Hi Everyone. I have browsed the forums from time to time but finally registered, yah!
I found a couple of fusible resistors on my old Harmon Kardon AVR30 receiver, blown. They are 560ohms 1/2 watts, green color. I'm having a hard time sourcing this value. Neither mouser or digikey has anything. Mouser did have some 560R fusibles at 1/4 watts but that means I'll have to rig up 4 in series/parallel which will not be pretty, and since these 2 blown resistors are side/side, that means stuffing 8 resistors where 2 used to be. I thought about using two 1.2k in series, above and below the board but apparently, 1.2k isn't even a value anyone produces.
I think I read at one time that metal film resistors might work to replace fusibles but if that were the case, then why would metal film fusibles even be offered in a separate line. Anyone know a source for 560R 1/2 watt fusibles or have any thoughts about this? I'm afraid of using non-fusibles since they blew before and the last thing I want is my house to go up in flames.
Thanks in advance.
Norm.
