There are 'never-connected power supplies' to power your Hi Fi equipment but few (if any) that incorporate the
technology into turntable speed controllers – that was until
now. We proudly announce our latest range of speed
controllers that incorporate 'never–connected power
supply' technology. We thought that ‘never-connected power
supply’ a rather long winded description
of a power supply that is completely isolated from the mains
supply, so we have decided to call it
acronym which stands for:
DC Advanced System
- which is an accurate description of ‘what it does’.
Our Speed Control Units,
as standard, incorporate a comprehensive mains filtering
system, but now go much further by completely isolating the
mains secondary voltage from the rectified and regulated DC
voltage that controls the motor speed.

Important notice : -EARTHING !!
Always use a 3 – wire moulded mains plug with
integral lead with IEC female connector to connect to the
controller, in the UK, commonly known as a ‘kettle plug’
lead. It is essential that the mains earth is connected to
the controllers to prevent electric shock.
Controllers with ungrounded enclosures can
become lethal devices in the event of a transformer
insulation failure or accidental connection of the live
supply to the enclosure. Whereas with a grounded enclosure,
such a failure simply blows the mains fuse.
All DC controllers supplied by TPA require
earthing to stop unwanted interference either incoming or
outgoing. The TPA DC regulated power supply and the TPA DC
speed controllers, have an integral LC line filter. The line
filter serves the purpose of preventing possible radiation
of radiofrequency interference (RFI) from the controller via
the power line, as well as filtering out incoming
interference that may be present on the power line.
For the filter to provide optimum performance
it is essential that the mains earth is connected.
Some Comments: -
purchased a True Point Audio PSU for my
Michell Gyrodec SE which I did after a
little research to see what was
available as an alternative to the
Michell HR Power supply. I wanted to
upgrade as the power supply that comes
with the Gyro is quite basic and I found
it to be not so stable as I had to quite
regularly adjust the turntable speed and
to do this you have to unscrew the PSU
to adjust a small screw which controls
the speed. The reviews of the Michell HR
PSU were all mainly very good but I read
that once again there was a little
adjustment to be done on the speed which
meant accessing a small speed control
screw at the back of the PSU which is
better than having to take it apart as
you have to do with the supplied PSU.
Given some thought to this I decided to
look around for alternative solutions
which is where I came across the True
Point Audio PSU for the Michell Gyrodec.
Truepoint make some mighty fine upgrades
for both Pink Triangle and Michell TT’s
and their PSU’s where plug and play with
the fabulous advantage of being able to
adjust the TT speed from 33.3 to 45rpm
or 78rpm at the push of a button with no
fiddling about with the TT belt.
Having spoken to Charles
at True Point Audio I took the plunge
and ordered the True point Audio PSU,
which was quickly delivered and you also
get to choose which colour lights you
would like on the PSU. The PSU was a
simple swap for the original one and the
belt on the TT is set on the 45rpm
position on the motor pulley and that’s
it you do not have to touch the pully
again as the PSU will now do every thing
for you. Press the 33.3 button and away
you go the RPM is rock steady and after
a few weeks the PSU and my Gyrodec
sound absolutely superb no hint of wow
or flutter from the turntable, the sound
has tight deep base and great overall
clarity and detail to the sound, I
could not be more happier. This really
is a great product and a great
improvement for the Gyrodec, which I
would highly recommend as an alternative
to the Michell HR PSU, with the key
advantage of being able to adjust TT
speed at the press of a button and I can
now also now play 78’s on my Gyrodec SE
if I have a mind to. The True Point
Audio provide a great product, great
service from Charles and I would highly
recommend this upgrade to anyone."
I've had a chance to
set up the PSU and listened to some vinyl. It's made a
noticeable difference to the sound. Every sound has more
detail to it, Very pleased with it.
Is it purely down to a
constant speed that makes the difference or something
else? I was somewhat sceptical about it but I have been
proved wrong... so much snake oil in this HiFi industry.

I would like to thank you,
for the PSU and its fantastic ease of use. My gyro has never
been more user friendly, I no longer have to move the belt
up and down on the pulley, risking the tension to be changed
and me putting dirt off my fingers onto the Belt, Pulley or
platter. A simple push of the button to select any of the
Also, it seems to have cut
the wow down, the belt tension is now constant.
Although I would never use
78 rpm, it is quiet a sight to see the deck go around at 78
rpm, which is not stable going from 78 rpm to 77.8 to 78.2,
due to the deck itself and the way it is suspended on the
springs. The 33.3 was rock steady when set, even if you
switch the unit off at the wall it will remember and return
to within 33.3-33.4 and then self adjusts back to 33.3. The
45 rpm was 44.9 to 45, and settles down after a minute or
The Michell HR has the fine
adjust screw on the rear panel, which I have to find a small
screwdriver to fit the trim pot to adjust, and remove the
unit out of the rack and then using the screwdriver adjust
the screw. Also, sometimes, just putting the HR back in
position causes the speed to change, so I have to go through
all that again.
ease of use and adjustment of your PSU is a much better
experience for me, no fiddling about to adjust the speed.
The PSU giving me better tighter sound on all aspects of the
LP, a piano note seemed to last that little bit longer, bass
have osteoarthritis in my fingers, not having to use a
jeweller’s screwdriver to adjust the speeds has been a great
help. YOUR PSU is a GOD SEND.
Just a quick update. I left the PSU on for about 15hrs,
switched it off, then back on today, it is rock steady on
45, but 0n 33.3 it drifted to 33.4, a quick push on the
button and back to 33.3, If anyone complains about that tell
them to see the old nut Dr.
The mains power is rubbish here, its
impossible to keep the power supply to
0.1 of a rpm on switching it on, it is the
same as the HR that I have, but with its push button speed
change, easy adjustment, it is worth every penny.
