The MC1558, LM1558 and uA1558 are subs for the CA3458. The T suffix
probably indicates that it's in a metal TO5 can. If so, you might have to
get a type 1458 chip in a metal case. Unicorn Electronics
(http://www.unicornelectronics.com/IC/LINEAR.html) has the LM1458H in a
metal can. Same chip, just commercial temperature range rather than the
Industrial temp range.
