Brod kikoman46, yes i'm in Dubai right now working in a coffee machine supplier as a technician, I already tested Mr. Apex B500 and it had a really good sound but the H900 i haven't test it yet due to spare parts is not available here in Dubai, but as you noticed the circuit is just the same, an additional step driver for h900 was added. the parts which is hard to find in the Philippines are the following: BAV21, NSL32, IR2117 and all other parts are available. but as what i did i ordered it from farnell through element14 there is a distributor there in the Phil., or you can ask Sir Irvynejay or Engeldelapenia maybe they can help you with the parts you need.
