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.

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. 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. 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.
