Rockford Fosgate Punch 200a4

[S Merlington]

This amp is using BUZ272 and BUZ21 as the outputs whats a good replacement for them ??

540 9540

Did they short from 1-3 instead of 2-3?

 

[S Merlington]

They are shorted across all legs ..

On this series of amps the IF3205's will work in the power supply correct??

IF so what gate resistors should i use??

I have 3-4 of theese amps here tha i bought from a friend and all have blown supplys ..

Some have 100 ohm gates some 10 ohms

Also do you have a good part number for the source resistors for the outputs?

 

[Perry Babin]

71-LVR3-0.1 (mouser) should be a good sub.

If the original resistors are 51 ohms or less and none have failed, you can use them. If you have to replace any resistors, I'd suggest using 47 ohm resistors.

The 3205s will work.

Anyone have a high res pic of the area around the 494 and the diode that sits behnd it?

Which components do you need to know what they are?

punch 200a4

Did a search on the punch 200a4 and came up with your thread.
I am currently working on a RF punch 200a4. Was wondering if you had a schematic I could get a copy of. This one I have is missing D8 on the circuit board and I need to find out what it is. Im pretty sure it a rectifier.
Thanks for any information you can give me.

If you have any other questions for this amp, start a new thread.

The original was an MUR1610CT. I generally use the MUR1620CT.

Email me for the diagram.
