over 73 btc in s-7’s and s-9s
not to mention

So Over 73 btc on s-7's and s-9's and at least 50 btc on s-1's, s-3's , s-5's lets say 125 btc in gear.
I had a dead s-1 damaged in transit. Yoshi and the old dz-coop replaced it via cross ship .
I had an low hash s-7 took 6 or 7 months I was given 150 usd in comp.
I have a s-9 did a thread on it https://bitcointalksearch.org/topic/how-low-can-it-run-whats-it-the-batch-10-s-9-1590910 and it details how to make a quiet low noise s-9
I guess bitmaintech had the same idea as they now have a quiet miner listing
https://bitcointalksearch.org/topic/bitmain-announces-the-antminer-r4-and-apw5-power-supply-designed-for-silence-1597639
So my miner dies one board after ten hours use. I contacted Yoshi in Colorado and shipped the board to him.
Board arrived on weds the 24th
I await news on replacement of it.
Meanwhile it looks like I have lost a second board on an older s-9 I will check it out on monday.
