I have a couple of subwoofer amps that have gone out.  A buddy has tracked down the bad components however we have not been able to locate replacments.  I have already run them through Occams' search engines stickied above (thanks Occam) to no avail.  The amps are surplus from Apex Jr, the Infinity OVTR 1 amps.  The parts I am looking for are:
SEC RIFS 250
TB2102
These are tranisitors.  I had a hit on the search engine for the TB2102 at American II, but there is no cutsheet available so I have not confirmed it is the correct component (different part number).  It won't do me any good if I can't find the SEC RIFS 250s I need.
Thanks,
Ed
