I have two Panasonic VCR's, model numbers PV-V4540 and PV-9450.

They are almost idenical on the outside and very simular on the
inside.

The "newer" model - PV-V4540 - seems to have a head going bad from
everything I've read.

The PV-9450 works fine, but doesn't have the features that the PV-
V4540 has.

I would like to install the head unit from the PV-9450 (the older one)
in the PV-V4540 (the newer one).

They look the same, but are they the same? And if I swap the
headunits, will the alignment be the same?

Here are pics of the head units. The one thing that I wondering about
is the "arm" on the center post of the (newer) PV-V4540...what is
that?

from the parts list pvv4540 uses the beliow listed upper cylinder head
VEGS0427 *( A )
VEGS0428 *( B,C,D )
VEGS0429 *( E,F )

pv9450 uses
VEHS0571 *( A )
VEHS0570 *( B,C )
VEHS0567 *( D,E )
not much help but swapping may not hurt

Given that info, it's probably not going to work right. Hifi sound is
critical of correct head performance, so if there are any specification
differences between the head drums, there will likely be a problem.

Well, that is an understatement.

Put the head drum from the older working VCR into the newer one, there
was no signal on the face plate for "HiFi".

So I put it back into the - what was working unit - and NO HiIFi.

Don't know what happened, but the newer VCR fried something in the
older ones head drum.

Now I have 2 Panasonics that don't work.
