No MOJO parts were used in the construction of this project i soldered these by soldering from the top and sweated the solder between the pot wafer and circuit board. I tinned the board first before I attached the three control pots. When attaching the footswitch, raise it slightly above the circuit board - do not push it down hard against the board, otherwise you will not get enough thread through the top of the case to attach the mounting nut. The 7915 regulator needs to be raised at approximately 45 degrees to prevent the metal tab from contacting the solder side of the control board - you may have to adjust the 7815 regulator sideways to avoid contact with the solder side of the control board as well. Lightly file and tin the footswitch, before attaching the green board to chassis earth wire. Tube driver pedal kit series#The 10k and 47n series connection is connected to the solder side of the tube socket board. I used 30 amp fusewire for the wires connecting the three boards - note the wire is connected to the solder side of the tube socket board and the component side of the control and driver board. The input and output sockets were purchased from Aron at DIY Stompboxes store - good value for money The long pin wire on the led connects to the vacant pad that connects to the 7815 regulator IC, the other lead connects to the pad which is connected to the 1k5 resistor. The status led is inserted in the top of the case and attached by flying leads through the hole on the circuit main board. Tube driver pedal kit full#I will be posting full details in the next few days - stay tuned The only other piece of equipment you will need is a suitable 16vAC power supply - there are many 16vAC 1.5A types available as burglar alarm supplies - just buy one of these and solder a 2.1mm dc socket on the wires - because it is an AC supply it does not matter which way you connect the wires I may be able to supply board kits on request, but have not worked out prices as yet, because this is a very new project. However, you can build your own if you would like to, because I shall be placing the complete design layout, PCB, chassis, and artwork details exclusively for all registered members of the freestompboxes forum. Tube driver pedal kit plus#I will be building these on a one by one basis as time permits, and the price will be US$330.00 plus postage etc. Very low noise and hum levels, due to the fully regulated bipolar power supply I gave my finished prototype a run, last night at practice, and was complimented on my great guitar sound (not playing ability mind you ). There is only one wire to connect the board to the chassis earth. The three boards are solder pinned togaether and form a very strong structure to hold the tube and controls etc. There are three circuit boards - a mother board that holds the footswitch, input, output and AC power supply sockets a small board to hold the 12AX7 tube and it's passive components, and a board to accomodate the driver dual op amp and three control knobs. Power is from an external 15VAC 0.4A plugpack.Inspired by Dirk Hendrik's Real Tube Screamer pedal project elsewhere in this section, and after reverse engineering the B K Butler Tube Driver, and noting some similarities, i have designed a brand new design for a REAL tube drive pedal, housed in a Hammond (or equivalent NSC) 1590BB case. Mozztronics uses the industry standard 2.1mm socket for the power supply connection. Watch the video here of course watch the whole video, but the TD1 is at 5:57 TD1 was named Gabor’s drive pedal of the year for 2018. Overall Drive Pedal Video from SuperFunAwesomeHappyTimePedal Show TD1 video from the SuperFunAwesomeHappyTimePedal Show Tube driver pedal kit download#Or download the sample from my Dropbox Mozztronics TD-1 GAIN controls the amount of overdrive from a light crunch to a searing screaming overdrive, TONE adjusts the brightness of the signal, VOLUME adjusts the overall output volume of the pedal, and there is a 3 position CONTOUR switch to select between mild / normal / heavy. We here at Mozztronics use the tube where it is meant to be used, in the gain stages, so the drive you hear is tube drive. Some products with tubes use the tube for filtering only, in the “tone control” section of the circuit. This is the Mozztronics take on a pedal with an actual 12AX7 tube inside. Many pedals on the market have the word “tube” in their name, and while these can be quite good, they don’t use a real tube to get “that sound”. Using a 12AX7 tube, and powered from an external 15VAC to 16VAC supply with a 2.1mm plug, this pedal runs the tube in starved plate mode, for that real tube sound.
