Best place to get resistors?

I need to replace the fuse resistors (R17 and R20) on my G-9000DB driver boards. From what I can tell, 1/4 or 1/2 watt metal-film resistors are the best replacements as opposed to getting the regular fuse resistors. Where would be the best place to get them from?

Firstly you need to use 1/4watt, I live in a different country and use local suppliers, but most guys here seem to use mouser I've noticed.....
Good luck.....
 
Thanks kevzep. Which brand did you get through Mouser? It looks like they have about 4 different vendors.

I got mine from a local supplier in New Zealand called Element 14.........but yeah theres a few different makes, I cant remember which ones I got, they were 1% tolerance though, I never go for the cheapest.......
 
Mouser or Digikey
Vishay's & KOA Spear metal film work for me.
 
I don't like the ones from Digikey. They are so small they look stupid next to the other parts on the board. Get them from mcm or parts express.

Or carbon film Takman http://www.partsconnexion.com/resistors_takman_rex.html. Those old ones are in the most cases carbon film.

The 1/4W look stupid but the 1/2W are Ohh-Kay....

Mouser carries KOA Speer Metal Film Resistors for a few cents apiece. Shipping will make the price per resistor outrageous unless you have other goodies to get at the same time. How about a trip to Radio Shack, if they still exist in IL.

TR14, the transistor to the right of the blue one, is not original and probably not the right rating for that application. I would change it to something more robust and with a proper metal tab for heat transfer.

I need to take pictures of the "stupid looking" resistors from Digikey but I don't know what I did with them. I'll look again tomorrow.

These pictures comes from two different amps, the first is a BA-2000 , seconded by a AU-11000A

These transistors looks the same in the two amps.
 
I've never been inside either of those amps but I've also never seen Sansui screw down one of those T0126 case transistors. Also looking at the arrangement of the other transistors I assumed they were pre-drivers so I'd expect to see another B537 in that location. The schematic would list them correctly so if it matches the schematic, no worries.

Pete, If you've never been in either of those units how the hell would you know they aren't original? They are the bias transistors and they are in fact proper and original :D
 
mroboto, the re-cap looks good :thmbsp:

I would also suggest you change the VD1212 diodes (D01~04) on all those driver boards as well.
 
Those UniWatt transistors can be trouble too - had a bunch in my AU-9900 that needed replacing as they had gone very low hfe.

Looks good though :thmbsp:
