By Rob Robinette Have comments or corrections? Email rob at robinette at comcast dot net For a first amplifier build you should consider a kit because it can be difficult to source all the correct components and shipping charges from multiple vendors can add up. Building a kit is also a great way to boost your understanding of electronic theory and tube amplification. I recommend Mojotone and BootHillRecommended Resistor & Capacitor TypesComponent Placement and SolderingI like to use carbon film resistors in classic circuits in place of carbon composition these days because carbon film create much less resistor "hiss" (shot noise). They are a nice compromise between classic carbon composition and ultra quiet metal film resistors. If you want your circuit board to look 1950s and '60s period correct then you will need to use carbon composition resistors. I recommend metal film resistors for the input (V1 grid leak) and V1 grid stopper resistors for minimal resistor hiss injection into See more on robrobinetteExplore furtherFender Champ 5F1 Guitar Amp DIY BuilddiyaudioblogGuitar tube amplifier parts and accessories - Watts Tube AudiotubeamplifierpartsConstruction of a Guitar Amplifier - ProjectsallaboutcircuitsWhy Buy a Single Ended Tube Amplifier When You can Build build an amp rob robinettes car and tube ampbrighthubengineeringGuide to Vacuum Tube Amplifier Design - Vacuum Tube build an amp rob robinettes car and tube ampvtadiyRecommended to you based on what's popular Amp Startup - Rob Robinette's Car and Tube Amp Website Plug in the Amp.If your amp has a solid state rectifier and no standby switch proceed to Step 4, otherwise turn the Turn the Standby Switch On.
