I have a counterpoint SA100 audio amplifier that is burning the main line fuse. I’m trying to identify some components. I have a schematic but it’s a very poor one, I don’t think it’s a factory original schematic but one that somebody has drawn up. It seems to be missing some components that are in the unit, such as power switch, the line fuse, one of the audio inputs, etc. Plus it’s in Spanish which makes it more difficult.
Can you identify the components in the picture with the red arrows? I thought they were bridge rectifiers at first, however I think the bridge rectifiers are on the main board and not on the chassis.
The wires running to them come from the power transformer.
Thanks a million everyone.

I do not know if this was you were looking for, and just a wild guess from me.

No sir it isn’t, but thank you. The unit I have is an hybrid tube and mosfet audio amplifier
They are in fact bridges. The transformer windings feed into them (see wire colors and chart on the label) and the outputs go to the caps then off to the board. Easy enough to disconnect and test. Make sure the caps are discharged and note the wire positions before removing. You can also disconnect the board side and test with just the transformer and rectifiers to see if it is in the supply or on the board.
Radios + Tubes + Scopes + Cars= Nothing better!
As “RadTekMan” has said they are the 2 main (power) bridge rectifiers. And following the chart label found on top of the transformer you can easily identify what goes where by looking at the colour-coded wires. I have not seen the schematic but as for the other square-looking bridge rectifier you’ve seen on the board, that must be an additional low-voltage power supply needed for the lower voltage stages such as the ICs, etc. 
PS: your problem is likely to have something to do with the final Power Mos-Fets. After verifying the integrity of the power supply (first). I would (next) check them all. One by one.
I have seen those form factors in the AN/WSC-3 radio in the past. The one I saw was a bridge rectifier that was used to create 28 volts that was used as a sense voltage for the radio. It was also used as an external keyline voltage with specific multiradio racks. Believe it was done as the voltage needed to be tapped off before going to the rest of the power supply in the radio. May not apply in your case, but this is one application of that component body shape 🙂
