Det är kul när en mod blir bra, tänker på min högtalarmod, en fråga från en novis i elektronikmod. - behöver en axiel filmkonsensator inte ha samma värde som en elektrolyt? Har jag missat nåt här?
Att filmkondesatorer i signalvägen låter bättre än en elektrolyt i signalvägen är Iofs vedertaget, ska inte värdet vara samma?

Jaha, men jag menar, har filmkondingar någon egenskap som gör att du kan ersätta ett högt värde (elektrolyt) med ett betydligt lägre(filmkonding)?

Nearest one that does something similar is going to cost you... A LOT..actually..£175

Tack! Det blir nog till att beställa en lite julklapp till mig själv!

Valab 11.2896 & 5.6448 MHz Tempeture Compensated Crystal Oscillator Module
________________________________________
Almost all aduio builders know upgrading precision clock in your dac or cd player is most rewarding investment in digital source. So precision crystal Oscillator become so popular parts in audio tweaking market. While you may not know precison clock need very stable and low noise power supply to get right performance. Direct replacement can only obtain marginal benifit of your expensive investent.
Here we supply our clock upgrade module to critical aduo builder. In this module we integrate 2 stage voltage regulaor to supply very clean low noise power to our custom ordered 1ppm tcxo. And after tcxo clock out, we use one 74h163n high speed and low impedance driver for clock signal output. This clock module must be best clock upgrade kit in audio tweaking market. We will also use this module in our great credit NOS 1543 DAC in next version.

Features of this precision clock module:

1. Clock generator : 1ppm 11.2896 MHz TCXO /Waveform: TTL/CMOS / Phase Noise: -125dBc/1KHz /Aging: 2ppm per year.
2. Two stage voltage regulator by TL431 to offer very low noise power to TCXO, which is critical to get frequency stability of TCXO.
3. High speed and low output impedance 74h163n wave buffer for clock signal.
a. It will benifit to get stable and anti noise clock signal.
b. It also supply frequency division, so you can get not only 11.2896 but also 5.6448 and 2.8224 MHz clock signal simutanuously.
3. If your digital system need both frequenc listed above, you can offer two clock from synchronal clock source with minimal jitter.
4. High quality parts used in this module like Phlips BC 036 and Panasonic FM capacitor, Dale military resistor and high speed/low noise diode.
5. This module should feed 8~12vac (1A or higher current) power input
