Re: Nickel plated heat sinks

I've not done any extensive research to determine if there are other factors, but literally thousands of hardware items and fasteners are nickel plated. Pretty much any screw you purchase that is bright and shiny silver, but still magnetic, is a nickel plated fastener. As far as I know, there is no ...

Re: PG Tantrum 500.2 amps - Failed output FETs

I'm sorry for the delay, I thought I answered this when you first asked, but I must not have submitted the reply. I've never seen a tantrum with anything but irf540's. I'm not sure where you found the other info but I've repaired dozens of tantrums, they all use Irf540 outputs. First of all, there i...

Re: Zx350 OVL then Steady Green after cap repair

Overload led for a few seconds and then green led is normal startup behavior. The o/l led is lit while the poweramp is muted during power up. This is to keep any pops or thumps from hitting the speakers. The amp can easily overload a small DC power supply. You can run a more stout supply and either ...

Re: Sapphire XS4600 Amplifier no power

BTW, I don't believe I've ever worked on a xs4300, so it's possible I'm incorrect about those diodes not being stock. They're should be at least 4 more mosfets somewhere for the other channels, and they may actually be there under the crossover board. Normally in the tantrum amps, and I've fixed ple...

You are missing the point. Switching power supplies in automotive amplifiers are basically the same across virtually every make model and power, only the scale changes.

I just went back and looked at your pictures more closely and I noticed that 3 of the channels have diodes fitted in place of outputs. Are these the mosfets you replaced, or did you replace the power supply mosfets that we told you were going to need replaced? If you didn't replace the power supply ...

Re: XS2300 Blk Repair

Most times devices in the do-41 package that are not diodes are RTDs. Pg did not often use them in their designs, but in the xs and tantrum amps they used a 10k NTC RTD as part of the bias control circuitry. I cannot tell from the picture if these are RTDs, but their circuit designation will be &quo...
