After looking at the circuit I decided the only useable parts from the
supply were the transformer, board and case, so I rebuilt the circuit
using low-noise 1.5A LT1086-5 reg and schottky diodes, plus caps as
recommended in LT's application notes. I mounted the reg in the centre

I think badly compressed recordings are softened a bit by MP3. In a
previous thread I noted this was actually visible in audacity when I
compared FLAC with MP3! I look at it this way. Some transient details
are missed by MP3 on a good recording - but on the positive side some
of the extreme
I remember wondering what audiophiles were up to, buying extremely
expensive home audio systems to play old vinyl records. They put
turntables in sand-filled enclosures with elaborate cabling schemes. I
wondered what they heard in that music that I didn't. Someone explained
to me that

Now the transporter is showing new behavior - freezing up completely.
It's on a very large battery UPS, so I'm pretty sure it's not line

numbers.
Which UPS?

That doesn't work either. You'd have to increase the input voltage to
compensate for doubling the dropout voltage. Same amps, double the
voltage, and you're in twice as much trouble as where you started!
Hi Sean,
Thanks for the input.

Hi Sean,

Under load (before the regulator shuts down) there's still over 11V.
That's enough to feed a 7808-7805 combination I would have thought.
The dropout would be shared among the two regulators, no? (and 3V each
should be fine.)
I'd be
For those who wanted to see some measurements. Just came across this
while searching for something else on the web. Registration is needed
to read that forum, so I am posting a link to Google cache.
Craptastic is a great word to describe it!
I'll update this thread when I've got it up and running.
