Hi, I’m looking to replace all the SMDs in my Krell amplifier. Can anyone recommend good replacements? I’ve attached a photograph of the board. Just not sure what the best brand is for these and which part number. I assume the are 47uf, 35v SMDs rated to 105C. Same question applies to the other SMDs. Thank you all so much in advance. ![932cf05c-4d35-4b81-bf7a-8685d930559b](https://global.discourse-cdn.com/digikey/original/3X/f/b/fb102b0ca8d83d1b45ab83be57d7017edfb3d433.jpeg) ![f06e0305-54ed-4f90-adcc-b642a5a502e4](https://global.discourse-cdn.com/digikey/original/3X/7/d/7d0a2fff01f358c48fb521dc52dea241ed2702ed.jpeg) ---

I see 2 that are the 47uf, 35V on your board. If you are looking for a replacement, we need to know the dimensions of the plastic base at the bottom. That ensures they will fit properly on the board. ---

Thank you, i’ll measure straight away. The others - 6v 47uf and 25v 10uf - are they polarised at all ? I don’t see a black mark at all indicating the negative side ? ---

> [@dsbhachu123](#): > > I’m looking to replace all the SMDs FYI - SMD = surface mount device What you are asking about are aluminum electrolytic capacitors, and in the pics they look like through hole mount not surface mount. ---

Hi Paul, Apologies I should have been more specific - I wanted a replacement for the SMD capacitors rather than other through hole ones. Best wishes
