Not sure where you found your info, but Central Semiconductor CEN-U07 / CEN-U57
have not been discontinued...they are still very much in production. If you buy
MPSU07 and MPSU57 from Bob Roberts, that is what you'll get. It's just that the
minimum order to get some is quite large and therefore cost-prohibitive.

Subject: VECTOR: WG 6100 upgrade updates & MPSU07 replacement.
I found a update / repair guide for the WG6100 on
http://www.pinrepair.com/video/wg6100.htm but it was last updated in 2000 and it
mentions some parts that are now no longer available.
In particular it recommends upgrading the MPSU07 with NTE49. Neither of which
is actually still in production.
The net mentions a CENU07/57 replacement but that is also discontinued.
Looking over my vectorlist archive I see suggestions of:
MPSU07 -> ZTX653 or TIP32C
MPSU57 -> ZTX753 or TIP41C
But nothing was definitive in those discussions (primarily about the speed of
the TIP’s and the 1W base limit of the ZTX part).
So is there a “new” version of the update guide out there which covers the
modern replacements? Or has anyone done long term testing of either the ZTX or
TIP solutions?
Thanks,
David
