Hi everbody,

This is Phil, formerly . The email address above is my
(primitive) attempt to reduce spam. To email me, remove my head.

I'm going to do the same thing I did last year, ship a bunch of tubes to
various tube dealers, and I want to again make them available here
first. Actually, I had so many buyers last time that I never got around
to sending the rest of the tubes to the dealers! Unfortunately, that
means that many of these are "left over" from last year, but there are
quite a few new tubes as well. This year, I am determined to sell most
of the left overs to the dealers, regardless of how many I sell here, so
I can free up some room in the extra bedroom! Almost impossible to have
a guest at present ...

As before, I am listing three prices per tube type, the highest dealer
bid price I could find, the AES (Antique Electronic Supply) selling
price (or TubeWorld if AES doesn't have a selling price), and a "buy it
now" price, which is usually, but not always, 1/2 of the AES price.
Tubes with a "#" sign in front of the bid price are not on current bid
lists, and have an old bid price. Tubes with no bid price do not and
never did have a bid price. All tubes are NOS in their original boxes,
unless stated otherwise (an asterix next to the tube number indicates a
used tube). I have tested some of these, but in most cases I will test
them after you express an interest in them, and then let you know the
test results along with the shipping costs, after which you can decide
if you want to go ahead and buy them. If they are sealed in a plastic
bag, or you want a huge number of really cheap tubes, I'll ask if you
(hopefully) want me to test just a sample of them. Tubes that have
already been tested have the results shown as, for example, "min =
1000/2000, GE#2 = 2000/4000 (95%)," which means this tube has two
sections, the minimum for a good tube on my tester (Hickok 539C) is 1000
for the first section, 2000 for the second section, the second GE tube
in the list tests at 2000 and 4000 for the two sections, and the weakest
section drops to 95% in the "Life Test." The Life Test drops the heater
voltage 10%, which causes most new tubes to drop to 95% to 98% of their
"Normal Test" reading. In the old days, any tube that tested 80% or
better on the Life Test was considered to have quite a bit of life left
in it, and left in the radio or TV.

I did not have time to research the prices for most of these tubes,
which is why most of my "buy it now" prices are simply 1/2 of the AES
price. If you offer to buy tubes at the "buy it now" price, then I will
immediately mark those tubes as yours if they are still available, email
you (I will also email you if they are not available), and ship them as
soon as I get your payment. If you think that my "buy it now" price is
too high, feel free to offer a price between the dealer bid price and my
"buy it now price." I will wait until Thursday morning, Oct. 13 (dang,
almost Friday the 13th), to see if anyone wants to make a higher offer
or exercise the "buy it now" option, but if you are correct about what
the price should be, then probably no one else will bid a higher amount,
and those tubes will be yours at your price. And don't worry, I will not
"play games" by telling you that someone has offered more money, in an
attempt to get you to raise your bid! If the tubes are still there
Thursday morning, you get them for your bid price. I may keep a few of
the "leftover" tubes, but most of them will immediately be shipped to
the dealers, hopefully by Friday morning.

You pay shipping costs only, no handling or packing fees, although this
means that I will want to make at least $5 per order over what I could
make by simply selling the tubes to the dealers. I will ship them using
your choice of USPS First Class, USPS Priority, USPS Parcel Post, UPS,
FedEx Ground or FedEx Air in the States. The least expensive method is
usually First Class (up to 13 ounces), then Parcel Post or Priority (1
or 2 pounds) then FedEx Ground (over 2 pounds). Internationally, USPS
Air Letter Post (up to 4 pounds, no insurance), and Air Parcel Post (up
to 44 pounds, insurance optional) are usually the least expensive
choices (by air). I have a good weight scale, so I can calculate the
shipping costs to the penny almost every time (unless it's within 1/5
ounce or 8 grams of a price change). For payment, I can take PayPal,
BidPay, a wire transfer to my bank account, a money order, or a check,
but checks need up to two weeks to clear.

I formatted the tube list in fixed width font, so if it looks screwed
up, try putting it into a reply/composition and block change the font to
fixed width. Email me for any questions, if you want photos, etc. My
apologies again for the bandwidth!

Hi everbody,

This is Phil, formerly . The email address above is my

I'm going to do the same thing I did last year, ship a bunch of tubes to
various tube dealers, and I want to again make them available here
first. Actually, I had so many buyers last time that I never got around
to sending the rest of the tubes to the dealers! Unfortunately, that
means that many of these are "left over" from last year, but there are
quite a few new tubes as well. This year, I am determined to sell most
of the left overs to the dealers, regardless of how many I sell here, so
I can free up some room in the extra bedroom! Almost impossible to have
a guest at present ...

As before, I am listing three prices per tube type, the highest dealer
bid price I could find, the AES (Antique Electronic Supply) selling
price (or TubeWorld if AES doesn't have a selling price), and a "buy it
now" price, which is usually, but not always, 1/2 of the AES price.
Tubes with a "#" sign in front of the bid price are not on current bid
lists, and have an old bid price. Tubes with no bid price do not and
never did have a bid price. All tubes are NOS in their original boxes,
unless stated otherwise (an asterix next to the tube number indicates a
used tube). I have tested some of these, but in most cases I will test
them after you express an interest in them, and then let you know the
test results along with the shipping costs, after which you can decide
if you want to go ahead and buy them. If they are sealed in a plastic
bag, or you want a huge number of really cheap tubes, I'll ask if you
(hopefully) want me to test just a sample of them. Tubes that have
already been tested have the results shown as, for example, "min =
1000/2000, GE#2 = 2000/4000 (95%)," which means this tube has two
sections, the minimum for a good tube on my tester (Hickok 539C) is 1000
for the first section, 2000 for the second section, the second GE tube
in the list tests at 2000 and 4000 for the two sections, and the weakest
section drops to 95% in the "Life Test." The Life Test drops the heater
voltage 10%, which causes most new tubes to drop to 95% to 98% of their
"Normal Test" reading. In the old days, any tube that tested 80% or
better on the Life Test was considered to have quite a bit of life left
in it, and left in the radio or TV.

I did not have time to research the prices for most of these tubes,
which is why most of my "buy it now" prices are simply 1/2 of the AES
price. If you offer to buy tubes at the "buy it now" price, then I will
immediately mark those tubes as yours if they are still available, email
you (I will also email you if they are not available), and ship them as
soon as I get your payment. If you think that my "buy it now" price is
too high, feel free to offer a price between the dealer bid price and my
"buy it now price." I will wait until Thursday morning, Oct. 13 (dang,
almost Friday the 13th), to see if anyone wants to make a higher offer
or exercise the "buy it now" option, but if you are correct about what
the price should be, then probably no one else will bid a higher amount,
and those tubes will be yours at your price. And don't worry, I will not
"play games" by telling you that someone has offered more money, in an
attempt to get you to raise your bid! If the tubes are still there
Thursday morning, you get them for your bid price. I may keep a few of
the "leftover" tubes, but most of them will immediately be shipped to
the dealers, hopefully by Friday morning.

You pay shipping costs only, no handling or packing fees, although this
means that I will want to make at least $5 per order over what I could
make by simply selling the tubes to the dealers. I will ship them using
your choice of USPS First Class, USPS Priority, USPS Parcel Post, UPS,
FedEx Ground or FedEx Air in the States. The least expensive method is
usually First Class (up to 13 ounces), then Parcel Post or Priority (1
or 2 pounds) then FedEx Ground (over 2 pounds). Internationally, USPS
Air Letter Post (up to 4 pounds, no insurance), and Air Parcel Post (up
to 44 pounds, insurance optional) are usually the least expensive
choices (by air). I have a good weight scale, so I can calculate the
shipping costs to the penny almost every time (unless it's within 1/5
ounce or 8 grams of a price change). For payment, I can take PayPal,
BidPay, a wire transfer to my bank account, a money order, or a check,
but checks need up to two weeks to clear.

I formatted the tube list in fixed width font, so if it looks screwed
up, try putting it into a reply/composition and block change the font to
fixed width. Email me for any questions, if you want photos, etc. My
apologies again for the bandwidth!
