I like to explain and teach how to build and how to fix electrical devices. I also like to 3D-print stuff whenever there is a spot for that.
How to make guitar amp from ANY tape recorder or cassette player (really easy)
This video shows how to make guitar amplifier from ANY tape recorder or ANY cassette player. Literally every device can be modified this way, it doesn't matter if it's old or new.
Original tape head, which reads the tape, is simply replaced with guitar input, so device is "thinking" that it's playing the tape, but actually it's playing a signal from the electric guitar. Rest of the device stays untouched, so this modification is easy to undo, if needed. With mono-device, it's easier with just 2 wires at the tape head, but with stereo there will be 3 or 4, but after all it's just about finding the ground and finding the positive signal..

This video shows how to diagnose and fix common problem of an old CD player. Common thing is that hatch (sled) is not moving in correctly. Other common thing is that CD is not lifted from the sled, so it will not rotate and play at all. Cleaning and lubricating all moving parts and changing the drive belt is usually enough to make things work again. Problems are usually caused by old loosened b...

This video is simple and general instruction how to change led chip (LED COB) to the flood light. This repair instruction can be used in almost any size and type of flood lights, no matter if there is one or more chips. Typically led drivers (power supplies) are not the problem with these led flood lights, but it's wise to diagnose those before changing the led chip. Led chip can be different s...

Prison tech :-)
A Reel to Reel tape recorder was my first Guitar "Amp". I didn't have to take it apart though, I was able to plug right into the quarter inch jack on the front, and put it in record mode, and crank it
Well..., yes and no...., I have used in the studio an exact tape recorder like this, as an amp..., but the easy and more suitable way is to plug the guitar in the mic, or line input, and then use it to get the tubes in the amp section of this tandberg really working....
Yeah, in this case the record-mode wasn't working, so here's alternative way😃
*_"But will it djent or chug?"_* 🤔
Doesn't really beat a Mesa/Boogie Dual Rectifier, Marshall JCM800 or Fender Twin Reverb but it is interesting
I guess any "real" guitar amplifier or efect pedal is better than this😃 but interesting alternative use of electronic device
As a reel-to-reel user I am not happy with this destruction of a nice tape recorder. Apart from that the amplifier in a tape recorder is really not that suited as a guitar amplifier, because it is not linear. To compensate for the inductance in the magnetic head and the tape itself, and to reduce tape hiss as much as possible, the tone balance is altered both when recording and playing, and it also depends on the tape speed, which is the reason the sound of your guitar will probably change if you turn the speed controller to 3 3/4 instead of 1 7/8.
I'm also reel-to-reel user and also repair these devices frequently. This specific unit was moisture damaged, so wood case is ruined, inner metal parts rusted and rubber parts and friction pads were worn out, so no point to repair anymore. I will collect some spare parts to save other devices in the future, and decided to create something new and cool from this one.
@@Riihimasa That comforting to hear 🙂
I am more interested on the guitar
CNC-machined out of two acrylic plate and bolted together, electronics fitted inside without holes to the outside surfaces. Also remote controlled RGB-leds inside😃
@@Riihimasa Is that high quality tone acryilic?
Some generic and cheapest clear acrylic from the local hardwarestore😃
super low volume
Thanks for telling me, I can adjust volume levels with next videos.
What?
System all ok but sound is not coming
Usually it's good way to start by crossing off simple things: test if something works, just the radio, or just the cd, or just the cassette. Then test with different cd, different speakers etc. after that next thing is to look inside and check that all cables are in place. Also visual inspection gives a lot of information, one expanded capasitor may cause whole device to be mute.. good luck finding the problem of your device.
Très puissant appareil ,comment avoir faire pour avoir encore ?
I'm sorry, I don't understand the question..?
please don't think of me as rude but I could only manage the first 55 secs of the video due to the intense hand shaking of the camera.
Yeah, main point is give tips for repairs, but maybe I should get some kind of camera stand..
