This will be my first build and I want to know I have great customer service behind me. Maybe my next build I'll buy from somewhere else. |

I just finished building the Champ today. To my amazement, it actually works.
I would not say it was an easy build (for me). That chassis get real small and some of the connections were hard to make. I made a few mistakes along the way and had to redo a couple of solder joints. I spent 3 days putting it together. I don't know if I would want to do it again, but it was a good learning experience. |

That's when I learned that you don't solder everything together till it's laid out! So I did that, I laid everything out made sure it was good and then soldered it only to find that two of the spots I totally overlooked and didn't solder. Hence the importance of good mechanical connection. It still worked but I noticed I skipped those points when soldering. I also soldered one electrolytic cap in backwards and had to order a new one I'd love to see pics of your Champ. |

I'm a bit embarrassed about how sloppy it is. Hey, it was my first attempt and at least it works. I'm 65 and my old eyes aren't what they used to be. I had a hard time reading some of the resistors.
I'm glad I built the Champ. I learned a lot and if there will be another one, I'm sure I will do a better job. Last edited by Bluside; 01-01-2021 at 06:23 AM. |

Some great posts on here, especially WRT safety advice. I'm in the UK and built an 18 Watt from an https://www.ampmaker.com PP-18 kit a few years ago. I'm still using the amp as my main electric amp both in the home studio and live, absolutely love it to bits. I was a novice amp builder but electrically competent and it took me around 10-12 hours.
I would reenforce the safety aspects, valve amps have 350VDC+ floating around inside, even after they are switched off, so make, and use a capacitor discharge device. I used an Autotransformer to bring up voltages slowly but the light bulb limiter will do a similar job. The smaller Ampmaker kits, up to the 18 Watt (currently the slightly enhanced P-1800) come with well written documentation and step by step instructions, including safely testing everything stage by stage, my build worked first time. Prices across the range are good and the owner is a good guy and very willing to help if you have issues. One last thing, if you embark on an amp build, treat yourself to a temperature controlled soldering station/iron before you start, it'll make your life much easier. Oh and one more last thing, I used lead/tin solder, I've heard that lead free is harder to work with but as I'm still using my stock of the old stuff I haven't had to find out yet. #Blueside, you Champ looks great... #redir, Looking forward to your build thread

Friendly historical note: original Champs have a 25uf/25V cap in parallel with the resistor at the far right edge of the board. Fender's documentation from the fifties is missing it, as is Mojotone's by extension. The amp will function just fine without it, but will not achieve the same levels of overdrive and gain as an original.

Sure do. The vintage one is via the internet (I lost a whole lot of pictures during a phone upgrade a few years back where I had gotten firsthand pics) and the modern board is where I picked up a build someone else started and got frustrated and had me finish it for him. On the vintage amp, it's the huge cap on the far right end.
