Still googlin'
I found some 50v 2200's in the UK
2200uF/50v Silmics
You could parallel these for almost 4700 uF
Good luck
Since my last post, I DID actually call every sales/distributor listed at elna-america in Texas and New Mexico, the ones that haven't disappeared (one), showed no ROA's or ROS's of any value in their "extensive inventory". So I called Elna direct (several times), got voicemail on their main line!! I did speak to a real person once, but she transferred me somewhere, and it was voicemail! Nothing against voicemail, I used to work in that field for almost 20 yrs., but it seems these people do not return calls.
So I am going to keep hounding them, and try to play dumb or pitiful, according to PinkFloyd, he got a free bag from them!!
If I end up getting a line on quantities of Elna's, I will post. I am looking for 1000uF 25v min., 35 would be better, and some 4700uF 25v min, but I have just about decided that I will leave my 4700uF Panasonic FC's as the initial filter caps, and try to get some 1000's for the reservoir, I have some Wima 1uF's for bypass.
Hell, I may just save up for some BG's, I have been having quite a time reading the BG threads over at diyaudio!!
