Lovepedal jubilee vero build help

[Ad]

I'm getting a weird oscillation and high pitched feedback when I stop playing. I can hear the OD and guitar through the sputtering noise. I am playing through a test box I built with rather long alligator leads doe my I/O and 9v, ground leads. Lm386 chip gets too hot to even touch. Here are my voltage readings.
1, 1.33
2, 0
3, 0
4, 0
5, 5.38
6, 9.30
7, 4.66
8, 1.33

Also, my gain pot is a b500k not an A250k as called for in schematic

Are you sure you are using LM386D?. Some people reported issues with other types of this IC.

There are 1/4W, 1/2W, 1W output versions. The D, L, N-1 has 1/4W.

A few days ago I breadboarded the jubilee with 386L (still there) and the sound is very nice.

The LM386 gain is adjusted between pins 1 and 8, you must see the datasheet and check this.

Your pot I think is not the right one, you could try with a 470k between lugs 1 and 3 to decrease the value +/- 250K..   ..linear response.

I believe its just a lm386 heres a pic. Yeah the gain pot is definitely not the right one but I figured I'd give it a shot anyway. So a 470k resistor between lugs 1 and 3 ? Awesome. I appreciate the help. I thought it was stray capacitance due to the long leads on my test box but then i felt how hot the lm386 was and I knew it was something involving that. So I googled about the chip and read other people having issues with the same chip.

hello Ad, welcome to the forum.




I think the top leg of your cap is one row low.

That's exactly what it was. Thanks for the help. Much appreciated.
