MTX Thunder 81001

I just got this amp in for repair tonight. Looks like its gonna be a fun one.
This thing must have gotten real hot inside it melted the bar that holds the fets in place.

Do NOT power this amp up without having everything clamped down. The regulators (especially the positive regulator) can fail within seconds which can cause components to fail throughout the amp.

MTX 81001 DAMAGED HELP..!!!

GREETINGS,

I have damaged my MTX 81 001, missing pieces in the power and want to help me with the values​​, these are:
Q210 and Q221.

thank you very much dear friends.

 

[Perry Babin]

Q221 is a PZTA06. I don't see a transistor with a circuit board designation of Q210. MTX will give you the part number if you email them.

This transistor is next to Q221, and is the same size, and is connected to the base with R252 = 100 ohm

thank you for your valuable information

That one is also a PZTA06. The attached photo is from a 1501 but the layout in that area should be the same.
