I am wanting the Ten-Tec idntification of the crystal filters in my Corsair.
On the PBT 80979 Rev A board the .25 position. I have a 6 pole filter with
two banks of three each crystals. On one crystal on one bank is stamped
48054. On the other bank of three, two crystals have the following: one
has NSI, another has 84-05. What is the 3 number Ten-Tec part for this
filter?
In the 0.5 position of the board another 6 pole filter with the following
stamped on the crystals 48053, NSI, 84-04. Similar to the .25 filter. What
is this Ten-Tec number:
In the 2.4 position an eight (8) pole crystal filter is marked 48074, NSI,
84-01. What is the Ten-Tec filter number for this filter?
On the board 80977 is an 8 pole filter with a crystal stamped 8321 and
another stamped in black ink 220. I believe the 220 is the Ten-Tec number
for this particular filter. If not please enlighten me.
I just sold a Corsair recently and the filters were plainly marked with 3
digit numbers. I am wondering what is the deal with these filters.
Thanks in advance for any information.
