Hello, does anyone know which chips are on the card, they got erased, thanks

Board

 

[Perry Babin]

Maybe a DLI4060 for the large IC. The photos of the board that I have for that amp don't have the smaller ICs. The attached photo could possibly show the other IC.

yes perry, how can I know if it has that? use transistors channel n and p for each channel use 1 and 1

 

[Perry Babin]

how can I know if it has that?

^^ Has what? Be specific.

 

[streetilegalbass]

with 2 outputs on it turns on normal and everything and if I put the other 2 on one side it has consumption and the 6v -6 +6 regulators are hot but the channels work well

 

[Perry Babin]

Consumption? Current?

If so, 1 amp, 5 amps, 50 amps?

Remember, we're working 100% blind except for the information you provide.

 

[streetilegalbass]

15A approximately, in standby and when increasing volume consumes more and at a certain volume it distorts but only if you have the 2-channel transistors channel p and n on one side without those 15A disappear and stays at 1 maximum in stan by

I got this photo from a video on YouTube you can see the ic but I search the internet and I can't find anything like it the ic133 and 313 are not seen by the sponge

 

[Perry Babin]

I don't think that those ICs are present on that board. It's like the board below with a different driver IC. The Powerbass xa1500 used a mix of driver ICs like those.

 

[streetilegalbass]

Thaks for you help Perry

 

[streetilegalbass]

you will have idea what are the chips of this other driver card i think it has some ic with logic gate, but i am not sure it has mpsfet on output 6 irf640n

 

[Perry Babin]

Is that from the same amp?

Do you know that it is a driver board?

 

[streetilegalbass]

It is from another amplifier a rock series 1000.1D Mexican brand

 

[Perry Babin]

I can't help on that but please don't mix repairs in the same thread. Start a new thread. Include the make/model in the subject field.

 

[streetilegalbass]

ok i will start another thread thaks
