Is that farenheit?

Yep

 

[laatsch55]

Next time, shine it on the black part of the transistor..

 

[derek92994]

Roger that, do you want me to retest and do you want Faren or celcius?

 

[laatsch55]

Ok....let's check low voltage test points on both channels. Negative to backplane ground, positive to test points..

No, Fahrenheit from here on though when we do..

104.7 and 104.6 using ground and tp1 b+ on backplane

 

[laatsch55]

Low voltage on the driver board, +15, -15 middle of the board and left edge..

 

[derek92994]

Left 15.06+ 15.66-
Right 15.02+ 15.57-

 

[laatsch55]

DC offset, both channels...Neg to backplane ground, pos to backplane out...

 

[derek92994]

Left 0.4
Right 1.1
200m dc scale on dmm

 

[laatsch55]

Bias Ok?

 

[derek92994]

Bias 355 and 354

 

[laatsch55]

Ok, now lets check driver board input voltages and compare right to left...Negative to backplane ground, positive to 3 thru 8 on each side, write down the values..

 

[derek92994]

So you are talking about the green connector 3r-8r etc?

 

[laatsch55]

Yep, the screw on the Phoenix connectors..

 

[derek92994]

Exclude pnpr one between 5r and 6r?

 

[laatsch55]

No....ccheck em all except input from RCA jacks and the last 3 on the left side of each connector block....those are ground and plus and minus.....well fuck, check those too..
