Quote from: rockaffe on April 17, 2023, 02:31:14 PMHello everyone, I'm doing the veroboard layout for the honey amp but, as I'm not yet very familiar with reading schematics, I'd like to ask for some advice.
The first concerns the connection of the headphone jack, which I solved as follows:

You cannot view this attachment.

Is that correct?

The second concerns this part of the circuit:

You cannot view this attachment.

Does it mean that pins 1 and 8 of the IC need to be connected to lugs 1 and 2 of the gain pot?

Thank you!

Do you mean you are creating your own vero layout?  I haven't seen one for this yet.

Regarding the headphone jack, it is designed for a switching jack.  You have the blue line connecting two pins and it shouldn't do this.  It should go from board to the jack, then jack to the speaker.  When nothing is plugged in it goes straight to the speaker, when something is plugged in, it cuts off the speaker and only goes to the phones.

Regarding the gain pads, these can be left unpopulated.  The regular gain control goes inline at the start of the circuit (effectively a volume control before the preamp stage).  Those two gain pads are for increasing the gain of the power amp (lm386).  With a bunch of testing, I've found that I can get any more clean volume out of the lm386 at more than the stock 20x gain setting.  If you want more gain though, crank it up!

Thanks for your time! Yes, I'm creating a vero layout for this one.

Thank you all for this informations, they're very helpful.
Just one last question: I've tried to follow all the "beginner links" in other forum threads, but a lot of them (almost everyone) not work anymore. So, do you guys have some beginner resources to link?
Thanks again for your time.

I'm from a very small town in Italy, not so easy to find a mentor. BTW, I do my own repairs on a tube amp, so I'm already aware of risks and how to avoid them.

Are you able to make your own PCB ?
Are you going to want reverb ?
Are you after clean tones or overdriven like Marshall etc?
It all depends on what sort of music you like to play.

There are some pre-amplifier pedal kits around if you want to go that way.
You would need a separate power amp pedal to go with the pre amp pedal.

You will need to provide a little bit more information so we know what you will like to build.

And lastly, welcome to the forum. :)



Thanks for your answers guys!
So, I'd be interested in learning how to build everything by myself, without the aid of kits. At the moment I build on perfboard, waiting to learn how to make pcbs well.
I mostly play rock and blues music, so I'd like to work on something that has the ability to have both a clean and a distorted channel.

Hi everyone!
I'm a novice amp builder and for about a year now I've been building guitar effects and small amps (little gem, noisy cricket etc.)
I don't have great knowledge of electronics, but I'm trying to catch up by studying as much as possible.
My welcome question would be this, if anyone has the time and willingness to help me: if you were to recommend to a beginner a first amplifier a little more "serious" than those mentioned above, what would it be?
And if you had to indicate suitable readings for the beginner himself, what would they be?
I thank all those who will spend a few minutes to give me a hand.
(And pardon the English, translated thanks to Google)

HI!
