Test Record

[OvenMaster]

Wow. I've got an Shure Era II (!) disc, and the only thing I ended up using it for is the blank anti-skating band. For everything else, I just use Grade B LPs.

I tried the new Hi-Fi News Test Record last night. It seems that, for the 300 hz anti-skate tracking bands, my tonearm can't put in enough anti-skate force to track all 4 test bands without significant right channel distortion. This is true even though I'm tracking my M97 at 2.0 grams with the stabilizer brush. Makes me sort of discount the results, really.

(And I'm embarassed to admit how long it took me to realize that you have to manually cue each track of the record. :stupid: )

shure record

hi, i have been looking for a test record... i think i saw the shure record you ppl are talking about but it had no info on it so i left it in the store.. is it a record with a yellow front cover with a cartridge on a record on it? and if so, can anyone post -or point me to- the necessary info for this record? any help would be much appreciated!

The record you are seeking is Shure ERA IV and the number is TTR-115. The one you saw was not it. It has a dark cover.

i think this is the one i saw:

is it worth picking up? can anybody give me a scan with the insert/liner notes/info since it seems quite worthless without that!

Do not demagnetize a moving magnet cartridge.

 

[OvenMaster]

That's my Era II disc. Liner notes say it's from 1967 and that it "cannot be played more than ten times with an ordinary tracking cartridge, regardless of how light the tracking force, because the high frequency characteristics will be erased by the groove-deforming action of the stylus."
Sorry, but I don't have a scanner.

nice cover design though. :thmbsp:

You cannot demagnetize a cartridge with an inert vinyl LP. It might give the suspension a good work out, but that's about all.

i picked up a 'hi-fi sound' test record HFS75 circa 1974 a while back...didn't expect much from my at95e...but it coped well with all of the 'hi-fi standard' tests...
the torture tracks for super profiled esoteric cartridges didn't seem to throw it out the groove either..with only a very feint sibilance to suggest mistracking when the going got tough..
i reasoned that any +18db 300hz lateral test tone should eject a £20 cartridge instantly...its 8 months old with about 300 hours on it tracking at 1.75 gm with approx same bias...and made it to the end of the side without fanfare or fuss...just a feint left channel high frequency buzz...that i could only make out with headphones...
if it aint broke..
a minidisc recorder set to record with no gain ( 0 db input) can help make visual and aural sense of the left right balance tests up to a +12 db signal...or reduce the record level to -6db for anything higher...

think i'll try the shure mentioned above also if i track one down in good fettle :scratch2:

Definitions

On the Notes Era 1V TTR 115 How to recognise Mistracking
various descriptions are given to help define mistracking
Two I need more clarification on are ie what do they mean?
"Stridency"
"Sputter"

Another Question I have is if mistracking is detected what are you supposed to do about it? The only advice on the Notes is to increase the tracking force within the manuf's recommendations. As far as I can tell the alignment is spot on

Thanks
