I am getting very loud continuous buzzing along with a very quiet fuzz guitar sound. Voltages across the transistors are: <br /><br />2N3904 NPN Transistor<br />- Collector to Emitter 1.05V<br />- Collector to Base 0.59V<br />- Emitter to Base 0.33V<br /><br /><br />BC182L NPN Transistor<br />- Collector to Emitter 0.67V<br />- Collector to Base 0.67<br />- Emitter to Base 0V<br /><br />My input voltage is just under 8V (i'm using a battery that isn't completely full to test, but this should still work / wouldn't cause this issue, right?)<br /><br />The voltage across the two legs of the 47uF cap is also just under 8V.<br /><br />Any advice would be much appreciated, thanks!Anonymoushttps://www.blogger.com/profile/14157441807019466270noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-52774401514949048532021-03-16T10:26:41.549+00:002021-03-16T10:26:41.549+00:00I've tried to put this one together but haven&...I've tried to put this one together but haven't had any luck with testing it. I've got a test box I use that basically just has alligator clips for input, output, 9v and ground, I usually just clip them on to whatever circuit I'm testing and off I go, but this one has thrown me with the extra ground from the board and the LED so I'm not sure I'm even hooking it up right to test. <br />Anyway, I'm not getting any sound out of it at the moment. One thing I realised I stuff up was the pinouts for the subbed transistor I used for the BC182 (I used another 2n3904 just to test). I'm assuming you have to sort of bend the pins around a bit so they match the BC182 pinouts? Is there anything else I've got glaringly wrong?<br />Cheers<br />https://imgur.com/gallery/S3lZGk7<br />Reinholderhttps://www.blogger.com/profile/14064468610766603152noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-72693590944361889652020-12-02T11:22:27.006+00:002020-12-02T11:22:27.006+00:00Take a look at the Meathead Deluxe layout that'...Take a look at the Meathead Deluxe layout that's also on this page.

If I'm using a "3pdt PCB" that has a CLR built in, would it be better to leave it off of the main board or the 3pdt board, or does it really matter whcih? If it would be better leave off the main board, would it be okay to make it 1 column narrower? Sorry, I'm very new to this!

What I am curious about is that in this build there is a direct link from Q1 emitter to ground but on the D*A*M Meathead there is a resistor (unknown) from the emitter to the input and 10nf cap junction. Why or what is the difference? Why was it omitted and what is the resistor value?
