Some Hard-to-Find Kenwood Parts

 

I was shocked to see so many parts needed for successful restoration of these wonderful rigs going away.  I guess in this day of surface-mount digital equipment, there is just not enough demand to keep manufacturer's production lines going.  Since I repair and restore these Kenwood classics, I have to find or make what's needed to keep these rigs up and running.

Here's some parts that I have available for your restoration efforts, I will try to continually add to this list.  I have accumulated several donor rigs, so I have Kenwood coils, caps, meters, power transformers, etc. on a limited basis.  Please feel free to contact me with your needs for specific items.

 

SHAFT COUPLER

These are getting hard to find, and very expensive for the 4-setscrew units.  I finally tooled up, and made exactly what we need for the Kenwood bandswitch and other shaft repairs. 

Solid brass, with four stainless steel 6-32 setscrews.  The outer diameter is only 0.375", so you can install it without taking the radio apart!  See INSTRUCTIONS.

These are made for metric use, with Kenwood, Yaesu, and other Japanese brands, with 0.236" shafts.  The nominal 0.244" I.D. is a nice slide fit with the metric shafts, but will not fit 1/4" U.S. shafts. 

SC-M1  7.50 Each

 

3-PACK SHAFT COUPLERS

Enough to do all the broken couplers on most rigs.  Same high quality, solid brass with S.S. setscrews.   Metric sized, a nice slip-fit with the 0.236" shafts found on this vintage gear.  Will not fit 1/4" shafts.

SC-M3  19.95 per 3 PK

Installation Instructions

 

REPAIRMAN'S 10-PACK

For the serviceman or repairman who would like to use a 4-setscrew coupler of just the right size, to repair bandswitch coupler problems with the least amount of effort.  Solid brass with stainless steel setscrews, these should make for a lifetime repair.

These are Metric, and will not fit 1/4" shafts. 

SC-M10  59.95 per 10 PK


4-PK KENWOOD PANEL LAMPS

The right shape, size and wattage for replacement of all Kenwood Panel Lamps including TS-520, TS-530, TS-820, and TS-830 models.

Rated 12V, 50 ma, 4mm dia., 6" wire leads.  Long life, and brightness & color matches originals perfectly.

PL-4   5.00 per 4 PK

PL-20 19.95 per 20 PK

 

REPLACEMENT SPEAKER

Replace the buzzing and/or damaged speaker in your 520, 820 and 830. 

These are good quality 8 Ohm 2 Watt 77mm speakers.   Larger magnet structure, higher power, higher excursion, and better bass response than the original.

Uses spacer washers under the brackets to accomodate the slightly thicker frame.  Required washers are included with each speaker.

Bottom picture shows this speaker mounted in a TS-830S with the original hardware, TS-520 and TS-820 would mount similarly.

The TS-530S doesn't use a plug like the other models, you will have to improvise a pluggable connection.

SP-77     3.95 Each

Individually boxed



REMOTE VFO CABLE KIT
for TS-530S and TS-830S

NEW!

I was going to offer completed cable assemblies, until I realized that it took me an hour to assemble one! 

These kits contain the two hard-to-find Kenwood-style 8-pin DIN plugs (The ones with the strange spacing) and a 25" length of nice multiconductor shielded cable.  The cable is round, very pliable, and works perfectly.

The top picture is the kit components, and the bottom picture shows a completed assembly.  All you add is solder and an hour of your time.

Assembly instructions are available here.

Gold plated contacts, 18"+ length matches originals and works perfectly.

CA-5     19.95/Set

 

RESISTOR KITS FOR FINAL REPAIR

Resistors are not hard to find, but it's often a pain to find exactly what you need in small quantities, and shipping and handling fees may get excessive.

I have 2 Kits, one for the 520/820 series, and the other for the 530/830 series.  Included are the cathode resistors and a set of 3 screen resistors. These will replace the resistors that are usually damaged or destroyed in rigs that have been overdriven. All resistors are non-inductive metal film or metal oxide, flameproof construction, the good stuff.

RK-52 for 520/820  1.99 Each
Consists of (2) 10 Ohm 1W 5%, (2) 100 Ohm 1/2W 1%, (1) 470 Ohm 1W 5% 

RK-53 for 530/830  1.99 Each
Consists of (4) 20 Ohm 1/2W 5%, (2) 100 Ohm 1/2W 5%, (1) 470 Ohm 1W 5%

KENWOOD HIGH-VOLTAGE REPAIR KIT

If your HV seems to sag a bit under key-down, odds are that your 25+ year old HV electrolytics have decreased in capacitance, or increased in ESR.  Either way, it's time for replacement.  This kit provides 2 modern high quality 150uf 500WVDC electrolytics, two 0.01mfd 1KV bypasses, and two 470K 1W 500WVDC resistors to restore the entire HV filter section.

The new electrolytics fit the existing mounting hardware perfectly, and the 50% increase in capacitance will provide higher power output.

HV-150B  Kit   24.95

 
 

KENWOOD FINAL CAGE PARTIAL REPAIR KIT

Kit consists of the 3 most commonly damaged, hard to find parts when the final section has been overdriven.  Includes:

PANEL FASTENERS  

Snap in Plunger and Grommet sets fit the original mounting holes perfectly!  Used on the TS-520 and TS-520S, these fasteners attach the side cover plate that conceals the VOX and bias adjustment pots.

Plunger heads are 0.1" taller and shaped to allow for easier removal - No prying tool needed.  Bottom photo shows the original (back) and the new (front) fasteners installed.

HW-25   Pkg/3    1.50

 

6A 250VAC FUSE

I get so many rigs in with 32V automotive fuses that I suspect the proper fuses are less common on your grocer's shelves! 

The 32V fuses may not open (fuse) properly, you really should use the right part.  3AG fuses rated 6 Amps, 250VAC fast blow.

FS-106   Each   0.65

FS-106-10 Repairman's 10-Pack 5.50

 

12BY7A DRIVER TUBES

I have a limited supply of NOS 12BY7A driver tubes, from several manufacturers.  I test them all, they must test new or I will not sell them.  While my supply lasts, you can get them at a very reasonable price.  Provided in the original manufacturer's packaging.

12BY7A NOS    11.95 


KENWOOD ALIGNMENT TOOLS


It is far better for your rig if you can keep metallic tools as far from the alignment adjustments as possible!   Please, don't ever use allen wrenches to try to adjust your 520 & 520S coils - The core will simply break and become immovable.  Also, never, ever use a metallic adjustment tool for neutralization!  You will make big sparks, and you could become an SK!

AL-1 is a double-ended nylon hex alignment tool that fits the coils in the 520 and 520S perfectly.  Two ends, twice the life.  5.5"L

AL-1    2.75

AL-2 is a double ended 1/4" hard plastic screwdriver with thin blades that will fit the neutralization cap on the 520, 820, 530, and 830 series.  It is tough enough to take the torque in that thin slot - Mine is 2 years old, tested on over 200 rigs.  6.75"L.  It also slides under the Kenwood knobs and pops them free without marring the panel.

AL-2    2.75


 

DUMMY LOAD RESISTOR KIT

Kit of twenty (20) 1K 3W 5% Metal Film resistors to build a dummy load as shown on my web page here:

http://k4eaa.com/dummy.html

Selected especially for their accurate impedance at 1K resistance out to over 200 MHz.  Good power handling, could be used air-cooled for short durations, such as 100W for 10 seconds key down, or several minutes in a mineral oil filled quart can as shown at the above link.

NEW!  Now the kit also includes a BAV21 diode!

LK-R1    12.50

EXTRA LARGE
SCHEMATIC LASER PRINTS 

High quality schematics printed on large format 24" x 36" sheets.  These can actually be easily read by most of us!

These are black and white prints made on a very large laser printer and are extremely crisp and legible.   I have these PDFs available for free download here:

http://www.k4eaa.com/schematics.htm

The problem is getting them printed in a large size at a reasonable cost.  These are printed from the original HUGE files from my scanner, before compressing for download.

The price includes USPS shipping, and a storage/mailer tube with plastic end caps for safe storage between uses.  Prints are rolled, not folded, into 24" x 2" sturdy cardboard tubes.

If you're like me, you might even consider framing one for your shack!  I will be adding more schematics as time and finances permit, right now the TS-830S main schematic is available.  See the PDF link, above, for content.

SM-830S  12.99
TS-830S Main Schematic

Includes shipping within the U.S. and a reusable storage tube.

Save!  Up to five prints will ship in the same tube for 7.50 each additional print.  Great for clubs, groups, and friends.

 

 

SHIPPING AND ORDERING INFORMATION

Most small items, or combinations of small items will ship in a padded mailer or small box via USPS 1st Class Mail for 1.99 or 2.99 depending on size.  If you prefer Priority Mail, up to one pound ships for 4.99.  I also ship to Europe, Australia and Canada.

Please drop me an email for full contact info and payment details.  I will send you an invoice you can then either print and mail with a check, or copy and paste into your PayPal payment.

When you mail or email your order to me, please include (1) your order, (2) your shipping address, and (3) your email address.   Please don't make me search through thousands of emails trying to guess if either "Joe" or "Joe Snuffy" is really jrs102@bilge.net . . .  8^)

Thanks, and Best 73's, Ken K4EAA
