| Do you get the distortion with all sources or just one?

| Also, do you get distortion if you use headphones ?
If you do (and your headphones are OK!), then that rules out the speakers.

| It seems to be when I listen to Tapes. I will check to see if the
other sources have the same problem.

The only headphones I have are a pair of 10+ year old pair made
by Boots. My bother went off with my ROSS headphones a while ago :-(

| I borrowed a pair of headphones last night (Thanks Rob) and I got
the distortion with the headphones as well. It seems to get worse
as the volume increases.
What could it be ?

| Does it still only happen with tapes?
If not, then it suggests that the amp is suspect.
As it is dependent on Volume control, then I would hazard a guess that it
is the power amplifier. Do you get this problem on tapes that you record
from other sources ?

| It is on tapes that I have recorded off of CD.

| Grant,
Here are some helpful and not so helpful suggestions !
Check that your leads are securely into the Amplifier sockets (inputs and
outputs), clean/demagnetise your tape deck heads, check the recording
level (remember CD's have far stronger signal output than albums),
clean the fluff off your stylus, and out of the headphone grills.
Borrow some other speakers/headphones.
Listen very quietly.
If all else fails......ask your Dad for a new system !

Hi Tim
Thanks for the info and unfortunatly I bought all the gear with my
own money :-(
one thing I will try is disconnecting my Equalizer from the system
to see if that makes any difference.

| 146.9 | There is new life in the system !!!!! Hey!!! | PEKING::TAYLORG | Bodybuilders do it till it hurts | Fri Mar 09 1990 20:22 | 12 |
| I solved the distortion problem!!!!!!
I unplugged my Equalizer and hey presto (Sp?) the distortion went
away YIPEE!!!!!!!!
Now how do I stopthe hum from the turntable input?
I only get the hum when I am playing records.
Anyone want a JVC EQ :-)

| Have you checked the earth connections from your record player? A lot of record
players have the two phono plugs, and also a "flying" earth lead. This connects
to a suitable terminal next to the phono jacks on the amplifier.
My REGA doesn't have this earth connection, and I thought I would have to put
up with the hum when I first got it. However, the REGA doesn't seem to need the
earth lead.
If your amplifier doesn't have an earth terminal, then try grounding the lead
against the case of the amplifier or one of the shields to the phono jack.

| 146.11 | Anyone for ground loops? | MALLET::NEALE | Ici on parle Europ�en | Tue Mar 13 1990 11:02 | 18 |
| Back in the good old days when all electrical bits and pieces had three
wire mains leads (live, neutral, earth) this sort of hum was a common
problem. The record deck and amplifier were both connected to mains
earth, and also earthed to each other, either by means of a separate
earth lead or more subtly through the screens of the signal leads. This
caused a so-called ground (or hum) loop, and the solution was to
disconnect one of the earth leads in one of the mains plugs. The "best"
solution was to earth everything through the record deck only, but a
more practical (and safe!) way was to use only the mains earth on the
amplifier and on nothing else (on the grounds (pardon the pun!) that
whenever the equipment was in use, the amplifier would surely be
plugged in).
I know that most modern equipment comes with just two-wire mains leads,
but all the same it might be worth a check. (The modern approach to
earthing equipment seems to be that the Health and Safety Regulations
simply forbid anyone to be electrocuted, and thus earth connections are
no longer required!)
