............. As the constructor of the supply shown on his web-side I thank you for your interest. Unfortunately the construction is not intended for production, and I / we cannot take on the task of producing a unit for you. I can furnish you with all the information necessary for the electronic part of the supply however, drawings of the chassis works I have not, unfortunately. I will charge you nothing for the schematics, printed board and parts layout. The schematics are drawn in a tool named S-plan, the board and layout in a tool named S-print. I attatch to this mail a reader program for each. If you have the possibitlity to produce printed boards, you can make a 'film' for this purpose by printing the layout onto a transparent film (laser printer). Please note that all parts are obtained through a local (European) dealer. Parts names/designations may differ if you buy them in the US. If in doubt, you should consult ELFA A/S: http://www.elfa.se All parts in the parts list will have an ELFA-number. Observe that the pads which seem not to be connected (appearing red in the viewer) are actually connected to a ground plane covering the whole of the component side. I have used small copper or brass bushings for the holes through these pads. For all the other holes the ground plane copper just around the hole must be removed. (Using a drill bit for example) If you can obtain/produce 2-layer throug-plated print boards, this type of problem is of course not present. The following components are mounted on the solder side: D1, D2, D8, L2, L3, L5, L6. L1, L4 and L7 are carrying some current, use toroidal coils as physically large as the layout permits, allowing for the stated inductance. (Not critical) Unfortunately, the transformer T1 is not well documented. (Constructed and mounted, then forgotten) But I seem to recall this much: The two secondary vindings each giving 67,5 volts are put on the bobin first, each is 40 turns. Wind the two windings with paralel wires. Wire size is not critical, the bobin should end up mostly filled when all windings are completed. Next, the 6V output and the feedback windings, each 4 turns are twisted before being wound on the bobin. Use at least 0,5 mm wire, preferably litz wire. The primary is put on lastly, 7 turns. Use a large size wire, preferably a litz wire. Spread out the turns of the primary and the two 6 volts windings (intertwined) as evenly as possible in one layer. Observe the polarity of each winding! You may find it neccessary to experiment a bit to obtain the right voltages. Good luck with the project! If you feel that questions arise during construction, do not hesitate to contact me. It seems that you have another option, Army Radio Sales co. (UK) offers a french made supply on their web site: http://www.armyradio.com/arsc/customer/home.php?cat=71 They charge $74,- for a unit working from a 24V battery/supply. ------------------------------------------ I hope the above info will be useful to you. As you can see, I have attached the component list. I also have the printed circuit board layout ready,. but not incorporated in this mail. The layout is done using the program S-print. To get a print-out you have to use either S-print or VIEWLAYOUT.EXE (which is free). Please inform me if you are interested in this wiever program and the lay-out. (if your firewall (if you have one) repels .exe files in a mail, I could rename the extention) Best regards, Jan - LA4JH
