Speaker drive unit replacement.
 
Hello,
I'm after a replacement drive unit for a Technics PX20 electric piano and am
not getting very far with Panasonic. They have told me that the part number
is EAS16PL403A and that it is no longer available and there is no
replacement part. Admittedly the Piano was bought in 1989 so I'm not
surprised that they don't have spares.

Does anybody here know of a replacement that I could try (I'd obviously
replace both not just the blown one)?

Alternatively what details do I ask Panasonic for regarding the
specification of the speaker?

Full range or not?
Impedance?
Size?
Sensitivity?
Anything else?

Thank you

YOU have got two example speakers and so YOU know the answers to your

The folk at Panasonic spares have no examples and hence no bloody idea.

We have no idea either for the same bloody obvious reason.

I very much doubt it uses anything fancy, so it would be more of a
question of getting something that physically fits. The power handling and
impedance are probably marked on the speaker. Or the power output of the
amp given in the handbook.

http://www.wilmslow-audio.co.uk/

would be a good start for a replacement.

Thank you Dave,

I'm fairly sure it's a 2x40 watts RMS amplifier but we haven't found the
handbook yet.
The piano is in everyday use so I was hoping that Panasonic would be able to
tell me the spec of the speaker before I dismantle it.
I shall open it up and have a look.

Thanks for the link.

Hello David.

I am not familiar with the Technics PX20 but have had a similar problem
with a Roland stage piano, that is used professionally at 200 concerts a
year. The pianist uses the internal speakers as his own stage monitor, with
the line level output going to the PA mix.

He complained of a "fuzzy" sound. I took the speaker out. No direct
replacements were available from Roland. It was a smallish eliptical,
stamped 10W 8 Ohms, so I bought a pair of 8 Ohm replacements from
a local component shop, which had half a dozen different speakers, all
of which would have fitted perfectly. I took the salesmans' advice,
and bought the best built with the heaviest magnet. As it turned out,
it was not the most expensive. The manufacturer was, IIRC, Monacor.

This was 6 months and nearly 100 concerts ago.
All is well.

Iain

Speaker 1 = 16cm 8ohm
Speaker 2 = 12cm 8 ohm
Speaker 3 = Horn tweeter 16ohm.

It does mention that there are Stereo Left and Right audio outputs on

Erm... You now say *assuming* it is a speaker. Whereas you initially said
it *was*.

What are the actual symptoms, and what makes you think it is a *speaker* as
distinct from, say, a broken wire in the unit or a blow amp (or its fuse)
or various other possibly problems?

I'm not 100% that it's the speaker but it sounds like a bass drive unit
fault. It buzzes at certain frequencies. The drive units still work. I'm
not sure how to diagnose what it actually is without replacing various bits.

I'll have a listen tonight to see if I get a better idea.
How would I tell whether it's an amp or speaker problem?

When I design a sprinkler system, the company I work for designed the system
as I work for them. The design belongs to the company that I work for and
all of the drawings and calculations belong to them.
Is this different at Panasonic/Technics?
I was unaware of this, if it is so.
Just out of curiosity, what makes you think that I spoke to the spare parts
department?

The 'buzzing' you report is useful as a symptom. It rules out various
things which other behaviour might have caused. The speaker being damaged
sounds plausible, although it might perhaps be something else like a poor
connection rattling or a loose wire against the cone.

If you'd said the speaker had fallen silent, then it might have been a
broken connection or an amp or channel fuse failure. 'Buzzing' might still
be the amp. But the speaker is a better bet I'd think.

I'll have a listen tonight to see if I get a better idea. How would I
tell whether it's an amp or speaker problem?


If the unit is 'stereo' (has two sets of speakers and two amps in this
case) you can check by swapping over the connections so that which amp
drives which channel is swapped. If the symptoms stay with the speaker, it
points to a speaker problem. If they follow the amp, an amp problem.

However the 'buzz' does seem like a speaker problem.

You might find it is a loose wire that can be reconnected or moved to avoid
it touching the cone of the speaker. You may even find that rotating the
speaker top-bottom will help if the speaker unit has 'sagged' under
gravity. If there is no obvious mechanical damage such experiments might be
worth a try. If they work, good. If not, you are no worse off for trying.

Slainte,

Jim

He told how he too had removed a suspect speaker that

had done.

As he took the speaker out, something that had been
wedged between the cone and the spider, fell to the floor.
It was a nickel-brass threepenny bit, of 1953 vintage.

One wonders how it got there. It predates
the piano by more than forty years.

Alas, that means I can't do a joke about "at that point, the penny
dropped". :-)

Ghost in the Machine? 8-]

Or maybe a passerby throwing an old coin into the piano thinking of the old
'prepared piano' works. Do you think those with a preference for 'period
performance' would argue that coins of the vintage of the *composition*
would be required even for an electric piano?

I know little about numismatics, but I wondered which was worth more,
the coin or the piano-)


Our piano is a 'pianola', alas with the mechanism in something of a mess
due to all the rubber, etc, perishing. I think I have some thrupenny bits
somewhere. I've assumed they aren't particularly valuable, however I'm no
numasmatist, either!

That said, I seem to increasingly confirm my own view that we find
'history' more interesting as we come to recall being present for more of
it. Hence the page I put up recently on Concorde 001 and the 1973 Eclipse.
Which *is* slightly on-topic here. I used a Revox A77 as the data recorder.
I still have the tape, but not the recorder. :-)

Take a careful look, Phil. There is no such
gap above the keys on a Roland stage piano through
which a coin could pass. The threepenny piece was quite
a thick coin.

However, removing the note stand reveals that it
fits into two slots reminiscent of that on a money box.

Insults and stupidty snipped.
It's a pity that rational discussion is
beyond you, Phil. You might learn
something:-)

** The keys move, so there is a gap enough for a small coin.

It predates the piano by more than forty years.



** So ****ing what ?

You idiot.

It was a nickel-brass threepenny bit, of 1953 vintage.

The UK change to decimal coinage was Feb 1971, and of course a '53 coin
could well have been in circulation up until then.

Main use for those coins was checking the idle on the Bentley I once
owned. When in good tune, you could balance one on the engine. ;-)

At one time, it was common to find speakers in a cloth bag - presumably to
stop foreign objects getting into the works. I have ceiling speakers in
the bathroom and did just that with them - the back of them is open to the
roof void. And I do like the bass end from a genuine infinite baffle. ;-)

Take a look at a Roland stage piano, and then at the
thickness of the thrupenny bit. The keys pivot at the
back, so even though the front edge of the key drops
by 10mm, the rear of the key and the very narrow gap
between it and the case, does not increase enough to
allow a coin to enter.

Furthermore the horizontal space, even between the
E and F keys and B and C keys which have no black
keys between them, is certainly not wide enough for a
thrupenny bit.

Thought as much. Try looking it up - as you're so fond of telling others

The threpenny bit is one of the thickest coins ever minted. It also
has twelve sides, so it is one of the sidiest coins ever minted. It
doesn't fit down small slots.
