'DEFECTIVE' ITEMS AND 'ITEMS NOT AS DESCRIBED'
Descriptions of tubes
in our listings as having a certain 'tone' or being 'quiet' are descriptions of
that tube type in general, and not the specific tube in the listing. Tubes are
ONLY considered 'defective' if they arrive broken or shorted (no sound). Terms
like 'microphonic,' 'hums' or 'noisy' are subjective descriptions (since a tube
will perform differently in every circuit), and in no way constitute a
'defective' item or an 'item not as described'. A tube is considered 'item not
as described' ONLY when you receive a different brand or type of tube than what
was purchased. Please see RETURN POLICY BELOW.
RETURN
POLICY
Unfortunately, we have had to temporarily revise our Return
Procedure, since eBay has changed it's policy and is now actually penalizing
sellers for accepting returns by lowering their Seller Standings and up-charging
20% on Sellers Fees. With this new policy, they have also circumvented the
important communication and relationship between sellers like us and our VALUED
CUSTOMERS when dealing with returns.
As a result, we are
forced to accept returns only if you contact us FIRST for an RMA Number using
"Contact Seller > I have a question about using my item or want to send the
seller a message." Explain the problem, and we will give you return
instructions. Opening a Return Request and choosing 'It's Defective' or 'Item
Doesn't Match the Listing' may result in a 45-day delay to the return because
eBay will automatically open a 'Return claim.' As long as you contact us before
ticking some box about a defective or not as described item, we will be fair
with you as we always have, quickly refund your money for any reason, and even
cover your domestic return shipping. Thank you for your time and
consideration.
Testing – How We’re
Different
We
carefully screen all tubes we sell for authenticity, and also listen to the
tubes to judge sound quality. We discard 20-25% of tubes other sellers may call
“good,” if they don’t pass our screening standards. All pre-amp tubes are
tested for emissions, shorts, gas, and leaks on high-quality, calibrated Mutual
Conductance tube testers with line level adjustment, to tweak unit calibration
for every tube we test. And whenever possible, we include photos of the test
results of your tube so you can see for yourself. Be certain that you are
purchasing quality, premium items.
While we offer an
unconditional money-back guarantee for every tube we sell, we cannot guarantee
that you will get the same test results at home, since there are too many
variables involved with vintage tube testing, which is more of an art than a
science. (For example, differing home voltages can give different readings on
the same tube with the same brand and same model of tube tester). You can return
a tube for any reason.
Shipping:
COMBINED SHIPPING within the
United States for up to 5 tubes via USPS First Class Mail. Most packages will
arrive in 2-3 days within the Continental United States. Our stated processing

arrive in Europe within 7-12 days, and to Latin America within 7-18 days

“We Specialize in
Tone”
We strive for 100%
Customer Satisfaction and the best Detailed Seller Ratings. If you are
unsatisfied with a tube for any reason, please return it within 14 days for a
refund. (Buyer pays return shipping). If you have any problems or concerns,
please email us prior to leaving Feedback and we will resolve the
issue. |
