Hang on! Didn't the uk change from 50hertz to 40 hertz to bring us
into line with europe a while ago?

Nope -- Europe's also 50Hz. We did change mains *voltage* tolerance
from 240V +/- 6% to 230V +10%/-6% to match European standards in 1995,
but in practice the mains voltage in most places falls comfortably
inside the new range already, so nothing much has changed.

Changing mains frequency would mean an awful lot of people would need
to buy new clocks...

And moan about poor performance with their hair clippers, shavers etc.

That's what I mis-remembered as a frequency change then... do people still
use ac to regulate clocks? Even after quartz came out! What is the
tolerance for the 50Hertz now then?

Thanks for the info though.... much appreciated.

No wonder this group is described as 'Audio'.
'Hi-Fi' it ain't...
...LOL

Deck was free from a mate many years ago, speakers (Pioneer twin bass
reflex, look awful but sound ok) £15 from a tat shop, amp (Sony TA-F3A) £25
from a car boot. PC (homebuilt) goes into the amp too, as does a cheap
Phillips cassette player (£20 new). Guitar, keyboard often goes through the
amp via the PC as needed. As does HF radio and VHF/UHF scanner.

I can play just about any audio, video format, listen to radio frequencies
from long wave to microwave and jam along to stuff with the guitar with
reaonable reproduction, working on the vinyl as you know, it'll get there
though. Bearing in mind that my lp's have all seen better days after many
excellent nights debauching in the dark with scratches, dust and the odd
beer spillage it's really not worth spending real money on something that
will reproduce clicks, clonks and hiss in stunning Hi-Fi....

This whole setup does what i need, I have a very small fron room so power is
not an issue really. If needed i can use DSP to fiddle about with the output
of any or all of my sources. And it really hasn't cost me a great deal. If
it goes "phut!" tomorrow i've not lost much. I never did claim it was Hi-Fi
anyway. I don't expect it for £60 worth of kit. "Recreational Audio" seemed
to sum up what I do with this kit so that's why I posted here.

Playing a 33 at 45, but slowly?


Could be... there's a vibration as well, a sort of grindy hum. I thought
it was a 50 hertz hum from the power supply but you can actually feel the
vibration when you touch the deck. Perhaps the belt has shrunk making things
very tight. I will try and work out how to change the belt. I've seen them
on ebay for £6 or so.

Your right though, seeding up is very wierd.... you'd expect an old,
perished belt to slip and give loads of wow and flutter. Not a steady
speeding up. Off to order a new belt, i'll post with the results.

Les


Possibly muck on the motor pulley making it bigger diameter and
therefore moving the belt faster. Could cause vibration too.

Although eBay is somewhat derided - (and, if I weren't in the sticks,
wouldn't necessarily be my first choice - also there's the tenner+
delivery to factor in) it's quite possible to get Stunning HiFi for
almost nothing.
The LP playback side is rather expensive, I grant, but last night was
listening to one of my systems (1983 Linn Sondek cost 160 inc
arm/cartridge - not eBay)
+ 100% New absolutely Audiophile (1982) JVC A-X5 amp- 70w+/ch - almost
400quid new - 31quid / JVC T-X900L tuner 300 new - for 25 - JVC KD-A5
cassette - 100% new - 14quid - nearly 500quid in 1980..Cambridge R50
speakers (weigh almost a cwt each..) - excellent condition/mint drive
units (new Ribbon Tweeters) 190quid in 1973 - cost me 50, all in
(could've got 'em for 30...).
You'd have to pay a small fortune 'new' for gear of that quality now
(JVC could be top quality those days - hardly saleable on eBay
though..)
My most recent cassette deck was a mint 1985 Akai GX-R88 - 25 quid -
450quid machine. The accompanying manual/huge service manual was almost
worth what I paid !

Personally, I'd look around for a Direct Drive TT (the only 'type' I
don't have) - but not the cheapie stuff...however, the state of the LPs
is a factor - as you mention.
MiniDisc is my favourite - and, yep, I've got the 'best' Sony ES decks
for peanuts - even the discs can turn up dirt-cheapie - ie; new/sealed
MD80s - recently bought over 100 for 25quid - *inc p/p*...

Further to the "getting back into vinyl" saga....

Now have it sounding great.... but it's playing too
fast. Not by much, just enough to make things sound a
tad hurried with accompanying pitch shift. What on earth
could make it play fast? It's not had a new belt for years, it's been
stored
unused for 7 years. Could this be the problem? It's the
last thing I can do myself I think without calling in

Have you put a strobe disc on it, and measured just how
fast it is going? You can download a strobe disc from

I note that Les completely skipped over this highly relevant and helpful
suggestion.

Under ac lighting the lines advance slowly in the direction of travel
meaning it's too fast I think... I may try it later with a flourescent tube.
It may give a little more definition than an incandescent bulb. the effect
could still be discerned though..

Were you serious about Pink Floyd being two frets high? That would be
such a huge error that you wouldn't see movement in the strobe disk at
all - it would be a blur. If you are seeing movement slowly in the
direction of travel, it is going to be close enough that you would
need instruments, not your ears to detect the error. Is there any
chance you are fooling yourself here?

Do you have a musical instrument of any kind that is definitely in
tune. See if you can play along to something modern in a known key.
That'll give you your answer.
