[Collins] Fw: {Collins} 30L-1 resistors & etc.

[David Knepper]

The CRA is endorsing the following information.  We have received samples
and the quality of the parts are exceptional.
It would make sense to stock up on these items

Thank you

> 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
> Hard to find feed thru ceramicon capacitors  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. The
> original Collins
> caps are rated a 1000uuf  and a tolerance rating of - 20% to + 100%
> whereas
> these are rated at + - 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 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.  $4.95 each plus $1.50 shipping..
