    Universal Laborator System!

    Hi Shahriar If you mean the intercoms i talked about, there isn't anything digital there, they come in the 1960:ies or so, and used AM in the beginning, and later FM, because of much noice and interference. And they used freqs around 100-200 Khz! They where fully analog! No, even 100 Khz works...

    Transformer Power Rating

    Hi Run the fan at full speed all the time instead, i suppose it is a fan from a computer. Audioguru is much better in calculating this kind of things. We can ask him. Hey Audioguru, what do you think? //Staigen

    Transformer Power Rating

    Hi there I checked the voltage of the BDW 83/84 transistors and the C stands for 100V collector voltage and the D stands for 120V collector voltage! This means that either the C or the D verson can be used in this cirquit! Mickey, the tranny shall be a 2X28V/8A type, not a 2X23 Volt type...

    Universal Laborator System!

    Hi Shahriar Isn't this similar to the intercom system that used mains as transmission line? They usally used 100 Khz, 120 Khz and 140 Khz as comunication frequency. I reparied one such intercom once. //Staigen

    Power Supply.

    Hi Is the tranny rated for 18 Volts CT @ 45 Amps or 36 Volts CT @ 45 Amps? ??? Of course it is a 36 Volts CT tranny, but the schematic dont says that! ;D Hey, thats a 1620 VA tranny, a real big one! ;D ;D //Staigen
