TVI filters for the transmitter For Sale:

Drake TV-1000-LP
Low pass filter for the transmitter
This is the filter that may also be used on the low
end of six meters, as well as HF.  It is good for 1000 W
below 30 MHz, and about 200 W up to 52 MHz.  
This particular filter looks like it just came out of the box.
The copper is all bright and shinny.  $ 35

Drake TV-3300-LP Low Pass Filter
This is a modern low pass filter to go between your
transmitter and antenna, and has been optimized to
have more attenuation in the 40 MHz region, where
many TVs have their IF. It is good for 1000 Watts
"average" according to the manual, and has over
80 db attenuation at 41 MHz.  SO-239 connectors
on each end. This one looks close to new, and also
has the single page "manual" with it.  $ 30

B & W  TVI filter, model  FL 10 / 1500 (also known as
model 425). Translated, this means that it cuts off just
above 10 meters, and will handle 1500 Watts. SO-239
connector on each end.  $ 30

Bud LF-601 "Variable Low Pass filter"
This filter is a bit over a foot long, and about 3 inches square 
with an SO-239 connector on each end.  In addition, it has 5 
variable capacitors on the top of it, that can tuned for maximum 
TVI improvement.  Although a bit harder to adjust, it should
give better TVI reduction.  $ 30

B & W  TVI filter, model  415
I have not been able to find specs on this model, but it says
right on it that it is for 52 ohm systems.  It looks like it will
easily handle 1500 Watts. SO-239 connector on each end.
Good shape.    $ 30

TVI filter, made by Communications Power, Inc in the USA.
This appears to be a bandpass filter for use on 10 (or 11)
meters, and is rated at 600 watts. It has provisions for tuning
the input and output for maximum TVI reduction. SO-239
connector on each end.  $ 30 

Prices do not include shipping from Florida.
