    120 VAC Power Conditioner

    OK I think I got everything together here. It was a good exercise because I think I figured out some more stuff. Transformer: Resistance between C & A (300+/-) Resistance between C & B (300+/-) Open between A & B The resistances seemed to move around a bit, but the one resistance that kept...

    Will do! Thank you.

    120 VAC Power Conditioner

    This 120 VAC Power Conditioner has its transformer disconnected and it needs to be reconnected. My skill level isn't quite there yet to be 100% certain on the wiring, so I'd like advice please connecting wires. This should be pretty easy for an experienced person. The circuit board has four...

    Dimmer Circuit with Switch Wiring Question

    Thank you guys for helping me. I know this dimmer circuit looks like junk, but I did not build any of, I am just connecting wires. The dimmer circuit was made by LUTRON. It came in a black plastic box for mounting in a wall. The TRIAC was riveted to the aluminum front plate. I ground off the...

    Dimmer Circuit with Switch Wiring Question

    I did not buy this, I am trying to fix something for my wife and her lab. I thought someone would know how to help me. - - - Updated - - - Yes, THANK YOU. Actually, the entire dimmer circuit is factory made. The TRIAC is "free-floating" as it was in the plastic box it came in. This is Not my...

    Dimmer Circuit with Switch Wiring Question

    There are no diagrams for anything. The colors of the wire mean nothing in this case (this is Brazil, I've seen paperclips and twist ties used in place of wire, so...). It is a store bought dimmer with two wires coming out. It was made to go where a wall switch for a light goes. There is a...

    Dimmer Circuit with Switch Wiring Question

    I should add here that those "connections" are not real connections -- that is just the wires touching each other to show where it would be connected (soldered).

    Dimmer Circuit with Switch Wiring Question

    Can someone please help me wire this circuit? This is working with mains power and I do not feel comfortable doing this without some knowledgeable help. The dimmer circuit is store bought. It has two black wires coming out of it. One of them is already wired to the toggle switch. The toggle...

    Capacitors for Amp Circuit

    I can barely (ear to the speaker) hear it with a megaboom speaker. My headphones can play it a little better. It is more like I notice it is gone when I shut it off and hear silence. The speakers I am using for this project are decent 4.0 Ohm speakers. I soldered everything yesterday and it...

    Capacitors for Amp Circuit

    It is especially helpful to have the practical effects and an "overall picture" of what you hear, based on the numbers, described -- especially comparing different size capacitors, in this case. I found an online tone generator last night that helped a lot too. Thank You!

    Capacitors for Amp Circuit

    Not really too concerned. Only concerned enough to post some questions.

    Capacitors for Amp Circuit

    I am using a 12v power supply. But, the circuit works best closer to 16-18v (so I read). Eventually, I will have other power supply options, so I would rather plan for that. So, I will go for the 25v. My main concern now is whether I should go with 0.1uF or 1uF input capacitors. Will it really...

    Capacitors for Amp Circuit

    I think I will try out the 0.1uF input capacitors with 1000uF output capacitors. edit: I forgot to ask... For the output capacitors to the speakers what will happen if I use 1000uF/16v instead of 1000uF/25v? Is there going to be a difference in sound?

    Capacitors for Amp Circuit

    OK, I think I understand the relationship a little better -- still a long way to go. This is my first circuit from scratch. After some searching, I was able to find a few 0.10uF and 0.47uF (and have one 1.0uF) capacitors and also the datasheet you mentioned with the 0.22uF capacitors. So, would...

    Capacitors for Amp Circuit

    The datasheet for the TDA1517 has a sample circuit that calls for two, 1uF capacitors for the left and right inputs (pins 1 and 9). In a pinch. can I use 10uF capacitors? What difference to the sound would it make? Thank You.
