So nice to see that others are enjoying Skycraft!

I still have meters in service that I bought from them in the 1960's.

Just this week I found a small, quiet box fan for cooling the R-390's hot spot.

We always try to drag out-of-town engineering oriented folks there just to see their
expression when entering the door.
The best one was a CISCO Multicast engineer. 

After entering the doorway, Reed says 'I am in need  of a 30 ton bottle jack for 
my press project"
Reed - you are tripping over one, look down......

I've had several go bad in an SX-101 MKIII.
It's why my new DVM has capacitance testing, and I still have an old 
eath C-3.
You never know WHAT might go bad.  I'm developing a "habit" of lifting 
ne leg of damn near every component, so I can test them.
I bought a whole batch of metal film resistors too!

The apparent failure mode of the dogbone caps is whether they were 
oated on the INSIDE.
Every single one I've found bad, had NOT been!

Now if you want some Real capacitors, look at the offerings in
ww.tubesandmore.com (Antique Electronic Supply) for the audiophools.
aps at $37. each!  Handmade with paper and beeswax.  Maybe the price
s so high because the beekeepers have to risk their lives getting
he wax away from killer bees.  Or does wax from honeybees make for a
weeter sound?  You could make a name for yourself among the audiophools
y doing some "research" to show that there are differences in audio
uality according to the kind of plants the bees are gathering their
ectar and pollen from.

kyCraft Surplus is a must-visit destination if you're going to be in Orlando.  
ver 3 separate visits, totaling about 4 hours, early this month I had a great 
ime ... and still didn't see everything they had in inventory.

ost of their prices are terrific.  I purchased a lot of screws, nuts, solder 
ugs, solder posts in quantities of a hundred to get the 30% discount.  I found 
ome aluminum L-brackets for 15 cents each that are going to be perfect for 
read-board construction projects.  Transformers of all flavors are on the 
helves and the isolation xfmrs and 6.3 vac, 3 amp xfmrs were priced right and 
o I purchased several of each.

witch hardware, which is either expensive or not available locally in 
reensboro, is available at SkyCraft at attractive prices and so I purchased the 
ssociated washers, nuts, and internal lock washers -- all at very attractive 
rices.

 found some thin 6" by 3/8" brass strips that I'll use in some projects in the 
orks.

ot surprisingly, the box of R-390 mini connectors that I'd seen in previous 
isits was empty of those flavors this year, but had beaucoup of other types in 
he box.

heir website has photo's of the inside of their store -- go to the about us 
ab, and down toward the bottom of that page there is a store photo's tab.  See:

I don't think this is for the audio guys, but I could be wrong. The tube 
rices are jacked up for them since they are willing to pay it, but 
here is a different market for paper caps and old resistors.
I have a few old issues of ARC magazine and there are some interesting 
rticles about restoring am, and am/fm radios below and at museum level. 
his is where a restorer would want the old paper caps just for looks as 
he radios are brought up to perfection inside and out. I know what some 
re restored with new caps and old caps are carefully placed over them 
o hide the work.

arry

 Now if you want some Real capacitors, look at the offerings in
 www.tubesandmore.com (Antique Electronic Supply) for the audiophools.
 Caps at $37. each!  Handmade with paper and beeswax.  Maybe the price
 is so high because the beekeepers have to risk their lives getting
 the wax away from killer bees.  Or does wax from honeybees make for a
 sweeter sound?  You could make a name for yourself among the audiophools
 by doing some "research" to show that there are differences in audio
 quality according to the kind of plants the bees are gathering their
 nectar and pollen from.

I'm happy to hear it is still there. It has been around for what, 40 years 
r so? As a Tampa native until 1987 I drove from Tampa to Daytona countless 
imes and often stopped at Skycraft. Even as a "young married thing" in the 
id-70's my wife completely supported my wandering up and down the aisles. 
o this day she describes my interest in copper, whether wire, terminals, 
ittings, antennas, or in general, as "liking bright shiny things to bring 
ack to the nest". After looking at the innards of my R-390A some years ago 
he started referring to all of my boatanchor radios as "radio machines". 
a!  A better description was never coined!
Though I now live a long way off I still visit FL very occasionally and hope 
o return to Skycraft one day. It is a marvelous stop for any solid copper 
oatanchor.

 SkyCraft Surplus is a must-visit destination if you're going to be in 
 Orlando.  Over 3 separate visits, totaling about 4 hours, early this month 
 I had a great time ... and still didn't see everything they had in 
 inventory.

 Most of their prices are terrific.  I purchased a lot of screws, nuts, 
 solder lugs, solder posts in quantities of a hundred to get the 30% 
 discount.  I found some aluminum L-brackets for 15 cents each that are 
 going to be perfect for bread-board construction projects.  Transformers 
 of all flavors are on the shelves and the isolation xfmrs and 6.3 vac, 3 
 amp xfmrs were priced right and so I purchased several of each.

 Switch hardware, which is either expensive or not available locally in 
 Greensboro, is available at SkyCraft at attractive prices and so I 
 purchased the associated washers, nuts, and internal lock washers -- all 
 at very attractive prices.

 I found some thin 6" by 3/8" brass strips that I'll use in some projects 
 in the works.

 Not surprisingly, the box of R-390 mini connectors that I'd seen in 
 previous visits was empty of those flavors this year, but had beaucoup of 
 other types in the box.

 Their website has photo's of the inside of their store -- go to the about

 had the same question about how does SkyCraft survive.  But here's what I 
bserved.

arge numbers of buyers are in this store all the time during the week and they 
ob it on Saturdays.  Everytime I was in the store, there were at least 10 to 15 
eople exploring the store looking for parts.  During the week days that I was 
here, I noticed home owners and electrical contractors buying all manner of 
lectrical items ... some priced at $25 to $100 each.  Which apparently was a 
ot cheaper than they could buy a Lowe's or Home Depot.  How do I know they were 
lectrical contractors?  When I arrived and left, their panel trucks were in the 
arking lot!

n Saturday I arrived about 2pm and the place was like an ant hill.  There must 
ave been 50 people scrounging around looking for parts.  About a third of those 
ere clearly students looking for semiconductor and robotic type parts.  Another 
hird were probably hams.  And another third we DIY home fixer uppers...  Now 
ear in mind that was 2 PM.  I'm guessing the crowds starting showing up when 
hey opened up at 9 AM...  And on and on it goes all day long on Saturday.

egarding SkyCraft's nut.  I imagine their rent is not too high.  They are not 
ocated in the high rent district.  Cutting the other way, though, is on 
aturday, there must have been at least 5 or 6 (or more) sales people roaming 
he floor helping people find what they were looking for.  And the sales people 
ere busy, busy, busy.  None of them were standing around chewing the fat....  
t was very nice to have someone to turn to ask about things, but then I 
ondered how in the heck can they afford to pay these people?  Dunno.  One thing 
s for sure they didn't make much off of me or probably other hams.  So they 
ust be making it off of the home owners and electrical contractors....  It's a 
uzzle for sure.

ne other thing I noticed.  Behind the counter, just to the left, there was a 
uy on the computer the entire time I was there.  I'm guessing he was probably 
uying surplus from some source .... and maybe selling stuff to other buyers....  
 
nyway, judging from the volume of people coming in ... and buying, SkyCraft is 
ot going out of business anytime soon.

Tom

What I don't get is, how can these places stay in business selling small parts 
ike that?
hey have to crack a nut of several thousands of dollars a month in rent and 
ages,
ven if both are below local market average. Maybe I shouldn't ask, because 
sking
reaks the spell. But I have seen so many surplus stores disappear after a few
easons trying to make a formula I see as unworkable, work. Again, how can you
ake a surplus store formula work by selling small parts??? -Hue Miller
