[QUOTE="Extreme1ont, post: 7634285, member: 639396"] Anyone know where i can find schematics for a punch 125.2 amp. I think its been worked on before and there is alot of different parts in it, i have now found all of them i need to order, but there is alot of mixed up parts and not sure if thats how it should be. want to find schematics on it and double check what transistors and fets its supposed to have.. for future reference... cross ref with mouser parts.. numbered like this.. looking at top of board. power side.....................speaker output side.. 1 2 3 4..........................5 6 7 8 ............................................. 9 10 11 12.....................13 14 15 16 1 50N06V = 526-NTE2395 2 50NO6V = 526-NTE2395 3 U1620R KAK 4 LM317T = 511-LM317T 5 IRF540-F ????????? 6 IRF540-F ????????? 7 IRF9540 = 844-IRF9540PBF 8 IRF9540 = 844-IRF9540PBF 9 50N06V =526-NTE2395 10 50N06V = 526-NTE2395 11 U1620 AKA 12 LM337SP = 511-LM337SP 13 IRF540 = 844-IRF540PBF 14 IRF540 = 844-IRF540PBF 15 IRF9540 = 844-IRF9540PBF 16 IRF9540 = 844-IRF9540PBF Ok so now the confusing part... # 5-6 should be the same part as 13-14 but the 5-6 part has a F on the end.. i know this might sound the same.. but most parts i found that have 1 single different number on the end means a lot... different polarity ect.. Parts 3-11 and not the same.. took me 2 days searching to find a similar part if you notice #3 U1620R KAK and #11 U1620 AKA.. kak and aka are the diode polarity of the chip. do not confuse these as the same thing.. I found these as replacement.. NTE6240 & NTE6244 NTE6240– Positive Center–Tap NTE6244– Negative Center–Tap im not sure what one is what #3 or #11 im so confused at this point lolz but i know you need the 2 different parts either way.. #5-6 are IRF540F and #13-14 dont have F on the end.. i think the "F" ones are a few more amps but just looking at data sheets now its only 2 AMP different so probably not an issue to use the same ones.. Does anyone have one of these old punch 125.2 they can pull the bottom cover and tell me what chips are in it.. #4 and #12 i would think should be the same part but in mine they are different.. all of them in series are different then the opposite side, thats why i think this has been worked on before and someone just slapped whatever in it and maybe why its not working now [/QUOTE]
