Hold the cap between your fingers making sure not to touch either lead. Your body acts as an antenna to pick up RFI noise which is transmitted through your fingers to the cap. For example, tube amp enthusiasts will love browsing the many popular vacuum tubes available, including the Tung-Sol 12AX7 Tube: ideal for guitarists who want high gain and terrific linearity. Or how about the Groove Tubes Gold Series G-12AX7-C: the warm, fat, old-school tone of this tube is perfect for guitarists who are fans of the blues and.

3. Stress Relief. Where parts are mounted between turrets it is mandatory to put a stress relief bend in at least one lead (Figure 8-5). Before adding power to a new amp be sure and verify the safety ground connection. Plug a guitar cable into an input jack and check that you have continuity (meter "beep") between the guitar cable's sleeve (the part that isn't the tip) and the amp's power cord ground prong.

Lets start by looking at the simple standard tube amplification circuit that you will see again and again as you study tube amp schematics This inexpensive Tube Amplifier kit has been available for a number of years now and makes for a nice little tube amp. Don't let the inexpensive price tag fool you, as this tube amp can go head to head with amps that cost $800. With its very modest price tag, this kit is an affordable step into the wonderful world of vacuum tube audio Remember to leave the turret top holes available for wires that run to tubes, controls and jacks. You can connect lead wires to the bottom turret hole for a cleaner look but be sure and use a circuit board bottom cover which will hold leads in place. With no bottom cover your leads may fall out when you solder components to the top of the turret.

Doug Hoffman is also one of my go-to sites for tube amp parts. He also has pre-made amp circuit boards and he'll do custom boards too. Install pots, fuse, power & standby switches, transformers and choke in the chassis and do as much wiring on these as you can before you mount the circuit board because it can get crowded in the chassis, especially Fender tweed chassis. It's a good idea to use washers on your output transformer and choke bolts to reinforce their mounting flanges. Their weight can cause their mount holes to rip if the amp is dropped. Don't forget to do the heater wires before you install the circuit board (unless doing flying heaters). A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s. Valve amplifiers can be used for applications such as guitar amplifiers, satellite transponders such as.

Opening a tube amp kit and seeing all those little parts can be overwhelming so I recommend you do an inventory of the big parts like transformers, chassis, switches, tube sockets, etc., then immediately begin assembling the circuit board. Getting all those little resistors and caps in place on the board will make your amp project seem much more manageable and it will help you identify missing components or circuit board layout problems. It sucks to come close to completing an amp and then realize you're short a capacitor and have to wait for delivery.

The exception to the rule above is for components you know will have to be replaced in the future, like electrolytic filter capacitors, put their leads in the turret top hole to make unsoldering them easier. If you think you may mod your amp then place components you think you may swap out with their leads in the top turret holes to make replacement easier. In some cases external capacitors can be mounted off board to supplement or replace the on board capacitors. As with any tube amplifier the capacitors and the transformers are the most critical components in the amplifier. This is because all capacitors are far from being electrically perfect

  1.         Tubes 9 & 10 are also in parallel so they are wired out-of-phase.
  2. Install the power transformer into the chassis. Use grommets in the chassis holes where wires pass through.
  3. al can reduce 120Hz hum and buzz.
  4. Start your build with the circuit board itself, either eyelet, turret, B9A development board or even perf board. If you are making your own circuit boards I recommend you use #3 Eyelets or Turrets designed for 1/8" (0.125") thick circuit board. Making your own eyelet or turret board is surprisingly easy with the right board making tools. Doug Hoffman sells a variety of tube amp circuit boards using either eyelets or turrets and you can buy them empty or with components soldered in. He also has an online program for creating a circuit board design then he'll make it for you. You can also submit a DIYLC file to Hoffman to create a custom circuit board.
  5. I designed the RR763 BLACKVIBE amp (see layout and schematic below) for builders who don't want to deal with the complexity of the AB763 circuit's reverb, tremolo and dual channels but still want its authentic tone.
  6. Power tubes wired in parallel should have their heaters wired out-of-phase for hum reduction. We do this because if the same heater hum gets into two parallel tubes the hum is additive--it gets louder. If we wire them out of phase the hum will be subtractive and cancel out. To wire out-of-phase one heater wire would be connected to pin 2 on one power tube and pin 7 on the other power tube.

Install the components to populate the board but don't start soldering until the components and lead wires are all in place and you're sure they are placed correctly. If you have access to an oscilloscope you can easily determine the outside foil lead and orient your non-polarized capacitors for least noise.

If you plan to do Fender blackface style flying heater wires then save the heater wiring for last. I recommend you connect the 6.3V filament heater wires from the power transformer directly to the first power tube, then split two wires from there: a thin set of wires to the pilot light and one to the next tube. Try to keep the tightly twisted heater wires down against the chassis floor to reduce noise and hum (unless you're using flying heater wires) and keep track of phase.

Placing your non-polarized capacitors with their outer foil connected to ground or the circuit's lowest impedance can reduce the amount of RFI (radio frequency interference) they pick up and prevent capacitive coupling between components and nearby wires. If you have an oscilloscope it takes just a few seconds to determine which lead is the outer foil on non-polarized caps (caps with no + or - end markings). Some caps come marked with the supposed outer foil end but many times the marking is wrong so I recommend testing all your caps before installation. Doing this really can reduce RFI, environmental noise such as LED lights and reduce capacitive coupling in an amplifier circuit.

There's no better guitar amp to start with than the Fender 5F1 Champ. It has only 26 components but sounds fantastic. The circuit is so simple I use it in my How Tube Amps Work webpage. It is a single-ended amp with one power tube. Keep this in mind when choosing your first build, anyone can piece together a complex amp. The problem is as complexity increases the more likely you are to make an assembly mistake and troubleshooting a complex amp can be extremely difficult for a beginner. That's why I recommend the simple 5F1 Champ. 1. Parallel Mounting. Parts shall be mounted parallel to, and in contact with, their mounting surface. Slight angularity is permissible. With the circuit board fully populated but not soldered it's a good time to post pics of the circuit board (front and back) on a guitar amp forum for others to review. I like the TDPRI Shock Brothers DIY Amps forum (I'm robrob). Be sure and take a photo of the back side of the board so you can review it in case you have to troubleshoot the amp at startup--you don't want to have to remove the circuit board to verify its backside wiring and solder joints.

Install jacks, pots, fuse, power, standby and ground switches and as much of their wiring as possible. The VTA M-125 mono-tube power amplifiers offer the ultimate in channel separation (and yes, it IS audible) along with features including pentode-triode modes, 4 and 8-ohm output taps, and the ability to tube roll.

  6. One of the more difficult aspects of building tube amp guitars is figuring out all the different types of capacitors used in them. For classic amps I like to use Mallory 150 polyester film capacitors (now made by Cornell Dubilier CDE) for caps in the signal path. Another set of popular signal caps are the Sprague 225P series "Orange Drop" polyester film caps which are also now made by CDE. The Mallory 150 and 225P Orange Drop caps are very close in tone and construction to the "mustard" caps made in the 1950's and '60s. For cathode bypass caps these are my favorites. For small, Marshall sized 0.47 and 0.68uF cathode bypass caps I like these Vishay & Kemet 0.47uF tantalum and 0.68uF tantalum caps. For very small value caps used as bright caps and tone stack treble caps I like to use silver mica caps. For power supply filter caps I'm a fan of F&T caps.

I like to use carbon film resistors in place of carbon composition resistors these days because carbon film create much less resistor "hiss" (shot noise). I recommend metal film resistors for the input (V1 grid leak) and V1 grid stopper resistors for minimal resistor hiss injection into the first gain stage.

You need a good quality soldering iron with a clean, pre-tinned tip to successfully solder eyelets and turrets. Frequent tip steam cleanings using a damp sponge will make soldering easy and keep your solder joints looking good. For high quality solder joints you must use rosin flux on the eyelet/turret and the component leads because it cleans and removes oxidation so the solder can adhere for a good, long term connection. I just dab a little flux on the joint using a thin artist paint brush or you can use a refillable flux pen. You want good solder joints because chasing a cold solder joint can be a colossal pain in the butt. I'm a fan of the $99 Hakko FX888D soldering iron. Weller soldering irons are also well liked.
