i recently priced some of the caps i need for my tube tester and crt tester and they are expensive and not in stock. so i have literally hundreds of electrolytics of all kinds of values all new so i was wondering if anyone knows if i can do the following,for a 450v 50uf i have a 450v 47uf and for a 450v 5uf i have 5- 450v 1uf in paralle and for 250v 20uf i have 2- 250v 10uf in paralle would this be acceptable for use in these testers as replacements. i dont think this cap would be close enough but ill ask you guys ,for a 0.1uf 1000v i have a 5.6nf 2000v metallized cap would this be close enough to use?i dont know how criticle these caps would have to be not to effect performance thanks
