There are also quite simple in term of number of components.&lt;p&gt;However, there are dangerous, with 400&amp;#x2F;500V DC for the tubes. Definitely not something you should try without being extremely cautious and without previous experience.&lt;p&gt;On the topic of music hardware, another fun thing to build is effect pedals, these are much much safer, and permit to gain valuable experience with a soldering iron.&lt;p&gt;There are also a few kits available out there, either for effect pedals and tube amps.&lt;p&gt;For people in Europe, I can recommend &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.musikding.de&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.musikding.de&lt;/a&gt;&lt;p&gt;* Tube amps: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.musikding.de&amp;#x2F;guitar-amp-kit-tube-amp-kit-valve-guitar-kit&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.musikding.de&amp;#x2F;guitar-amp-kit-tube-amp-kit-valve-g...&lt;/a&gt; (I&amp;#x27;ve built the A15 kit in the past, the components are a bit cheap, specially the power transformer, but it sounds quite nice, and makes for a great 15 Watts dual channels amp).&lt;p&gt;* They also sell a lot of pedal kits: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.musikding.de&amp;#x2F;guitar-effect-kits&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.musikding.de&amp;#x2F;guitar-effect-kits&lt;/a&gt;&lt;p&gt;They also sell parts (specially those a bit harder to find at a good price like footswitches, sockets, a wide variety of knobs etc).&lt;p&gt;Another shop I can recommend for components: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.banzaimusic.com&amp;#x2F;home.php&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.banzaimusic.com&amp;#x2F;home.php&lt;/a&gt;</text><parent_chain><item><author>kpgraham</author><text>I&amp;#x27;ve built a half dozen Fender Bassmans and a few Fender Super amps over the years. I thought the article would be about this kind of amp building, but evidently not many hacker news readers play blues harp through a tube amp.&lt;p&gt;Low tech tube amps are quite easy to build, although they cost a few hundred because the transformers, chassis and tubes can be pricey and the cabs and speakers aren&amp;#x27;t cheap. The results are great, though, and I&amp;#x27;d say go for it if you are thinking about trying.&lt;p&gt;Get everything you need from Tubes and More dot com or eBay.</text></item></parent_chain></comment><story><title>DIY Amps: A Roadmap for Beginners (2017)</title><url>https://audioprimate.blog/2017/06/17/diy-a-roadmap-for-beginners/</url></story>

For people that are just starting out those cmoy style projects are awesome. btw there is also 1W guitar amp in style of cmoy.</text><parent_chain><item><author>kpgraham</author><text>I&amp;#x27;ve built a half dozen Fender Bassmans and a few Fender Super amps over the years.
