[Collins] Parts for 30L-1- KWS-1

[J. A. Call]

Hello to the list.   Here is  your chance to get some hard to find parts
for the
Collins 30L-1 & KWS-1 gear and other items as well.

Item #1. Replace those old tired, burnt out,  out of tolerance grid
resistors with four (4) brand new 47-ohm 1 watt Allen Bradley carbon
composition grid resistors.  Shown on the 30L-1 schematic as R21, R22,
R23, R24.   You should have these as spares in case you develop a grid to
plate short in one or more of your 811A's. These are the ones that
vaporize.  Price is $5.00 for four (4) plus $1.50 FIRST CLASS - USA 
shipping plus $1.30 insurance if desired.

Item #2.  Replace those old tired, burnt out, out of tolerance parasitic 
suppressors in your Collins 30L-1 with two (2) new homemade parasitic
suppressors. Same construction as Collins original suppressors using 
(2) new Allen Bradley 100 or 120 ohm 2  watt carbon composition 
resistors   
These are shown as Z1 and Z2 on the 30L-1 schematic. $6.00 for  the pair
plus $1.50
FIRST CLASS USA  shipping. plus $1.30 if insurance is desired.

Item #3. 1 each  47 ohm 2 watt carbon composition resistor shown as R9 on
the Collins 30L-1 schematic.  Collins changed the value of this resistor
from 82 ohms to 47 ohms in instruction book 523-0122-00 4th edition. 
This is the exact replacement. $2.50 ppd.  

Item #4.  1 each 10K ohm 2 watt carbon composition resistor shown as R15
on  the Collins 30L-1 schematic. This resistor changes values due to
heat.  Exact replacement. $2.50 ppd.

Item #5. 2  each 10 ohm 2 watt carbon composition resistor shown as R17
and R18 on the Collins 30L-1 schematic. Resistors open up or change value
due to short on B+ line. $5.00 ppd.

Item #6 1 each  Dale 1 ohm 1% 5 watt wirewound resistor shown as R8 on
the Collins 30L-1 schematic and located on bottom of  B+ resistor string.
Acts as  meter shunt.  $3.50 ppd.

Item #7.  Replace your old style tube sockets in the Collins 516F-2 AC
power supply with  genuine ceramic sockets.  These are not the inferior
Chinese replacements but genuine 8-pin USA  sockets for the 5U4 and 5R4
tubes  and are made  by  Amphenol or Cinch and which have  their name
imprinted  in the ceramic. Has the mounting ears for replacement with
bolts and nuts
or can be mounted in a hole and secured with  the mounting ring. Note:  
Will
require  enlarging the chassis mounting  hole and drilling new holes for
the screws for the mounting ears.  CCA "The Signal" issue number twenty
five 
details how this is  done. $12.50 each plus $1.50 shipping. combine items
and 
reduced shipping charges. Only a few left. 

Item #8.  New Military grade UTC audio output transformer.  Part 
#UTC-F-7101.   Specs - 600 ohm  primary and 8 ohm secondary.  2 watt. 
Frequency response 250-5000hz.  Round potted metal case  1-1/2 inches
high and 1 1/4 inches diameter (same diameter as a flashlight "D" cell). 
Has a diagram and connection pinout on the case.  Useful to add a 
speaker to your Collins 51S-1 or other receivers that have a  600 ohm
output.  $18.00 plus $2.50 shipping in USA. Insurance  $1.30 additional
if desired.

Item #9.  Replacement fuse kit for  Collins 30S-1 or 30L-1.

30L-1  F1 & F2 8A ABC or AGC  fuses.  $2.50 including shipping.
30S-1 F201 AGC 3.2A - F202  12A ABC or AGC - F203 12A ABC or AGC- 
F204 8A ABC or AGC-  F205 1A ABC or AGC.  $4.00  plus
$1.50 shipping.  Order a kit now and tape it to the back of your 30L-1 or
30S-1  so you will have the exact replacement when the time comes. Each
fuse kit is in its own plastic bag.  Buy both fuse kits, total of 7
fuses,  for
$5.00 plus $1.50 shipping.

Item #10
Feed thru ceramicon capacitor for the Collins 30L-1.  Shown as C35 thru
C59 on the schematic.  These are 1500uuf  instead of 1000uuf  but well
within the tolerance ratings of the originals. The originals were rated
at 1000uuf (plus 100% to minus 20%) . Rated at 500vdc, flash tested at
1000vdc. Mounts in the same holes as the originals. These are made by
ERIE and are hermetically sealed.   They are NOS in original sealed
weatherproof packages.  These are style 327 that have a hook on each end
which  are designed for tie points for several connections which can be
bent to suit your particular needs.  Note:  Does not include the nut and
washer.  Use the ones from the old feed thru.  $4.95 each.  
Free shipping for five or less.  $1.50 otherwise.  

Item #11.  11-pin AC power cord for the Collins 75S-line and 9-pin for
the Collins 51S-1  receivers.  Connectors have black metal shell with
cable clamp.  
Used but in good condition with new 6 foot cord.  $14.95 plus $2.50
shipping.

Item #12.  Hard to find  4-megohm 1% 2-watt 2KV resistor R11 for the
Collins 30L-1. 
Replace it with a  4-megohm 3-watt  1% 30KV resistor  rated at 200
degrees C (452 degrees F)
axial leads. When your R11 resistor fails you will no longer be able use
the 30L-1,  so a spare or two would come in handy.  Over  a long period
of time the original R11 changes value which in turn changes the reading
in the plate metering circuit. The original R11 was rated at 2KV at
2-watts.  The ones I am offering are rated at 30KV at 3-watts.  This
resistor has a voltage rating which has a  1400% 
higher margin and the wattage rating is 50% higher than the original.
Length 2-inches long, 1/4 inch in diameter with 1 1/2 inch leads on each
end. $17.50 each plus $1.50 shipping .

Item #13. NEW  Bussman HVB-1 high voltage fuses for the Collins KWS-1. 
1A 2500v. 4.5inches
long,  .41 inches in diameter.  Due to nature of the fuse NO  replacement
if you blow it out. 
$14.50 PLUS $1.50 shipping.

Item #14.  Five (5) dial lamps for the Collins R390 Re90A etc receivers. 
6V 200ma.  Midget
flanged base.  Average life 1000 hours.  $4.20 plus $1.50 shipping.

Item #15.  Homebrew compact solid state 3-minute time delay for the
Collins 30S-1
transmitter.  It is a direct replacement for the Amperite (115NO180) 180
second time
delay ballast tube shown on the 30S-1 schematic as K202.  No changes
required,
no holes to drill.  Just plug it in and ready to go.  If you want a
visual indication of when
the 30S-1 is ready to transmit it is a simple matter to cut one wire and
solder two
connections to accomplish this feature.  If you decide to sell the 30S-1
later just 
reconnect the cut wire.  Information sheet and schematic included.  If
you want pictures
of this item send me an e-mail  and I will send you an e-mail with
picture attachments. 
Good to have a spare when  your ballast tube gives out.  $32.50 plus
$3.50
shipping and insurance.

Item #16.  Microphone male connector for the Collins KWS-1, Heath, B&W
and others. 
Amphenol part number series 80-MC2M.  Specs. 2-contact with cable spring

and a screw type ring on the mating end to make a secure positive
connection.
