Not to be painfully obvious but there is no hope of them getting a refund to put the $ into something else if they can't get in touch of anyone at the company...
I have a feeling that the reason many folks are getting replacement power supplies (besides the fact the the factory unit is such an incredible PIA to work on) is their supply is either dead or dying.
Eventually that mains P/T will go then it is a boat anchor. There is no replacement available and the cost of having one made is well beyond what anyone is asking for their version replacement supply. They do go, in my 20 + years servicing these I have replaced several bad P/Ts, back in the days when they were still available.
There are problems with the factory unit design, the audio secondary voltages are around 60%+ too high causing the regulators to work way to hard.
Ever wonder why the fans are blowing out so much heat?
I imagine this was an effort to make it work anywhere on the planet with AC mains way out of spec, but in the 1st world it just makes the supply fail often.
What I have done for some clients with dual supplies is to replace the factory P/T on one of them with a properly rated 20/20 volt secondary P/T (instead of 40/40 like the factory P/T) that just runs the audio rails. There is no need for the 2nd set of other supply voltages unless your console is really large.
Then it runs cool and never fails, and you can store the factory P/T as a spare for the main supply.
But of course none of this solves the current (no pun intended) issue!
