Hi, J, 
How much for a complete kit? I have some Collins S-Line rigs to recover and 
would like to know,

BR,

Jim, HK3AHM/1


Hello to the List:  Here is  your chance to get some hard to find grid 
and parasitic suppressor resistors for your  Collins30L-1 transmitter 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. 
Same construction as Collins original suppressors using  (2 ) new Allen 
Bradley 100 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 o 47 ohms in instruction book 523-0122-00 4th edition.  This 
is the 
exact eplacement. $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 a 
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 eplacements but genuine 8-pin USA  sockets for the 5U4 and 5R4 
tubes 
and are ade  by  Amphenol or Cinch and which has  their name imprinted 
in the 
ceramic. as the mounting ears for replacement with bolts and nuts or can 
be 
mounted in a ole and secured with  the mounting ring. Note:   Will 
require  enlarging 
the hassis mounting  hole and drilling new holes for the mounting ears. 
CCA 
"The Signal" issue number twenty five details how this is  done. $12.50 
each plus 
$1.50 shipping. ombine 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 any of your  Collins or other receivers that have a  600 
output.  $18.00 plus $2.50 shipping in USA. Insurance  $1.30 additional 
if esired. 

Item #9.  Replacement fuse kit for  Collins 30S-1 or 30L-1. 
30L-1  F1 & F2 8A ABC  ceramic fuse.  $2.50 including shipping. 
30S-1 F201 AGC 3.2A - F202  12A ABC ceramic - F203 12A ABC ceramic- 
F204 8A ABC ceramic-  F205 1A ABC ceramic.  $4.00  plus 
$1.50 shipping.  Total of 7 fuses. 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 omes. Each fuse kit is in its own plastic bag.  Buy both fuse 
kits for 
$5.50 lus $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  (1.5nfd)  instead of 1000uuf 
(1nfd) but well within the tolerance ratings of the originals. Rated at 
500vdc, flash tested at 1000vdc. Mounts in the same holes as the 
originals. These are made by ERIE and are hermetically sealed and 
ruggedized and are primarily used for military and commercial usage. 
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.  Includes nut and washer which are separate from the 
sealed package.  $3.95 each.
