Clement S asked:
I 'm. re currently a tape recorder reel to reel of the year, using an amplifier of the valve (tube). It works well, but there 'so S.A. little bit of buzz, the valves? in good condition, but I have to replace some of the filter capacitors. I need two 16 microfarad lle protections from 275 volt and two 32 microfarad lle protections from 375 volts. I don 't know where to obtain them. I 'the VE has observed all over the web, but just chamfer the discovery of what I need. Suggestions? ? memory of there electronic local Newmarket near where I live in what store?

Ste P asked:
1.Can an ultrasonic transducer (inexpensive) commercial that has a frequency of 40kHz concentrate be used to generate ultrasonic waves of 18kHz to 2MHz. 2.The aim to generate ultrasonic waves through a transducer and an amplifier and I wear the `t know what it is best used as transducer. 3.Can a piezo-electric tweeter be used? 4.Can ultrasonic waves be concentrated using a parable? 5.I want to generate cavitation in a liquid in a tube and I thought that the best way was to use ultrasonic waves at high power. How do I calculate the correct length of a tube as a frequency specific? Thank you.
