    PSU 0-60Volts

    Bikerman, Dear neighbour, here you can buy the Mosfets in Denmark ;D. http://www.elfa.se/elfa/produkter/en/2458.htm They are not very expensive; they are cheaper than the 9540. I think you can get away with 8 of them if well cooled. 8) Ante ::)

    PSU 0-60Volts

    Vainajala, I am sure it will work with 45Volts if slightly modified. And the Mosfets must not be attached to the pcb or what do you think? Ante ::)

    Bench Test Equipment

    Kevin, It sure is a good help for determining pulses and such. I think $150 is OK for this scope. How hot is very hot and what is the source of the heat (power supply)? The GND switch just grounds the input as far as I know. It looks good but what

    Who is using the oldest computer?

    wasssup, This is a bit more effective than a fan! http://www.tomshardware.com/cpu/20031230/ Now tell me you have 4.16G with a fan! ;D ;D ;D Ante ::)

    0-30 Vdc Stabilized Power Supply

    Kain, I have never disassembled a toroid ;D and often there is an airgap on the old types that is enough to put on a few turns. The wire needed for this kind of low current is only a very thin insulated one and not many turns are required. The PCB transformers that are moulded are of curse out...

    0-30 Vdc Stabilized Power Supply

    Dazza, I usually put on some turns of wire on top of the transformers winding to create a separate supply (or two). This solution takes some experimentation and it is not all transformers that have room for this extra winding. Ante ::)
