Just playing around with the new RF amp and my old PPI amps, I decided to take the covers off and show why I say they don't build them like they used to. Keep in mind the specs:
RF T600-4
4 x 100w rms @ 4 ohms
4 x 150w rms @ 2 ohms
2 x 300w rms bridged @ 4 ohms
PPI PC2400
2 x 100w rms @ 4 ohms
2 x 200w rms @ 2 ohms
1 x 400w rms bridged @ 4 ohms
PPI PC2600
2 x 150w rms @ 4 ohms
2 x 300w rms @ 2 ohms
1 x 600w rms bridged @ 4 ohms
Now for the pics of the guts.
First up, the PC2400 vs the RF T600-4. Note the size difference and circuits despite the RF being rated for 50% more power:
Next is the PC2600 vs the RF. These amps are rated for the same total power. Just look at the circuits on this bad boy
