Tube Master Clock

A tube clock is a very useful thing for enjoying music. More than 20 years ago, I first tested such a device and really liked the resulting effect. For the first time I heard my favorite CDs in a quality that was close to vinyl. Before that they seemed hopeless to me.
The tube master clock very effectively transformers the sound of digital devices into something attractive.
Where can we use it? Previously, these were CD players and CD transports.
Typical frequencies:
4.2336 MHz Philips first generation of CD players : CD100, CD200, CD300, CD303, CD101
8.4672MHz Japanese devices
11.2896 MHz Philips second and third generation of CD players
16.9344 MHz Japanese devices- Sony, Denon, JVC, Pioneer, Yamaha and many others.

We can also use tube clock in USB converters with 12.00 MHz and 24.00 MHz

Nowadays more complex USB converters with two switching clocks are used, for example Amanero:
22.5792 MHz and 24.576 MHz

I would like to draw your attention once again — this is not a Word Clock, this is a Master Clock, that is dividing in digital processors to the word clock and bit clock. Word Clock is more of a device for a sound studio than for home audio. We do not make that kind of stuff.

We have made many different tube clocks based on different tubes, but the device shown in the photo uses very old German military tubes. These tubes have very good sound and they are extremely reliable. Unfortunately they are becoming rare and one day we will have to switch to other types of tubes. However, for now we still offer this model in a separate case with two outputs.

Specifications:

1. Frequency — set at the customer’s request, from 4 MHz to 25 MHz, not higher, since the clock operates using the first harmonic of a quartz resonator.
2. Supply voltage 115 or 230V AC (pre-order)
3. Output voltage depends on frequency and is 0.5…1V rms
