HI All

Have been working on a TT 961 PS, it blew Q1 2N5301, replaced both pass 
transistors with 2N5686 NPN devices, 300 watt, 60 volt. . Also replaced a 
shorted Q3 2N5087.
.

Back in operation as far correct voltage, but current trip is not right. Very 
little current trips PS output voltage.

Checked all voltages, they look good, .60 ohms gives about 22 amps, will give 
the right current to adjust for proper trip levels.
Also replaced Q5 thinking it my have got stressed as well.

Any Ideas????????
