, Korea or India. Warranty replacement only. Similar to many other home entertainment offerings in that respect.
