Ok i'll find something. Another reliable shop is Prominerz in Switzerland. I bougth some miners there to in 2019, i donnu their ability in spares, maybe on reguest as service?
You lose nothing if you contact them, it's just doesn't line up perfectly, Switzerland and mining don't seem to blend well, I mean who on earth would start a mining business in that expensive country? were prices near the reasonable back in 2019 when you bought the gears? I think what you should look for is a supplier in Eastern Europe, mining there is a thing and probably the supplier's option is much better on that side of the continent.
I agree that Switcherland is a odd place for a Crypto miner outlet, but on the other hand crypto have no borders no time zones. Back then it was one of the few reliable outlets in Europe. They mainly profited on antminer customers, that either missed out on ordering or got to few from Bitmains batches,and saw crypto prices surge. I think prices then was like 25% higher compared to Bitmain, but i was able to buy excl. VAT. got some z11 there. From my point of veiw, ordering, paying in advance, from a Swiss company, on wich i could get info on the net and so on, contra an Asian company (ex Bitmain) was no brainer
But idont agree on that eastern europe, should be a more reliable and/or convient, chances to be scammed is in my opion higher in east EU. In general (not crypto bussinessin particular) It still carries a shady reputation from the past. Corruption is higher (maybee not everyone will agree with but lif its out of topic i'll remove it) But on the other han eastern europe is expirienced regarding crypto, land got a larger crypto community then in west, mainly becuase of the historical mistrust towards gowerments, insitutions and banks.
In some west Eu countries, like Sweden, knowledge about crypto, in mainstream population is almost non existing.
Sorry for massive of typos, but tired lika dog, becuase of a rough day, tuning all the miners to a maximum. Unfortianly i went one step to high in the auto tunning, and in the end i blow the main fuses, 4x80amps, supplying the farm, then i just threw in the towel and went home.
