So, the three color transistors on my neck board were very hot.. so I upgraded the heat sinks..

But now I notice that the three big 2.7kohm r528,529,530 resistors hooked up to them are SUPER hot..

Is this safe/normal? I had intended on ordering new color transistors.. but there was a mixup in the order.. and now i've gotta wait a bit longer..

thanks
 
Yeah, it's pretty common, it was kind of a design flaw that was in the U2000/U5000 and carried over to the 7400/7500. They get so hot sometimes the resistors or transistors will unsolder themselves and fall off the neckboard. No shit.
