Yamaha HX-10000 phonostage, any views?

I could not think of what it utilized that was non-compliant, except for lead in solder.  Their phono stage was NOT battery based; it had a massive separate power supply.  Maybe ROHS was an excuse for ceasing production, for all I know.   I wish I could hear one today and compare it to some of the better phono stages on the market.

I own gear that is built using some very old vintage parts, such as 80 year old input and  output transformers.  Although these are not subject to high temperatures so it is doubtful that they have PCBs in them, I would be concerned if they start to leak.  Fortunately, I don't run mercury vapor rectifiers.  The builder who made my preamp and power amp does build stuff with such rectifiers; it looks nice (beautiful soft blue glow), but I would worry about an accident with those things.

I built a pair of Williamson type amplifiers with Acrosound OPTs, using MV rectifiers, simply because I like their "sound".  I don't use the amps any more and was thinking of disassembling them to sell the Acrosound OPTs, but I don't know what to do with those MV rectifiers.  I've got maybe half a dozen of them, type 83 as I recall. Maybe I would give them to a trusted tube seller or dispose of them in some acceptable way.  But they sure looked cool in the dark. Don't you think 80 year old transformers are likely to contain PCBs? Maybe not if they're audio outputs.  I recall visiting the Futterman "factory", which was realliy one or two rooms in an office building off Broadway in NYC. Julius Futterman had new power transformers hanging on a clothesline of sorts to dry out, freshly coated in PCBs no doubt.

Probably someone else built the Connoisseur for Lyra, and their relationship broke down, which was the real reason for discontinuing. Thus are legends born.
