Pocket electric guitar combo



At first glance, the KDPV shows an ordinary pocket-sized radio, released in the nineties or zero. But the function of a guitar combo is added to it, which is very convenient, since there are almost no ready-made pocket combos. He is low-power, but powerful at home and not required. Minimum alteration is required, with or without the original function, and what exactly needs to be done - the author of Instructables says this under the nickname mhuerta2.

To remake the radio, you need two wires with a cross section of 24 to 28 AWG, which corresponds to a range of 0.3 to 0.5 mm2as well as a 6.3 mm jack jack, which corresponds to the plugs on the cables of most electric guitars.

Pocket electric guitar combo



The master opens the radio case and discovers a generally standard board there: a magnetic antenna, a variable capacitor, coils with trimmers, a microcircuit, and other components.




The receiver’s magnetic antenna is used only for reception in the medium wavelength range. If there are no mid-wave radio stations in your area, you can have a snack from the wires going from it to the board. Then the range switch will be simultaneously the mode switch: the VHF range is selected - the radio is used for its intended purpose, the CB range is selected - only the signal from the electric guitar passes. If you live, for example, in St. Petersburg, where there are medium-wave radio stations, you do not need to disconnect anything. When playing the electric guitar in this case, you have to tune the receiver to an unoccupied part of the range, resigned to the fact that a quiet hiss will be superimposed on the music.



By applying a “crocodile” clamp with a signal from an electric guitar to various outputs of a variable volume control resistor, the master determines which ones are suitable for this. But random action is not necessary. You can immediately connect the jack housing to the receiver’s common wire, and the remaining pin of the jack to that of the side terminals of the variable resistor, which is not connected to the common wire. If this resistor lead is connected with an additional switch, then to the socket, then to the conductor going to it on the radio board, you will not have to do any manipulations with the magnetic antenna. All functions of the receiver will be saved, and they can be selected separately.

The master once again makes sure that everything works while connecting the electric guitar like this:



And then plugs in the jack:




Drills a hole in the radio housing for the socket and installs it:




Connects an electric guitar and plays:




The battery compartment of most of these receivers is designed for two AA elements. They can be replaced by two batteries of the same type, which is convenient when using budget chargers that can charge such batteries only in pairs.

No, we are talking about the D class in relation to the guitar sound.

I was repairing a combo with this circuit.
Googled. So this is a completely different conversation, this is the hall equipment, and we are talking about a pocket combo. Well, that’s it, on synth, installation. Guitar, IMHO, only in the lamp)

The picture is small, nothing can be made out on the diagram
Now I will check this news.
Then we'll discuss in the chat.
Guys, here's the Beringer B215D (d - digital, digital), picking a couple of months ago, a completely professional machine.
Thanks to the site I found out that pensioners added a pension from the 1st of NG.
good goodgood
3GD-38E


And on this I did my first home-made combinator.
3GD-32 is in the highest class radio Leningrad 006, regularly found on classified sites.
2822, when the bridge is turned on, this din shakes normally, but I still couldn’t find the normal D classes, as R555 said they have very large distortions. At least low power, for portable systems. PAM8403 bullshit full.
Assembled according to the VRL scheme
To help the radio amateur magazine, then it was considered good to buy from us yahoo boss
I remember about the D class, but it has terrible distortions.
And the frequency is up to 5.
......
Yeah, find him. More or less replacement 3GD-38E, according to the new 5GDSH - ***

And 2822, IMHO, is rather weak, you need something of the D class.
He had an engraving on the front panel, it seems the guys worked at the factory.
But the boards on this amplifier were hand-drawn.
I was presented with an improvised Marshall amp, it worked, but I burned it.
Well, what to take from a kid, then he studied in grade 5.
plugs on the cables of most electric guitars


Yes, not the majority, but all. They put it on Soviet DIN5, but even those perverts who prefer to play it now have long been remade into jacks.

In general, I wildly apologize, but canine crap, I say as a guitarist. Once upon a time a very long time ago the idea of ​​making a minicombic marshal portable was sunk into my soul:



I was stupid and naive then, and thought that if it was a marshall, then it was definitely cool. In general, I got a KIA6213 chip somewhere, assembled it, stuck a guitar and ... so this circuit is lying around somewhere. In short, if someone wants to make a really normal pocket gun cheap and cheerful, then the algorithm of actions is this:
- Assemble a normal amp, in which the SOI is not ten, damn it, percent. For example, on 2822 in the DIP16 package
- Take a normal broadband. For example 3GD-32 (not to be confused with consumer-friendly 3GDSH-32)
- To collect the normal effect with a wide range of adjustment, not bad BLUESBREAKER, Lionsound, Leo spreads the scheme of previous versions in the public domain.
- Assemble a speaker simulator to emulate a guitar speaker (it is built-in in the Lyonsound).

And then something more or less acceptable will come out. And this is pampering.
It is necessary to show the craps, they abandon these of their Fender.

And I will establish a serial production of this device, in! xaxa
Yeah, wrap the wires without soldering - high class! nea
