Hi Jay,

I don't have an answer to your question about the capacitor values in 
the 282 filter, however I do have some information about the numbers on 
some Ten-Tec filters that you and others may find helpful. My guess is 
that the filter that has "8025" on it is a stock code 48025 filter. 
Unfortunately I do not know what model that is.

Ten-Tec filters have both a model number and a stock code. Sometimes 
both of these numbers appear on  the filter, each number ink stamped on 
one of the crystal cans, and sometimes only one of the numbers is there. 
Sometimes only part of one of the numbers is legible. If both numbers 
are there, they are usually in two different colors of ink.

Model Number / Stock Code
216 / 48161
217 / 48306
218 / 48037
219 / 48055
220 / 48058
221 / 48243
282 / 48054
285 / 48053
288 / 48075
unk / 48127 6 kHz BW 9 MHz IF filter used for AM in Paragon
unk / 48074 ? possibly and alternate stock number for the model 220 ?

There are some gaps in this information. I would like to collect more of 
this information. It can be very helpful when we have an unknown filter.

Some of this data came from a single page included in the manual for my 
first Ten-Tec radio, an Omni VI. The heading of that page is TEN-TEC 
INSTRUCTION SHEET MODELS 216, 217, 218, 219, 220, and 221 CRYSTAL 
FILTERS. Some of this information came from the PASSBAND TUNING BOARD 
SCHEMATIC in my Paragon II manual. The rest of the information came from 
looking at the filters in my rigs.

Next time you have your rig open, please take note of the numbers on 
your filters and post any accurate information on the reflector, so we 
can  develop a complete cross reference list.

Thanks,

DE N6KB
