Maybe I can help. I'm on his list of ARC service providers....

Thanks guys.

I want to replace the 300uF 450v caps in my D90. I checked with ARC. The original cap is no longer made. They do have a cap kit which includes a cap and an adaptor, but unbelievably expensive. I would like to get Steve's input to see if there is any replacement cap that fits. Any suggestion?

Thanks,

What is the diameter of the old part? Does it have screw terminals?

Off hand this does not sound like it would be all that hard to find something.

I will give you my 2 cents. The problem is that, generally speaking, the twist lock caps that came with the amp, hence the hole pattern on the circuit board, were pretty awful caps. The new caps are much better as they are not twist lock caps but have a small circuit board adapter on each one. In fact you can consider it an upgrade. With those caps, the amp should sound better than when it was new. There are other electrolytic caps that should be replaced in that amp as well due to their age. If you would like to discuss it further you can email me : gary.mf1@gmail.com

It is 35mm. The lead spacing is 10mm. Snap in type. I looked at mouser and digikey. They have caps of the same diameter and spacing, but shorter. There are quite a few. As Hifigeek1 explained the origianl caps are twist lock which I don't quite understand yet. Will have to desolder one out and check.

Anyone has experience or recommendation on the replacement caps?

Thanks,
