A new way to restore smoothing capacitors

[Yorkie]

I've just taken delivery from Farnell of some of the newly stocked miniature Rubycon BXW series of miniature caps, which are ideal for stuffing multi-section can type electrolytic caps.

At first sight they look puny and not really up to the task, but they do have a high ripple rating, beyond what is needed for typical domestic valve radios. Those in the attached picture from left to right in the 'front row' are 15uF, 22uF, 33uF and 47uF. The three between the two cans are 18uF and give an indication of their small size. The small can on the left is a (NOS) 3-section 16uF which is 25mm diam x 45mm tall (1" x 1.75" in 'old money). The yellow can on the right is a (NOS) 2 section 16uF which is 35mm diam x 50mm tall. (1.5" x 2") - same size as the smoothing/reservoir cap in the DAC90A etc. As can be seen, even in the smaller can, three caps would just fit side by side, 'triangular fashion'.

I don't want to spark off a pointless debate about the merits or otherwise of stuffing old electrolytics and I know that not everyone may want to go to that trouble, especially in a commonplace set of little value, but instead, may prefer to simply disconnect the old cap and fit new ones beneath the chassis. But for anyone who does wish to stuff caps to preserve the originality of appearance of the set, these particular ones lend themselves to that role. (Those in the picture ore all 450V WKNG). As to price, they're not expensive - all fifteen came to £24.41 inc VAT and free delivery - about £1.63 each on average.

Hope that's of interest.

Thanks to 'Refugee' for bringing these dinky little caps to our attention!
