Coming back out? I'm still here!!

I'll be here until Friday. Staying in San Jose at the double tree..

There is a " thread " so complete concerning the MS250 and MS275?

Have you pics concerning the modification with the RTV?

Suggestions to change the OP for a system SQ...

Unfortunately 1moreamp doesn't post here anymore. You can find him at motion-syndicate.com however

Hello is it necessary to take 5 watt metal film resistors or can i take normal sand block ones for my M44/M50/M100 etc...
I can't find any on digikey.(metal film)

damn.......bringing back an old thread....

I'm sure someone here can help you find the metal film resistors....

Im sorry but in can't find any here in Belgium.

The only i found are these ones,
http://search.digikey.com/scripts/dksea ... CB591JB-ND

Will they work.

just last week i did my 44
and ended up using these...
http://search.digikey.com/scripts/DkSea ... 91W-3BK-ND
i was under same impression as C expressed he was from his crib notes earlier in the thread... , where i thought they were 2w's in there OEM, so i bumped it to 3watts... geese I hope that's okay? i mean given that i guess that they are actually 5 watters in there?
Is that what has been discovered or learned or remembered???

I have benched it, powered up and light sat on green all day today-
doesnt take away from output work needed to be done on the left rear channel- but so far appears to be all good.

I found these ones,

They are 5 Watts will these work.

you have to get 1000 qty at a time though
I'll take/count me in for 4 of them- 10 if it helps

that kinda sucks!
maybe call and ask for sample
sometimes that works

mudder · Post by **mudder** » Tue Dec 01, 2009 11:25 am

Shit man 1000 pc.

mudder · Post by **mudder** » Tue Dec 01, 2009 11:28 am

Ok i'm gonna try something else.
The have wire wounded resistors will they work.

Post by **mhyde71** » Tue Dec 01, 2009 11:37 am

not sure check with eric b4 going with somethign he would be good to bounce that off of- or maybe someone else round these parts-
me? I dunno i would check w/ eric

I have used wirewound for the regulated supply resistors with great luck. Would not put them in any signal path though.

mudder · Post by **mudder** » Wed Dec 02, 2009 8:43 am

So no go with the wirewound resitors.
What are the best resitors i can use in my PG M100/M44/M50 etc. amp.
I whant to change the 2 smal caps and the 5 watt resitor in all my amps.

Post by **mhyde71** » Wed Dec 02, 2009 9:20 am

think like Eric just stated above-
okay for power supply function but not signal so you would be okay
those 5w resitors are power supply related, not signal- i believe so anyways

mudder · Post by **mudder** » Wed Dec 02, 2009 10:19 am

Ok that's good news.

Im gonna order a few on the Mouser website.

could you share the link you are looking at on mouser?
I might wanna grab a couple few too

Here's the link to the resitor page from Mouser, you just need to select the resistor you want.

Well I have a question about the 91 ohm 5w resistor. Im recapping a m44, m50, ms250, zx500 the 91 ohm goes in the m44 but I too have had problems finding this resistor so I was wanting to know if I could use 2 180 ohm 3w paralell would that make them a 6w combined at 90 ohms?

The old resistor got cooked pretty bad and burned the board some or I would just reuse it.
