TASCAM U9 PDI1394P23B FIREWIRE CHIP
Updated 28 March 2024
I have a good supply of the U9 firewire chip; PDI1394P23BD.
(Probably a "lifetime" supply, if I run out I will update this page accordingly)
These are NOS Phillips chips, the same exact chip that is on the board.

Below is Service Bulletin #0340, that is the chip in the photo; they are quite small.
It has been reported on the forum, that R52, 55, 60 & 63 also fail when the
firewire cable is inserted upside down.
There are 2 of the 56 ohm resistors right below the lettering, U9, on the
bulletin; they are very small.
Below is a photo of the U9 section on my FE-8. Its very similar to the 1884.

DISCLAIMER!
I have not yet done this repair myself, both my 1884's are in fine working order.
I can NOT confirm that R52, 55, 60 & 63 are the resistors that will need
replacing.
You'll have to check when doing the repair.
I CAN confirm that this is not a repair for the faint of heart!
It requires
advanced soldering skills!
Let me know if you need any further information.
