Massive P1500.1

The power supply drivers are marked

M6
L6

And some other transistors marked G1

Does anyone know what the part number is for these ?

 

[Perry Babin]

The driver transistors aren't critical. See attached.

The other is an MMBT5551.

You said the drivers weren’t critical .

Can I use the MMBTA56/06 as the drivers in the power supply ?

 

[Perry Babin]

Yes. That's what I used in virtually every power supply that used SOT-23 transistors.

 

[caraudioguy2100]

Anyone have a picture of the audio driver board ?
Or can tell me what transistor goes here it looks like it blew apart at one point .

 

[Perry Babin]

In that location, I used an MMBTA06 but I think the original may have been an MMBT4401 (2x).

 

[caraudioguy2100]

Is that a driver ic on e audio board or an opamp

If it’s a driver ic do you happen to know the part number ?

 

[Perry Babin]

If you're asking me, you'll have to re-phrase the question, with specifics.

 

[caraudioguy2100]

Is the 14 pin ic on the audio aboard a driver ic? And if so do you happen to know the part number ?

 

[Perry Babin]

It's a 74hc00. The MM74HC00M is what I used.
