I ordered a pair of the older 30 watt amps from Audiomirror almost 3 years ago. I ordered them from him while he was apparently moving his business to America and he shipped the amps on his dime because of credit card issues. Vlad called after I received the amps to clarify the situation and apologized for me not being able to pay him. Vlad is definitely a stand up guy. I actually fried a switch in one of the amps.I sent it to him and he fixed it no charge. The last time I spoke with him he actually sent me a set of speaker cables to audition at his expense. I will say the transformer problem you mention has never presented itself in either of my amps and I use them daily. They still sound great and are on their second set of tubes. I would ask Vlad directly about the amps if you are wondering. He has always responded to me promptly.
Thanks,
