WD Pre III
I have just recommenced building the Pre (thanks Richard, and especial thanks to Matthew at WD for help with parts). I have a stock of Nichicon caps, which I like, but don't have the 470uF that I need for valve decouplers. Seems hard to find the Nichicons at that value. Can anyone suggest suitable alternatives?
Thanks David

Re: WD Pre III
I've used Elna SILMIC ll several times, they seem pretty decent to me.
HiFi Collective list 470u in 7 voltages from 6.3v to 63v Phil.

Re: WD Pre III
Matthew should have them, or maybe upgrade ones from the XL version, can't remember what they were.
Circuit says 470uF 16V. Cathode voltages are 4V and 9V so 16V should be ok, or 25V has lower esr and is only a little longer. I use Panasonic FC from RS, https://uk.rs-online.com/web/p/alumi...itors/3150467/ https://uk.rs-online.com/web/p/alumi...itors/3150574/
