Tantalum Capacitor xLOTS... Anyone seen something like this?

Yup, resistors, each colour has its own number, first two bands are single numbers, third band is the amount of zeros after it, last band, its the metallic one is the accuracy.

That older stuff often has Tantis though. Get aquaintted with the pics as they often look like the plain Ali can capactors, or the Ali film ones.
Normally they are marked with the positive pole (rather than the negative pole like most other caps) often they have two rolled grooves in one end and often a weird centre pole/wire.
Remove the whole thing, unsolder the wires, don't clip them off. Often the whole wire leg is Tanti too.
If it isn't, well it just ups the weight anyway. The buyers know this, its taken into account as its worth the loss to gain the extra % of Tanti wire.

After edit.
I have been looking closer at CRT tv boards, they often have one red 'match head' tanti.
Sometimes several.
But older stuff is where you find the 'Tanti cans'. Newer stuff the 'Yellow block' Tantis.
Car electronics the various sized. 'Paint drop' Tantis.
In general...

But, unsolder the legged Tantis, if you can't at the time, chip/cut around them on the board and save the board bit that's soldered to the Tanti and unsolder it later.
