Phoenix Gold Phorum

Hey guys does anyone have a digikey part number for replacement resistors on the backside of the m50? I know they are 2watt 10ohm.

It's a 20ohm resistor....perhaps its a different revision but that looks red to me, if its brown black black then its a 10ohm but if its red black black then its a 20ohm.

Its red black black gold

Its a 20ohm then....what rev is it?

Its a rev A

I thought it was a 10ohm

Tricky do u kniw a part number off digi for it

Are you talking about these...



I was pretty sure they were Brown Black Black Gold, which is 10 ohms.

Thanks eric and yes sir those exact ones

Eric u know any replacement part numbers on digi or mouser

I would recommend the TO220 package...its an overkill because those are around 25-30watts and will require to be mounted to the heat sink (which there is room you'll just have to drill and tap then mount the to220 resistors. They aren't cheap either, around 5-6 each but you won't ever have to worry about those heating up on you or heat dissaption.


Yes they are 10ohm...so perhaps yours are 20ohms because they are rev.A, so pretty sure the later versions had the 10ohm resistors.

What u mean TO220 package

Could u elaborate a lil more in lamen terms lol

And is that something that i can search on either supplier

Also what diff does the 10ohm and 20ohm do in either application

those are 10ohm/2w metalfilm 5% resistors..............

Eric D has shown all of us how and what to do.........

What causes these resistors to do this guys....

Bridging w too low of a load?

If you power the amp on with no speakers connected and no RCAs, then leave it on for a year sitting there, the resistors will still do this. They don't overheat from abuse, it is just a less than optimal part of the product design.

So i got the right resistors orders thanks again eric and.paul
