There are 7 electrolytic caps in my 8060A, which matches the parts list. All the silkscreen polarities seem to be correct, though I can't see the polarity or silkscreen for C16, the 1uF tant without sucking it off the board.
The build date for my meter is going to be late 1999 or early 2000 judging by the IC date codes, with the date of the PDF 2000 or later.

In 8060A, C19 is 47uF 10V capacitor, used with U2 SC77174P, Flukes custom made TRMS converter. If your meter has Fluke's TRMS converter then C19's placement is at the lower right side of the LS1, Piezo Transducer or adjacent to the pin 1 of U2. And if your meter has AD636 TRMS converter mounted on a daughter board, C19 is not required. But if you still want to know its position, it is under the lower edge of that daughter board.

Ah, mine has the AD636 daughter board. Thankyou for explaining that.

Make me want to buy a 8060a to go with my Simpson 260.

You'll find them on the 'Bay for about $100 from Israel.  My personal record is 150 SEK, for one that turned out to be in excellent shape. Before that I'd bought one from USA for about $75, which was OK. But not fantastic.

A re-cap of course is important. All info is here and in the blog post from Mr Modemhead, which is found both upthread and as a courtesy here.
