Fender Champ Amplifier Build Part 3 of 3 Don't Miss the Ending

[@DennisMurphey]

Great video series, I too build an AMP with lots of help. I had a old signal tracer that was not working. A friend told me he could help me convert it to 5 watt Fender Amp design. He did the schematics and I built the circuits. Not a kit with a PC Board but from scratch free hand like. Oh it was a challenge and several times the volt testing proved I had messed up. But we finally got it debugged and I use it today. The built in 4 inch speaker is great for practice in my office while I have a switch for an external speaker a 10 inch Fender in a Stand Alone cabinet. So my little Signal Tracer Sits on top. We even got the Magic Green Eye to pulse on Power out When you hit the Bass notes. I think these kits are wonderful to show folks the complexity yet the simplistic nature of old Tube technology. Now I want to see the Theremin video. Wonder if you could route that output to the Fender input for an Amplified output!!!!!!

[@DennisMurphey]

I meant to say my Amp is point to point. It looks like a rats nest and being was challenging. But fun and we got it.

What a mighty sound reactor! And what a maestro you are on the Fender. A very beautiful year ending project. Stay blessed brother!

[@moebiusfan9545]

Really cool build! Appreciate you taking time for it.

[@frankowalker4662]

Nice kit and it sounds great.

[@nickrobinson6434]

Just built one of these, it sounds amazing! Sad the volume pot only goes to 10 though.

[@bblod4896]

Sounds great Mr. Guitar man. Glad the higher voltage didn't make the tubes into a flash lamp. Have many great years enjoying your new amp, don't forget, sign and date the inside. Happy New Year Paul. ☮️✌️

[@electroKrunch]

Thanks for the series, man! Great little amp huh? I had a silver face Fender Bronco years ago that was a similar circuit, loved that thing for recording!

[@petercornell2002]

Nice series, thanks Paul. Sounds fantastic! When I build any project, I actually measure each component before inserting it into the PCB. Saved my bacon a few times.... Peter

[@learnelectronics]

Kinda wish I had done that. Hopefully it was a learning experience

[@mikehensley78]

thats a beautiful amp! i didnt know you could get amp kits like that! nice.

[@paulperano9236]

Bit worried the power cable maybe getting to close to potentially very hot valves. Perhaps a cable clamp along the side ? Was wondering if some of the 'signal' wires going under the heater wires maybe causing some of the hum. Looking good though Paul and a fun project to ride along with. Thanks

[@gammaseven]

Hi there. Great Fender amp video. By the way how did you change the wrong resistors. Did you remove the whole pcb or clip the wrong ones on the component side and attach new ones. Well done

[@ivovass195]

Very nice build, well done

[@Electronics_123_]

Excellent work

[@learnelectronics]

Thanks for the visit

[@Johadart]

Hey buddy, try and get yourself some hemostats, they’ll help you, instead of pliers.. great series build mate, I like the tunes at the end.. 🤙🏼🇦🇺

[@TheTrueVoiceOfReason]

Happy Post-Holidays Paul. Just a quick question, what size is the driver they sent with the kit? If you mentioned it, I didn't catch it, and I didn't see a parts listing on the website. Thank you for all you do to get others interested in electronics. Here's to a lot more years of this fun. Cheers!

Re volume numbers ,Why not scrub off the numbers11and(spinal tap) 12? Also the artificial centre tap resistors , are you sure you used correct value.,? I often see 100 -200 ohm used

[@learnelectronics]

They too were wrong, but that was my bad.

[@andrewwilson6240]

Interesting to hear the 60Hz hum when the disconnected multimeter lead was acting as an aerial. I am so familiar with 50Hz, and this does sound noticeable different

[@electronic7979]

👍

[@hans-peterhoefer1598]

Very good video series. But unbeatable was the moment when you stuck your finger into the running amp to show where you changed the resistors. Maybe you should watch the part with the life-threatening voltages inside an amp again yourself;-)

[@learnelectronics]

One hand only. Not grounded. Been doing this stuff for over 30 years.

[@hans-peterhoefer1598]

@@learnelectronics Be honest, at that moment you didn't think about whether you were grounded or not, you just stuck your hand in to show something. In retrospective analysis, it may not have been suicidal, but it would probably be better if you didn't get into that habit in the first place. And it's not a good example, is it?

[@jeffryallen4511]

@@hans-peterhoefer1598 he was using a plastic pen to show the resistors - chill out,

[@snowdiddley4634]

Sounds 👍 great

[@toddzino58]

Hopefully tubedepot was notified they shipped the wrong resistors?

[@robertwebb5586]

Use Uncle Rob's Flux On The Tube Terminals.........)

[@daytonpyro]

i have this old RS receiver,. DX 160. would you like to recap and tune it up? i could drop it off for you

[@learnelectronics]

No. I don't mess with RF stuff.

[@TRONMAGNUM2099]

Excellent work. I don't know anything about guitar amps, but to me, it sounds pretty good. Maybe you can release a vid of you playing something like Cliffs of Dover for us.

[@learnelectronics]

If I could play Cliffs of Dover, I would. Eric Johnson is a bit beyond my skills.

[@sumduma55]

I was thinking the same thing. You only need it to go to 11.

[@toddzino58]

I was thinking it too!!!

[@andrewwilson6240]

Me too "This one goes to 12"!

[@tenlittleindians]

That's definitely not a "Made in China" cabinet. The person that covered yours paid attention to details. All the stripes on the individual pieces of fabric were carefully cut and positioned to line up with one another. That's rare to see these days. The only thing that would have made it better would be if it had a hand written piece of tape installed with the name of the worker that covered it. All old Fender amplifiers sported a builders hand written name tag. Next I'd like to mention the chrome plating. There's a reason we don't have chrome bumpers on our cars like we did in the 70's and it's called the E.P.A.. I had some Harley parts chromed in the early 70's. I had to take the parts across the river to Illinois as the E.P.A.. had already made it hard on the plating shops in Iowa to dispose of their toxic plating solutions. It must be extremely hard to find a shop to do it today and probably expensive because of the waste restrictions. Although it has a circuit board I think they kit designer did an excellent job. The tubes are not mounted in a position to cook the circuit board over time and it does keep everything neat and tidy. Very much like the kind of quality the old Heathkit company put into their kits.

[@learnelectronics]

It's handmade in Tennessee.

@@learnelectronics Times have changed. I bought a 180 watt Musicman amp with the twin 12" speakers for half what you paid for this kit. In the 70's those Musicman amps were considered the next evolution of the Fender twin reverb. I dragged it up and down stairs for years. I was a lot younger and stronger and still complained everytime I had to transport that heavy pig. The kids can have them. I'm content with my smaller amps at home and I'd never go back to dragging my heavy combo amps out to gig with anymore. That little amp of yours went up in value as soon as you finished soldering it together. It may have to appreciate in value for a few years to get back the value in labor you had to stick in it but it will get there.
