Who has info on R&R caps in ARC D90B amp?

Anyone?

Thank Y'all for your input. They are 470uf/450v. I'm not sure, but I believe the replacements ARC uses are Nichicon GU Series...proabably the LGU2W471MELC. I guess these are mounted on an adapter of sorts.

Nichicon also has a KX Series for specific use in "Audio Equipment" Model LKX2W471MESC45. It has the same 10mm sanp-in lugs.

I'm not sure at this point how to mount them....anyone have some ideas or better yet...a picture, sketch, drawing of how ARC does it?

Hifigeek, I am familiar w/T-Locks, are they locked to the board and soldered or just inserted and soldered?

And, you are correct about the caution on the tracing being fragile...I received this am in failed mode and had to go through it replacing an opamp and some trace came off...using a solder sucker...bad idea - bad idea.

With your experience at recaping the D90B, what other advice could you offer?

THANKS!

I have talked w/ARC - the Cap "Sled" is $500 !!! too much considering the amps value "used" is only $1000 - $1200 and add $490 + shipping both ways for them to do it...I already spent close to $1k retubing with NOS GE 6L6GC's & Amperex "PQ" White Lable 6922's.

With that, the amp runs DEAD QUITE and really sings, said to rival ARC's Reference Series!!! This really is one of their best ever designs.....worth keeping.

Just want to update the caps (before they fail)...I would really like to keep it as a DIY...the (8) Nichicon KX caps are only $68 from Mouser!!

The challenge aside from removing the old ones is to design a nice drop-in replacement (which ARC has). I have developed a few ideas, but it would be nice to see how they do it.

Hifigeek...thanks for the tip on the IC trick....I have the amp's voltages and balance tweeked through out..hope not to have to do the IC again.

Additionally, I 'm thinking of using the copper mesh tape to help suck up the solder during the removal process...your thoughts.

Thanks!

Hello Hifigeek1,

What type of solder sucker would you recommend?

I've used the quick release type and it also sucks the copper tracing off the board.

Also, the small squeeze bulb doesn't work either.

btw, the amp is still going strong, no issues or noise...just sweet music.

Thanks & Regards--
