Hi Steve,
The Model One and PAL are classic Henry Kloss designs. We worked
together for many years, from the mid-80's until his death in 2002. I
started at Advent in 1972, with the Model 400 as my first FM tuner.
Henry was wonderful at recognizing combinations of new and old
technologies that would make new and useful products, and then pushing
them out as quickly as possible to the market. He conceived the Model
One and designed its' acoustics, controls and basic appearance, and
financed and project managed. I provided the electronic design which
satisfied his requirements for ease of use, high FM dynamic range, low
audio distortion, and precise acoustic frequency response
equalization. The PAL is the same idea of performance, simplicity and
good sound taken into a smaller, portable package. The designs are
licensed to Tivoli Audio for manufacture and sales.
Again, I do NOT speak for Tivoli or anyone but me, and I am not
involved with any Tivoli products besides the Model One or PAL.

Hi G.C.,

PMFJI, but since you seem to be quite famililar with the Tivoli radios,
I would like to ask you a question.

I have a Model One and I am quite satisfied with it, particularly on
FM. There is a fly in the ointment, though. There is some hum coming
from the loudspeaker all the time when it is on. If I turn down the volume,
the hum from the speaker is still there.

If I turn off the loudspeaker by plugging in earphones, the speaker
off course becomes silent - and there is no humming sound in the
earphones, so the hum seems to be added at the final AF stage
driving the speaker.

Is this a common thing with the Model Ones, or would you advise
me to have this checked with the supplier?

TIA & rgds,

Kim

G. Cook,

Thanks for the info! Great designs!

Steve

G Cook,

Thanks for the info. I thought Henry Kloss designed those radios? Was
it a collaboration?

Also, who sells external ferrite antennas? Also, what is a Hi Q
antenna?

Thanks again,
Steve

Hi Kim,
I would email Tivoli, they may have a suggestion. I believe that the
220VAC versions have gotten complaints about hum, if that is what you
have. If that is the case then an external supply would eliminate the
hum, 12VDC at 700mA is what you need. The DC connector is standard
2.1/5.5mm plug with center positive.
