    Tangent Lupus Amp and Preamp.

    I have found that the amp is around 100 watts a channel 8 ohms, and that they were made in the early 80s. That's about all I can find.

    I never even went out to the garage tonight to work on it. To hot. Working in the heat all day wore me out.

    Toshiba SA7100 so hot it melted veneer on top

    I don’t have the board out. Hard to get a pic. I think I found the resistors you are talking about though. Should there be one for each transistor. Is it the white square ones in the center of pic by the big black cap

    Toshiba SA7100 so hot it melted veneer on top

    Ok. I cleaned the ends of fuses. Getting the same readings as before. However I think my meter is off by a bit. If I’m correct when you touch leads together you should get 0. Mine shows .4 , I put pic of meter to,show what settings I have it to to make sure I’m measuring it right.

    Thanks avionic. My meter isn’t the greatest, when I touch the leads together I get 0.4, when I check the fuses I get 1.5 on one of them and 0.4 on the other one.

    Toshiba SA7100 so hot it melted veneer on top

    That was my next move, when I find some time. Remove the heat sink and boards and check the new transistors closer. I’m not sure if the heat sink was discoloured from this repair or from before the transistors were replaced.
