Looks like the caps are 10mm diameter with a 5mm lead spacing.  Height is around 20mm, but there is plenty of room for taller ones if needed.

I'm getting these for replacements:

People shouldn't have to pay for replacements or have to fix an new product themselves. it should work perfectly from the box.  i'm very concerned i'm still waiting to receive my batch 1 prosperoX-1s ordered in Dec, and the number of posts from people claiming they received broken sub standard units is unsettling.  
Its bad enough the delays and being forced to accept an obsolete product, but something that doesn't even work or raises questions if its even safe to plug in and leave running and not going burn the house down or blow a fuse while i sleep...  Sad

We are running 10 Prospero X3 in our data center (20 units of 1Ths) and so far stability is quite bad. We have to reboot some machines every few hours, and one unit is not functionning at all already. Instead of having a theorical 20 THs, we average 16-17 THs / day (we don't have 24/7 presence to reboot machines all the time, nor have auto switching plugs).

If you're changing caps, make sure the replacements have low ESR/low impedance and decent current capability. Incorrectly specced caps will either not perform properly, explode, or both. The Nichicons linked above look like a pretty good bet. If you want to test the ones you take out, buy one of the cheap (but excellent) LCR meters from eBay.

In other news, I've finally received shipping confirmation of direct-from-BA order #8xx (paid mid-November) which is an X1.

No idea why it's not functioning all X-3 i tested were running for week without performance drop and above 1TH/S per case.
Also there is a problem with 1.8 update as i heard, that causes problems to X-3 makes them run not at full spec. Better not update to v1.8 and if you did wait for v1.9.
You can also check PSU for the ones that stopped working, looks like there has been some problems with original PSU supplied with X-3.

X1 doesn't have hardware voltage control like X3, and they also don't display Watts  and Volts on their web interface (or LCD).
There is some limited software voltage control through SSH, but only allowing you to step down the voltage, not increase it.

They are bleeding for money!  They will be gone soon.  So many useless parts since they can't build a miner that they are hawking them onto everyone else.  Don't buy that shit!  Even if it is a little more expensive, go with their competitors.  Help put a nail in BA's coffin and stick in the ground where they deserve to go.

Hard to get rid of parts when you can't build a working miner I suppose.

I have to agree. Go with the competitors!

I think getting your unit converted to chips and sending to technobit is a better option. If your BA unit dies do you trust them to repair the unit?  Will they even do a repair or are you sol. Do you think they will be around in 6 months? I think technobit will be around alot longer than BA.

They have plenty of money, they're just running out of money that they don't want to steal. I have never to this day heard a single report of a customer having paid BA directly in bitcoins having seen their payment ever leave the payment address supplied by BA.

Certainly true for my payment - I have received a shipment, but the btc payment is still just sitting there...

Thats true, you are very right.  Although given their high IQ level, I would wager a guess that they lost their private key and can't access those coins anymore.  Smiley

That would be the funniest thing ever.

MinerSource did me wrong. This is completely scammy of them.


TLDR: Request cancel, cancel confirmed, offered store credit, told i cant use store credit, told i have to wait longer for refund, inquire about refund status,
no longer can receive refund, item shipped against my wishes.


* July 2nd, I send a cancellation request to support.

* July 3rd, I receive confirmation of my cancellation from Dan Murtha and inquiring if I would accept
store credit.

* July 3rd, I inquire about some items that I could purchase using the store credit.

* July 7th, I receive the following from Dan Murtha:

I apologize we did not get to your refund before Black Arrow began shipments.
Now that black arrow has commenced shipping and our first bulk shipment is on its way,
we will not be offering any more refunds or store credit until shipment of all outstanding
orders is completed, if there is any continuation in delays or defects with the products we
will continue doing refunds in the order requested.

* July 7th, I send the following:

I don't understand, I put in the cancellation request prior to shipment and I have acknowledgement
from you that I have been placed in the cancellation queue.

* July 7th, I receive the following from Thomas Salvatore:

You are still in the queue, we are just informing you of the current status.

* July 7th, I send the following:

Ahh, does that also apply for exchanges?

* July 7th, I receive the following from Thomas Salvatore:

We will no longer be offering exchanges for store credit.



At this point, I am very annoyed but no big deal I can wait until later for refund.



* August 1st, I inquire about the current status of my cancellation


* August 2nd, I receive the follwoing from Thomas Salvatore:

Thank you for contacting us and for your patience while we worked out the shipping dates with our
supplier. We have done our best in a challenging situation to deliver your order as quickly as
possible, and are pleased to report that your shipment will be released for delivery between in the
next 1-3 weeks. We appreciate and acknowledge that the wait has been longer than you had hoped. We
have reviewed your request for a refund, but are unable to approve the request. This was a “pre-order”
of mining equipment which, according to the terms of purchase posted on our site when you placed your
order, is non-refundable if cancelled. Those terms located at http://minersource.net/pages/contact-us,
explicitly notified buyers that delivery dates were not guaranteed, and that buyers should not rely on
them as a factor in making the decision to place an order with us. Nevertheless, we recognize that this
has caused inconvenience, and have worked with our supplier to add additional compensation units to your
order, free of charge. These will be included in later shipment, to be sent to you after shipping of all
orders has finished, free of charge. Again, we are sorry that this order took so long to fulfill, and
encourage you to contact us with any additional questions.

* August 2nd, I reply with:

I dont want the order I was inquiring about my cancellation.

* August 4th, Dan Murtha responds with:

Thank you for contacting us and for your patience while we worked out the shipping dates with our supplier.
We have done our best in a challenging situation to deliver your units as quickly as possible, but understand
that you have now decided to refuse to accept delivery. While we appreciate and acknowledge that the wait has
been longer than you had hoped, this was a “pre-order” of mining equipment which, according to the terms of
purchase posted on our site when you placed your order, is non-refundable if cancelled. Those terms explicitly
notified buyers that delivery dates were not guaranteed, and that buyers should not rely on them as a factor in
making the decision to place an order with us. We encourage you to accept delivery of your pre-ordered product
because we are not approving refund requests at this time. We recognize that this has caused inconvenience, and
have worked with our supplier to add an additional compensation units to your order, free of charge. These will
be included in the shipment sent to you. Again, we are sorry that this order took so long to fulfil, and encourage
you to contact us with any additional questions.

The next day I leave town for work. I came back yesterday and find that my X-1 is scheduled for delivery 8/22. Not sure what to do,
if I refuse it I don't know how I will be able to go after them for my funds since I paid in bitcoin.

If you have proof that you requested your refund prior to them shipping it to you then I would refuse delivery. There are laws in the US that protect consumers from receiving unwanted merchandise. If everyone who requested a refund refuses delivery they will have to do something about it and they won't be able to sweep it under the rug.

And on top of that, MS is going to be paying all those extra shipping costs to return them. They're really shooting themselves in the foot here by not communicating.
