Electrolytic capacitors

[Glen Zook]

Virtually all of the modern electrolytic capacitors
are considerably smaller than the older versions.  You
can get capacitors from Mouser (www.mouser.com) as
well as other suppliers for very reasonable cost.

However, you will have to either use longer leads on
the capacitors to make up for the shorter length, or
else slightly modify the unit to move the connections
closer.

As for operation, the modern capacitors will be much
closer in value than the older ones.  You can buy the
20% tolerance capacitors which are much cheaper than
the 10% tolerance capacitors and be closer in value
than the originals ever though of being.  Most of the
original electrolytic capacitors had a tolerance of
-50% to +80%.  Thus, you really had no idea as to what
the actual value was.

I use 20% capacitors in all of the equipment that I
repair for others and haven't had a single problem.

Thus, if you have to, put double backed foam between
the circuit board and the capacitor to hold it in
place and then make the leads long enough to fit.

I found others Elect.Caps with similar MFD and Voltage
but they are shorter with the same diameter. Someone
can make me clear how to choose the less expensive
that will work and fit inside the SB220.
