plates and insulate to couple of kv, you have a simple electrostatic
speaker. Just find or wind a tranny to step up the audio output.

Hello all;
I have a NEC  TV, model fs-5185 (51 cm) that over the last couple of months
has a wierd fault of intermittently making a 'ticking' noise, and the screen

I don't know the trick for removing the plastic insert from the metal shell
in order to solder the terminals.

G'day all,

Hi group,
I repaired a PC power supply L&C model LC-235ATX. I found some
articles requesting some component values because this PS blows so
spectacularly. I'm posting these component values that usually blow

I wish to construct some solid state relays to control some lighting and
heating. I plan on using a MOC3041/2 Optoisolator which I have in my parts
drawer.
Can anybody recommend a very commonly available and cheap Triac to use. The
