    Why is it so hard to find ceramic capacitor kits that have a 3.3pF in it?

    Thanks for the explanation. I found a kit that has a 3pf in it. I am hoping I can get away with that

    Part Replacement in Circuit

    Thanks Bertus. I will certainly check them out. The only reason I leaned toward this one, was that he has a detailed video putting it together on a breadboard. He says that Thermanins that have volume controls, get very complex. That is why I stayed away from othe rones. But if I can find a...

    Part Replacement in Circuit

    I am trying to build this circuit and gathering all the parts: . The schematic for it is at 6:50 of the video. It is a Theramin- which is a musical gadget of sorts. It makes zany noises when your hand moves toward it. To see Lez Zeppelin use, one, see 6:15 of this...

    Weird Voltage divider issue

    Thank-you folks. What I have concluded is that any of a number of things could have caused this. The major learning from this round, is to use strip board. I used PCB which necessitated a lot more wiring and soldering than had I used strip board. So, i just built the voltage divider on strip...

    Weird Voltage divider issue

    You're right. i did not use a breadboard. I used a PCB. The resistor did appear to be faulty after measuring it. When i connected a new one, i got the half voltage- but only momentarily. Then it went to over 8 volts. When i get time I am going to redo this pedal again. I think I'll also move to...

    Weird Voltage divider issue

    I drew a pic of how I hooked it up. The dotted circular area is what i am particularly unsure of

    Weird Voltage divider issue

    Hi Harald: It's a mystery to me because the night prior, the entire pedal was working. The next morning, i try it again and it was not working. I checked the voltages to the pins, and it seemed like the voltage was no longer being divided. I replaced one of the resistors which I thought may...

    Weird Voltage divider issue

    Sorry Harald. This might help further define the issue. I don't need help with the entire circuit. For whatever reason, i have a mental block which causes me to sometimes build the voltage divider correctly, and sometime not. For the ones I have done correctly, they are already glued into...

    Weird Voltage divider issue

    So, I have been building this same circuit, a number of ways (see circuit here:https://www.electronicspoint.com/forums/threads/a-stretch.293212/ I used a LM741 op amp and it worked. Did the same circuit, this time incorporating an additional resistor as suggested by AudioGuru- and it worked...

    Yes. Mood for a Day. Don’t compare my version. I used to be able to play it flawlessly. Not now

    ok AudioGuru-- I whipped this up just for you, on an acoustic with no awful distortion..lol see if you can guess this piece. I'll give you a hint., It is kind of related to the word "No" https://drive.google.com/file/d/1PJVlGsUXLG7cE5qUitcWSvwRsOh9L5Ay/view?usp=sharing BTW..this is not easy...

    I think we may be violently agreeing ;-) But first let me clarify something. The last recordings you heard, were using a plug in. I did not use a pedal. I simply plugged my electric guitar directly into my audio interface, and then streamed it through a plug in that is served up through my...

    I am rusty on that front. I used to play that on acoustic with the right notes and it sounded great. Thanks for listening

    Sorry but as I mentioned in the post below, i did not use nthe box I built for this recording. Here is my post: Well, this thread may have taken a slightly different musical turn. Some of you may be interested in this. Despite all the hardware stompboxes., some of the best sound these days, can...

    No....not the pentatonic scale.

    Recommendation for side cutters

    Can anyone recommend a decent pair of side cutters? Mine is a cheap one and it's already busted. What I mean is the pliers that flush up against a connection, to snip it off. Preferably something I can find on Amazon. Thank-you

    Well, this thread may have taken a slightly different musical turn. Some of you may be interested in this. Despite all the hardware stompboxes., some of the best sound these days, can be had by software plug ins. For Santana fans, you may enjoy this. I solo'ed to a Sanatana type backing track...
