Re: [AMRadio] Johnson Viking II Mods

[Dave Aabye]

The best I've ever heard are the Level I and Level II mods described in ER some 
years ago.  Both can be done without drilling one new hole (completely 
reversible).  I've done them is Viking I's and II's.

I am reworking a Viking II. I see a few audio mods listed that vary in degrees 
of complexity. I'm wondering if one is favored over all others. 

Thanks,

I had the same problem several years ago.  Found a cheap picture frame with 
the correct thickness of glass and purchased a glass cutter at`Ace Hardware.  
Slick as a whistle.

[AMRadio] Vintage (OLD) Power Meters FS

[Dave Aabye]

This is a long shot for sure.  Do any of you collect (or sell) old meters from 
power distribution systems or the like?  By "old", I think the 30's, maybe even 
the 20's.  A set of nine such beasts was donated to my church's rummage sale, 
which is this weekend.  I'll send a photo on request from anyone with an 
interest.  These meters are heavy.  I think the set will weigh in at 25 to 30 
pounds.

Re: [AMRadio] age poll

[Dave Aabye]

I suppose I ought to add my statistics to those of the other confessors.

Turned 66 in July.

Originally licensed in August 1955 as KN9BCK (K9BCK in 1956).  Picked up W4QCU 
in 1966.

Though I am quite old enough at 66, I am too young to have experienced radio's 
golden era (which I regard as the 30s and 40s).

[AMRadio] Gates BC-1 Info

[Dave Aabye]

Good Morning AM-ers:

I just read Bill's (KB3DKS) post concerning 250 watt
operation of the BC-1T.  I'm probably entering in the
middle of a thread, but what the heck.

Two years ago I adopted a BC-1G.  Instead of using
series resistors, I opted to use a Variac.  Details of
that modification and other information of potential
interest to BC-1 users was recently posted at the
following link: 
 
http://pages.prodigy.net/w4qcu/Gatespage.htm

Who has made similar posts?  I'm interested in finding
out what others have done.

My BC-1G is on 75 meter AM just about every day.

Keep those 833s glowing!

Thanks to all who responded.  The tubes are spoken for
except for the two that are weak.  

The remaining tubes are useable and at $10 for the
pair + UPS, they might be attractive to someone.  If
nothing else, they'd make one heck of a table lamp!

Add actual shipping (boxed weight = 4 lbs, size =
9x13x14, from Zip 37830).

Hi Ronnie,

Yep.  I need to clear out some excess stuff.  I've now

Group 1.  Tested strong in my BC-1G

1. Amperex $35
2. Amperex (marking came off while cleaning) $35
3. General Electric $35

Group 2.   Tested good to strong

4. National Electronics (China)  $20
5. National Electronics (China)  $20

Group 3.  Untested - look good

6. Electronic Enterprises (China)  $15
7. No marking (probably China) $15

I though I'd seen most everything, but...

$4,000 opening bid on a vintage 833-A.  I suppose
"vintage" is all-important, but it's not even a

original price was around $10,000!  You KNOW where

[AMRadio] An Apology

[Dave Aabye]

Fellow AM-ers,

My recent message (Vote on RM-11305), although
motivated by the best of intentions, resulted from a
serious misunderstanding.  In short, I was blissfully
unaware that two significant rule making proceedings
are underway.  (Yep, I live in a vacuum...tube.) 

My concern is the preservation of AM as a viable mode
of operation.  To that end, I should have suggested
opposition to RM-11306.

I'm sorry for and embarrassed by this mix-up.

73 de Dave, W4QCU
Oak Ridge, TN

[AMRadio] Vote on RM-11305

[Dave Aabye]

The recent message fom Don, K4KYV (Subj:  Web page
appears in opposition to RM-11305) contains the
following link, which makes it VERY EASY to express
one's opinion on RM-11305 directly to the FCC.  

http://gullfoss2.fcc.gov/prod/ecfs/upload_v2.cgi

Even if all you wish to say is "I oppose RM-11305",
please do so.

73 to all,

Happy Thanksgiving Paul!

Thanks for the audio file, which I will open as soon
as this message is sent.  With my dial-up service, it
will take several minutes.

I can try 40M but have some difficulty getting my SWR
down.  I need to patch in a few extra feet of ladder
line to get within the range the matching network can
handle.

Missed you on 75M so far this week.  Conditions have

Hello Tony,

Nice to hear from you.

The 5100B is spoken for at $600.  But, if you want it,
I will ask for verification.  It would be nice not to
ship.

The 4350A/spkr is $350.

Are you coming to Ten-Tec?

The time has come to part with much of my boatanchor
collection.  So, with some reluctance, the first group
of equipment is "on the block":

Transmitters:
B&W 5100B
Heath Apache/TX-1
Glbe Scout 65A
Stancor 20P
Meissner Signal Shifter 1943 Model

Receivers:
TMC GPR-90 with GSB-1 SSB adaptor
National NC-173/spkr
National HRO-5TA1/PS/spkr/4coils&box
National NC-240D/spkr
Hallicrafters SX-16/spkr
Hallicrafters SX-28
Hallicrafters S-38C
RME-45B/spkr/DB20 preselect.
RME-4350A/spkr

Photos are available on my webpage.  Prices and
additional information will be provided on request. 
For the most part, these pieces are in very nice
condition.  Prices reflect condition, as well as my
investment in each piece, and will not be attractive
to re-sellers.  

I can deliver to upcoming hamfests at Ten-Tec,
Chattanooga, and Oak Ridge. Folks heading this way can
also checkout and pickup at my home.  Some items can
not be shipped.

Thanks for looking.

Hi Jim,

My "project" is a converted Gates BC-1G.  It's on the

Guys and Gals,

Does anyone have a pair of NOS 833As (NOT PULLS and

Hi Ronnie,

I'll try a SWAG.  I'don't think that the 6L6 is a drop-in replacement for the

Maybe the 6L6 is not properly biased?  Have you tried a pair of 6V6's?

I imagine the tubes are running PP Class A and wonder if the plate to plate

Ronnie,

The circuit is on p. 196 in my 1968 Handbook.

It looks to me that S1 needs to be NON-shorting.  For S2, I can find only two
wafers on the schematic (S2A and S2B), so it looks like 2-pole is OK.

[AMRadio] Re: 500 Transformer

[Dave Aabye]

Hi Gary,

Yep, it's a bummer!

WZ1M wants $260 to rewind the existing transformer.  Peter Dahl sells a 
replacement
for $285.  I think that Dahl offers a better deal because it is a hypersil unit
with a 500 ma CCS rating.  I believe the original is rated 400 ma ICAS.  Only
drawback is the need for 4 new mounting holes.

I replaced the tube recitifiers with solid state units shortly after purchasing 
the
500 (about two years ago).  I also inserted thyristers in the primary leads to 
cut
down on inrush current.  I wonder if you have any further protective measures to
suggest.

Re: [AMRadio] Requium for Tranny?

[Dave Aabye]

Hello Gary,

Thanks for the suggestion, which I believe has proven to be conclusive.

I hooked my Variac to the primary and slowly increased the secondary voltage.
The caps were disconnect from the rectifiers, so the transformer was "all by
itself".  At about 700 volts, the voltage started to jump just a bit.  At
maybe 750 v, the secondary emitted a puff of smoke with an accompanying hiss.

I think it is clear that the transformer is shot.  Time to call Peter Dahl!

Again, thanks for your input.

[AMRadio] Requium for Tranny?

[Dave Aabye]

Good morning all,

I need some advice.

Earlier today my Viking 500 tripped off with the familiar odor that we
have all come to dread.  I only lost HV.

After I got the cover off the PS-Mod unit, I was surprised to see
nothing unusual.  Then I started sniffing, and that led me to the HV end
of the plate transformer.  I removed the end cover and again saw nothing
unusualonly the odor, which by then was beginning to dissipate.

Resistance measurements lead me to think that some windings may be
shorted.  One side to center tap reads 110 ohms.  The other reads 95.
The manual says 100 on either side.  The HV secondary shows infinite
resistance to ground, but that is with no juice applied.

What I'm wondering is whether the 15 ohm difference is conclusive.  If
not, what other tests might I make without risking further damage?

Thanks in advance for any advice,

Dave, W4QCU

Re: [AMRadio] Which older rig would be easiest to renovate/repair/and get running again properly

[Dave Aabye]

Choosing from among the 5100B, 32V3, Apache, Viking I, and Viking II, my vote 
goes
to either the Viking I or II for ease of maintenance in the 100 watt class.
Operation is pretty good too.  The RF section is fine.  Audio can benefit 
greatly
from the mods described in the June and July 1998 issues of Electric Radio.  
With
those mods, nothing on the air sounds significantly better (my opinion, of 
course).

73 and Happy Thanksgiving,
