I use the new Pasco.
It has the required fine tuning for this demo. Although it has a small
internal amp, an additional external 30 Watt amplifier is still
required. Jerry

Do a little more of that work which you have confessed to be good,
Which you feel that society and your most Just Judge rightly demand of you.
Cultivate the tree which you have found to bear fruit in your soil.
If you have any experiments you would like to try, try them.
Now's your chance.
