memphis 1500d

[timwebb]

ok i got another 1500d i just rebuild the power supply and these two resistors started smoking.

[Perry Babin]

Those probably feed the voltage regulators. Are the regulators or any of the capacitors connected to the regulators shorted?

[timwebb]

ok i changed all the capacitors and the resistors still over heat.

[Perry Babin]

Do they overheat if you remove the regulators from the circuit?

[timwebb]

no they stay cool.

[Perry Babin]

With the regulators out of the circuit, do you read anything near 0 ohms when you measure the resistance from the ground pad for the regulator (pin 2 for the 78xx and pin 1 for the 79xx) to either of the other pads?

[timwebb]

yes it reads 0 ohms

[Perry Babin]

Which one?

Have you disconnected the capacitor across the shorted terminals to see if it's shorted?

[timwebb]

i got my hands on one of these.anyone ever use one?

I have that Z meter to it works grate cause you can be sure of the cap under its rated voltage (up to 500 volts hell ya ) and the inductor meter as well for custom audio passive crossovers inductors I have alot of copper alot haha and the price on inductors WOW Ill make my own !! How much did you paid for it ? Oh I also have the owners manual and circut manual Sencore LC53 in pdf file if you need it i can email it to you .
