Crumar performer capacitor failure

Postby casarete » Tue Apr 28, 2015 11:56 am

Hello everyone,
I have an old Crumar performer that does not work perfectly,
sound ugly and key YES to all octaves sometimes sounds nothing ..
I checked the power section and I noticed that the condesantore Tantalum 2.2 uf 50v broke
sending short also the fuse supply output ..
I turned a little to electronics stores but nothing doing is not ..
with that type and value of the capacitor can I replace it?

You can use any similar value electrolytic, perhaps with higher value capacitance. The capacitor may be a bit larger and need to be mounted with wires, but don't touch any other wires.

Or use a couple of smaller tantalums in parallel to make up the same value or larger.

The rule is to have same or higher voltage rating, match the polarity (positive + and negative - ) or shorts will occur, capacitance can be +20% or more - not too critical if it's for power supply filtering.

Tantalums have a better performance, but more prone to failure.

use newer parts, NOT from China
