As noted above, when replacing small 50V electrolytics up to 2.2uF I recommend using 63V "PET metallized film" capacitors which come in compact "box shaped" packages. The Sony PVM-1271Q contains large quantities of these 0.47uF, 1uF, and 2.2uF 50V electrolytics. Tiny electrolytics frequently "dry out" and become open circuits because they contain only one drop of electrolyte. PET metallized film capacitors are reasonably affordable and will last longer than electrolytics.
The sweet spot here seemed to be up to 4.7uF, based on size, price, and quantity.
Also, there's no longer any need for the separate bipolar 1uF ones since all the PET film caps are bipolar.
My updated recap list is attached (I added a tolerance column), as well as a screenshot of the Digi-Key prices for them.
Back when I fixed Sony BVM & PVM monitors 4 days out of 5, the very low value electros were pretty much unobtainium, & I routinely replaced them with film caps---with nary a problem.
We used all those monitors "In house", so I would have known if there were any!
As we were part of a large TV network, we pretty much got "champagne service" from Sony on their own special parts, but the low value caps weren't part of that.
Japan seems to have been awash with the low value electrolytics, as they pop up in just about every bit of gear from the 1960's through to the early '90s.
Of course, they are not the only ones with strange electros.
A BW Electrohome came in, with collapsed vertical scan.
The problem was the filter cap on the power supply to the vertical output, which was obtained from the rectified output of an "overwind" on the Horizontal output transformer.
For reasons of their own, the denizens of the "Great White North" used a bipolar electrolytic in this spot, which was "dead as a doornail".
Farnell had some bipolars of what looked like similar characteristics, so I ordered some.
I was surprised at how much smaller they were and marvelling at the onrush of technological progress, fitted one.
On turn on, up came the Electrohome with perfect vertical scans, as I congratulated myself, for all of 10 seconds, till the vertical collapsed again,along with a hissing sound & ominous vapour coming out of the cap.
It seems that the big cap was both bipolar
& low ESR!
I ended up replacing the cap with a "Christmas tree" of "Polyester Greencaps", which did the job without flinching.
Pretty?---No, but functional?,
Yes!
