Hello everyone!
I received this amp, but lacks all fet the power supply, and all of the audio output stage.
Corresponding to the power supply, I have it clear, are HUF75344, but the audio output not know your references ...
Any ideas?
There schema?

I have repaired many of these series amps with using IRFP064N in the power supply using 47 ohm gates with no issues. I have never put them in a T40001bd however, I have used them in T10001bd T20001bd T30001bd
I don't work on these but there have been instances where one or more of the voltage regulators for the rail voltage have failed. When you power up the board, make sure that the rail voltage doesn't exceed the working voltage of the rail caps.
Okay, Perry, I'll remember.
I have already replaced some resistance, and drivers that were in disrepair.
I checked the power supply, only connecting the positive remote, and every gate of the fet pins, a form of perfect square wave is observed.
I am waiting twenty fet's ....

30 units of the one pictured? There are many different MESHA insulators in a single amp of that size.
No, sorry seankane, I was wrong, not 30.
Need, 5 units of housing groups of four FETs (5083-D) and 9 units of housing twos FETs (5084-D)
you got it?

Perry, the insulator was extracted from a motherboard of a new amplifier, and desoldering FETs curiously has remained in that state ..
It can be stannous sulfate?
It can be stannous sulfate?
Yes, I did, I pulled transistors for use in another amplifier.
I heated the back with a mini-torch to remove the fets.

Sorry for the questions...
I looked up stannous sulfate but don't understand it's relevance here.
Did the insulators show signs of corrosion before being removed?

Do not worry, Perry, I will try to explain as best as possible.
The insulator, before removing the FETs, strange signs appeared, at first glance ...
I have four isolators from a P2002, which I bought for cutting a seller of his country, Perry, that seller, just sent me the complete motherboard, but not available sink or chassis amplifier (only motherboard)
I think this seller available many more units like the aforementioned, unaware that the place had stored ...
