Looking at my PayPal invoice it says...
Merchant
ALIPAY US, INC.
I have to admit, this is all very confusing to me.
When I had ordered the tubes, I don't believe that I had seen them available on Amazon at that time.
However, I do see that they are listed for sale now on Amazon being sold via Salience Hi-Fi Audio for a higher price and with only a 12 month warranty and a return window of only 30 days.
Whomever I bought my tubes from says a warranty of 2 years with a return window of 90 days and the cost was less than on Amazon.
I did just now receive an automated email from AliExpress that they are awaiting my return shipment though. On the invoice it says GD-PARTS Audio Store.
So, I have no idea who I bought these tubes from...
Did I buy them from....
1. Shenzhen Dingwan Electronics Co
2. Cititrans - A
3. AliExpress
4. GD-PARTS Audio Store
I'm embarrassed to say that I really do not have a clue.
Best wishes,
Don
