Help please. Trying to fix JL500/1

[Ljrsf49er]

Need help identifying some of the components I need to replace. First time I’m working on an amp and a jl at that. Any advice is greatly appreciated!

 

[Perry Babin]

Which components?

 

[Ljrsf49er]

I don’t know how to post pictures. It keeps bringing me to a new page

I hope the pics made it this time

There are 8 power supply FETs. The originals are likely IRFZ44s. Use the IRF3205 as a replacement. The gate resistors are 47 ohms. The size is 1206. The drivers (at least one) appears to have failed. The 2SB1260 and the 2SD1898 are viable substitutes.

Do NOT buy parts from ebay. Mouser and Digikey are good sources if you're in the US.

What about the other side. Do you think any of those need to be replaced by looking a

I took a couple extra pics. Can you tell me what u600 is by chance?

 

[Ljrsf49er]

Also which ones the drivers. Very sorry for asking dumb questions but I am very new to this and the power mosfets are irfz44r if that makes any difference

I’m really sorry for wasting so much of your time but I’m looking for these parts and they’re giving me those models with the mfg part number 2SB1260T100R. Is that the same one?

 

[Perry Babin]

Yes. 2SB1260 is the part number. T100 indicates that it's on a reel of tape (not bulk or in a tube), R is the DC current gain designation. The datasheet tells you all of this.

Not sure if Ljrsf49er got the power supply rebuilt in the 500/1, but if you need some help, Sam (aka Barevids) has some videos of repairing them, found this one where he is rebuilding the power supply. He has a few others.

There are 8 Fets in the supply, that 9th one is not a FET, its the rectifier, just FYI
