Was a waste of 35 mins timberland. Booooooooooo.

Mantaf

Try to be quicker getting to the point. Your losing me

Do you know how to fix a weak buzzer? My 7-4612B doesn’t have a very loud buzzer like all the other GE clocks from 1987-93.

Signal tracer time buddy. My guitar input board wite connection was kjust barely disconnected on the actual board i barely touched the connection and boom instantly the amp fixed.

Check out

Hey bud, did you ever figure this one out? Only curious because I have the exact same guitar amp and same exact problem. However, my amplifiers against the rear heat sink are blown.

Too bad it doesn’t come with a couple of meters so that you can keep track of the current and voltage

Please do yourself a favor. Chuck the "lead Free" solder. It doesn't flow well, it doesn't stick well, and causes a lot of problems down the road. Use 60/40 solder. If you want, use a face mask N-95.

It's so increible immoral to make such a device disposable :S

Hey Mr. Tinman Technologist, can you tell whether the Guitar Input on the Amp is a stereo jack socket or not? I. e. can you go in with stereo effects or not?

Good video! I tamed the overly sensitive volume pot on my hotrod Deville by exchanging the 12AX7 preamp tube in V1 for a 12AT7 ..Fender mfg really should address this issue.

Your information is very good,❤ I work with machines that use several encoders, and I loved your teaching, 🇧🇷😉👍congratulations on the video! 👏👏👏👏👏👏 "@arduinomaquinas" thanks you ! ( subscribed).

you don't need to change any tubes, you just need to put a better pot for volume..... as John Boley said, the audio taper pot. It is a 5.00 part and it's easy to change out....done

Do u know how to fix the screen when it gos very dim

Great video. Should of made more :)

Good job, but you also could've tried a 500k variable resistor for less volume, also according to Psionic amp, there are places on the board that over heat also some of Fender amps have issues and can be modify and you should asked other techs what they might actually be? I have one here (on lone from a good freind) and one thing I learned is this Deluxe Mod 3 uses a Celestion 80 and is total wrong for this amp. A 30watt to 50watts would sound a lot better then what it maybe using now. I borrowed his amp to try my 2 JBL custom cabinets I built. My little junior uses a 12"inch JBL and a 2-way JBL crossover with a Sansui tweeter closed system no ports. It's like day and night. My cabinet is beautiful and it does make the Fender Rock with my D123e. I also have (from the same peron) a Fender Viborluxe from the 1970s with new caps and resistors and it's original D123F JBL 15". It last belong to a steel guitarist that passed away and his nephew inherited his musical collection like my favorite Uncle died and he bonded with and asked to help make a sound documentation of my 50 watt Bugera T-50 over the 40 watt Fender and show off my Homemade custom Joe Junior over little Junior? It will be filmed.

It's the volume pot that needs changing really, they used a linear pot instead of a audio pot. Easy fix.

*Hi! I, too, recently disassembled an e-cigarette, and even used its battery for other purposes. Stop by and visit)*

THAT'S ENGINEERING! omg that was the best part of this video!

An easier way is to replace the pre amp tube /valve with an ecc82 or 12au7 It gives you full clean volume control .

Searching for months I need your help I can't find a small micro controller that charge and discharge a battery with 8 second time limit connected to an led and it sense's low pressure to close the circuit to discharge and it's 3mm in length and only has a resistor connected to it (s0890 Ap) that's what I can read

What happens if you go beyond the 0.9 and 2.1? like for example you input a full 5v cycle instead of max 2.1ms? Smoke? or Will the servo just do nothing? I ask cause I want to try and mechanically control a cnc spindle using a sg90 and a 3d print to attach to a potentiometer that controls the spindle RPM on a GRBL v1.1 with a 0ms to full cycle range.

That’s an awful lot of complaining over a $60 kit that actually works. The complaints over the bent case are legit, but come on. How complex did you expect this to be?

Thank you. I was hoping to see how the output signal to the dc motor changes with angle error and pwm input.

2 is not loud on these amps. Maybe don't use a 40 watt tube amp to practice with in your living room....

They could have done much better with the TO-220 regulators @9:09. They could have designed it so the regulators mount vertically on the PCB and by moving the board toward the rear of the chassis, mounted to the case with insulators (they require that anyway on the heatsink. If you have to mount a TO-220 like that I recommend soldering the wire parallel with the lead, don't wrap it around the lead, and then heat shrink each lead of the device and wire connection completely to prevent accidental shorting.

Regardless of what you do, these amps are loud. They are not for the bedroom. 😜

Congratulations! Very clarifying video! I am looking for a circuit to be connected to a radio control instead of a servo to enable and disable the power of a camera (900mv x 11v). Do you know any product, or would you indicate a diagram for assembling a circuit?

7805 IC requires minimum 6.5 volts to give 5 volt output + 0.7v shunt resistor 🤔

What soldering station works well. Thanks.

I have one on my desk and it looks identical to yours. Even has the same 7-4634. Very cool units but I have never been inside mine. Seeing those capacitors worries me that they might go out at some point. That would not be good

I have a very similar one. Mine is Model No. 7-4630C. However, I am trying to use it as a radio for DRIVE-IN theaters. Any advice on how to repair the Batttery function for it?

What kind of Pots did you replace the bad ones with. I can't find them on Digi Key?

Have you seen this man?

JJ 6V6S Power tubes decrease the volume considerably but still loud enough to cut through a band mix

Just change the first pre amp tube (sorry can’t remember what the new tube is called) and that’s it. Rolls off 20% of the volume. Some people also use a volume pedal in the effects loop. This is way to much crap to do when u can achieve what you want with a single tube swap. EDIT: tube is 12AT7. Just replace the first pre amp tube

Tda ? Number serie??

That's the EXACT same problem mine has. Want to come fix it? Lol I've had that clock since 1983 or 84. The hour and minute buttons are starting to stick now too. If I knew how to solder, I'd totally take it apart and work on it. I'm afraid I'd break it beyond repair. Lol But it's so cool to that see others still have the same clock after all these years. I've seen this model in a couple of tv shows and movies too. It's a great clock! 😁

1 meg audio taper pot fixes the problem.

Use interrupts on 2 and 3 and then you don't use processing power. When interrupt then do A>B or B>A.......

I not understand 0.9&2.1ms what say, but i really like your video👍

I had never used leaded solder. Learned with 97/3 tin lead. It didnt seem to bad. Then i ran out and had some good 60/40 sitting in a drawer so i got it out and tried tinning some wire and it blew my mind. Its so easy to work with and it wets and reflows so easy. I think ill be using lead from now on

you don't build anything you just assemble

Change the junk IRC caps and stand the power resistors off the PCB

I agree, it is a loud amp. Had mine for 15 years now. What puzzles me is why you don't have a dB meter to show the viewers the actual sound pressure numbers. I would guess at 1 meter from the center of the speaker, the sound pressure would read, 120 to 130 dBs.

What you hear is the heat protection switching the chip on and off. Put a good heat sink on the chip and bingo it wil work. This is a common Line6 overheating problem of the modchip and on the voltage stabilizers. Many amps are thrown away because they can fix it. Such a waste of good material.

hahaha ... you did that about six years ago ... would love to see what you think today on the same "Disposable e-cigarette teardown" ... with best wishes... hahaha

Nice job to help me get started. A little foggy about continuous rotation versus just changing position and stopping, but this gets me to where I can hook one up. Apparently, Uno can do PWM out of the box so the adafruit part he used is not needed unless you have more than six servos to control. Although it is nice, the Adafruit board is a little overpriced for what it would do for most applications

I dont think for 60 Bucks that its a bad power supply. Its your basic LM317 Supply and for a beginner, I think its perfect. It's more than adequate to power your small projects
