Description
This is a dial cord, stretch cord and dial lamp solution for Ten Tec 229 series, 238 and 4229 antenna tuners.The diameter of the non-stretch dial cord is VERY IMPORTANT because how it winds on the shaft of the roller inductor determines the calibration of the slide rule dial!
We provide the EXACT size of dial cord as originally specified by Ten Tec so your dial accuracy remains!
We also provide heavy duty stretch dial cord, also of the exact correct diameter.
Also included is THREE 12-14 volt LED bayonet base bulbs. (WHITE bulbs are included or you can have any combination of
BLUE
or
WHITE
, just let me know when you purchase. (note: we do NOT have RED)
We also have a lighting ON/OFF switch box for the panel lamps in another listing, see my eBay store
I made a simple way of providing ON-OFF for the panel lamps AND also provide the replacement LED bulbs AND stretch cord for the slide rule dial!
SEE MY EBAY STORE
What you get in THIS listing:
3 WHITE led bulbs (if you want RED or BLUE or ANY combination instead, send me a message when you are at the PayPal payment part of your purchase "send seller a message")
1 20" long stretch cord (tie knots to use 16" loop to loop), color of cord may vary
1 50" long non-stretch dial cord (46" needed), color of cord may vary
Ten Tec stringing picture is the last picture in this listing
(NOTE: extra bulbs available for each (if we can ship together), send a message and I will send a PP bill, get extra colors for a neat custom look or maybe you need bayonet base bulbs like this for other 5-14 VDC projects!
These great bulbs put out useful light down to 5VDC! I use them ALL OVER THE PLACE! I use them for 5, 6, 9 and 12 VDC applications!
ANTENNA TUNERS ARE NOT INCLUDED!
How to use:
3 WHITE led bulbs (you can add more bulbs at each or ask me for any combination of Red White or Blue)
1 20" long stretch cord (NOTE: tie cord for 16" loop to loop)
1 50" non-stretch dial cord (if your dial cord is still good, save this as a spare)
How to replace stretch dial cord:
These are your instructions! READ entirely BEFORE you start
Remove four screws from top cover (2 each side), remove top cover
Remove knobs (for my 229 and 238 tuners, the knobs are Torx T07 except the "SWR SET" knob which is a 1.3mm allen) Again, these are types and sizes needed for MY 229 and 238 tuners
Remove FOUR dark colored screws from corners of front panel
Remove three plug connectors from board near meter
Remove old stretched cord from dial pointer and the other end
Slide pointer to the right while turning roller inductor shaft clockwise, both to the end of travel
Tie knot in one end of new stretch cord, measure to make know in other end so loop-to-loop is about 16"
Tie knot and do the same with the other side but measure to have about 16" loop to loop.
Put one loop over end of dial pointer post
Run down and under lower right corner bushing
Run to the left and go to EITHER the lower left bushing OR the capacitor shaft
Carefully remove old bulbs, they are bayonet twist lock. BE CAREFUL when installing the new LED bulbs so you do not twist the front of the bulb and not be "pushed" into the socket to clear the two "barbs" on the sides of the bulb. Look carefully and see what I mean.
NOTE: on the 238, I bend the aluminum plate back in order to get to the meter bulb, that is much easier than removing the nuts and bolts for that plate. Do as you see fit.
See Ten Tec link (provided) for schematic for restringing non-stretch dial cord
Re-assemble in reverse order (be certain to have capacitor FULLY MESHED when dial is on 10)
Enjoy!
TIP: Always leave your tuner roller inductor pointer near the far right end of travel as this puts the least stress on the stretch cord.
TIP: Use green kitchen pot cleaning pad or fine sandpaper to "scratch" the bulb clear plastic lens for more light diffusion: IF you do this, BE CAREFUL not to twist and break the bulb plastic from the base! Replacement bulbs are each plus shipping, if shipped separate
NOTE: the lighting is not uniform across the slide rule dial. This is because of the Ten Tec design of bulb placement
The listing will come with all WHITE bulbs unless you specify all RED or BLUE or RED-WHITE-BLUE (send me a message when paying in PayPal. If you do not specify, you will get THREE WHITE LED bulbs
Personally, I like all three colors but the RED for meter and WHITE for panel is really a neat look. All WHITE is the brightest and best for the slide rule dial. All BLUE gives a really COOL look. All RED are great on the eyes for dark night viewing. And of course for us Patriots, use RED WHITE and BLUE!
