Memphis 16-st1000d

Componentr · 9th March 2008, 09:30 PM

Can anyone supply me with a high res picture of the Memphis 16-st1000d board or the value of the R51 resistor?

R51 and R52 are the same (22 ohms). Use flameproof resistors. Values taken from the board shown below.

1/2 watt or 1 watt?

Perry Babin · 9th March 2008, 11:10 PM

Those appear to be similar to the resistors made by Phoenix Passive that are rated at twice the wattage of resistors of the same size. Measure the resistors in your amp and look up the size in the following datasheet to determine the wattage. It appears to be a 1w.

Hey i burned the resistors in this 16-st1000d at r41-r45 and need to make sure the mosfet numbers are correct. CAn anyone help? the amp has 4 irfz44n and 4 irf3205

I do not remember which transistors the amp uses, but all 8 should be the same.

I kmow I am new, but that is a 500d bord, there is only a 60 amp fused power supply. the other 1000mcd used 80amp. I would check that before replacing 4 irfz44n and 4 irf3205 trans, as the value may not be the same. If the sub is Ok, it is ussuualy the driver cicuit that burns up. you can allways call 1-800-467-2400,Fulmer Co. go to tech and just ask them if they can help you out, you could have been a long time customer and just need some help.

All 8 of the power supply FETs should be 3205s. The gate resistors are 22 ohms.

Generally, at least one of the driver transistors (KTA1266 - Q15 and Q16?) on the driver board fails. Check the drive signal and the driver transistors before reinstalling the 3205s.

Just making sure that someone hasn't replaced the FETS with the wrong ones then had me fix it. and the resistors are toast. no way to measure or read. at r41-r44 but i can read r46-r48. there are 4 3205s with 23 ohm resistors and then there were 4 irfz44n's with burnt resistors.

someone threw those 44s in there to see if it was gonna make it work, and it didnt.
