Wow nice job again sir what took you so long to be on CZcams great to see more and more people doing these types of work not many of us are around keep up the good work sir nuff respect 👍 👍 🙏 🙏
Nice Jesse. I thought for sure you lost a rectifier when I saw that jumper. These SFBs like to cook rectifiers. Oh and thank you for the shout out! If you ever need help I am available any time.
Not a problem! Thank you as well!
What are the part numbers for all the transistors
@@69malvarez There are quite a few different markings from the manufacturer so it depends on which ones you are after. I don't have one in for comparison but the 4115 and the CSD18502 are common.

Hey I have a sundown audio Amp that needs One of those things that you're adding to that album, but I don't know how to get 1. Can you help me out?sfb 3000 sundown audio
I have blown voltage regulator it say h1 on the power supply side it’s like 4 on that side
Jesse I have a 1000d that the power inputs need to be replaced.
Is that t something that you can help with?
I have a sfb 3500d it plays when every now and then after a little drive. Can you tell me whats going on with it plz
So, I just add a spot of paste on the back of each transistor tab. About the size of a grain of rice. I do this for a few reasons. First, the paste was designed as a glaze that just fills in minor imperfections in the mating surfaces. It's not suppose to be a transfer buffer for the entire surface. That will actually impact thermal coupling in a negative way. A small amount will do as it will spread hydraulically once clamped. Speaking of that, if you add too much the clamp pressure will loosen as it spreads hydraulically over time. Third, It's an unnecessary waste of product. Fourth, the next tech that has to open that amp won't be mother f**king you for the mess...
I upgraded to using a paint brush for most of the repairs based on recommendations. Thank you.
I have a sundown sfb 1000d ,the Protect light stays on and power light comes on and off,what do you think is the issue and which transistors should I replace and where can I purchase them ,I would really appreciate the information ,thank you...
are the 4115 you replaced the correct Fets on the outputs? are they not getting hot without load? because i did not see in your video, checking the temperature of the output FETS.
Can you please tell
Me what output transistors are used in this amp? They are just labeled B1 I have 2 amps with the same issue. I removed the good transistors from 1 to fix the other.
