If you do try one: be certain to replace the fuse and power
cord, with some upgraded products(ie: Hi-Fi Tuning Supreme and
a Synergistic power cord). This piece already employs fairly
high speed rectifiers and responds surprisingly well, to these
two tweaks. If you can solder, install HEXFRED or Schottky
rectifiers, Belleson regulators and WBT RCAs, for even better
presentation. The improvements are not at all subtle. Muting
& mono switches, remote volume control and phase inversion are
why I tried the unit. It takes a bit of work, to draw out the
performance. Unless you use an SUT and a very low output
cartridge; chances are, you won't experience any noise at all.
That's unless the transformer is not moored down properly.
Some users have had a problem there.
