David, I sent you a PM.

Ok, I sent you an email.

Please note that these are not unused. They were used for few days but they all are in perfect working condition. Currently, I have only 2 connected for Demo purpose for this sale.  Other 12 are not being used since I don't have any spare AMPerage left after I hooked up Baikal X10 + Giant Bs. I can test it for you before you buy one.

I have for sale 14 12  10 Bitmain Antminer L3+ 504MH/s,  and 14 Antminer APW3++ PSU 1600W.

I will also be selling surplus Baikal X10  & Giant B after completing L3+ sale. Priority will be given to existing L3+ buyers.

Antminer L3+ $1700 Each (without PSU)
With Antminer APW3++ PSU $1850
Please note that APW3++ PSU does not come with a Power Cord due to too many connector variations. You will need C13 on the APW3++ side and NEMA 5-15P (for 120v socket), NEMA 6-15P (for 240v socket), or C14 (for PDUs) . Sample cords:

These L3+ are from Dec 2017 batch but I have not been using them since Dec/Jan because my electric panel was maxed out after I hooked up Baikal X10/Giant B.

Located in Pleasanton, CA, USA. Local pick up is OK and you can test them before you buy them.

For payments, will use Escrow.com https://www.escrow.com or Forum Escrow https://bitcointalk.org/index.php?topic=2439910.0.
Buyer pays Shipping and Escrow fee.

I have one Bitmain Antminer L3+ running so you can see the revenues for past few weeks:

You can see the payments in BTC at:

They are all dust free and tested to be in perfect working condition.
Unlike Baikal, Bitmain Antminers can be easily overclcked from Admin page to vastly increase revenues.

I test each unit before shipment to make sure they are fully working.
Due to the nature of Cryptocurrency Mining, I can offer replacement but no refund. Each unit will be shipped with a unique sticker which if peeled/removed will void any replacement. Each unit has a unique MAC/SNOs that will be used to track/identify each shipment.
Buyer has 24 hours after delivery to test or troubleshoot with seller before funds are released to seller.

Please note that I paid lot more than amount listed on invoice because Bitmain asked BCC payment, but Bitmain's BCC/USD conversion rate was much lower than the prevailing BCC market price. I had to pay additional shipping/Import duty.

Kindly PM with any inquires. After initial PM, Skype and Email is possible.

Perhaps you forgot to update the Start IP / End IP addresses to reflect your LAN settings (eg., 192.168.0.0 instead of 192.168.1.0) on the Scan window. Also, select Append option before you Start the scan.

I had a similar issue of dead chips but power recycling fixed it - disconnect the power supply, wait until the fan stops, reconnect the power supply.
