<DIV><FONT face=Arial size=2>Matt,</FONT></DIV>
<DIV><FONT face=Arial size=2>I did exactly that, back in the late =
70's, (at the
request of Yamaha, I might add.<G>). It is definately the way to =
go. You
will need to change the plain wire to wound on the tenor bridge. It's =
been a
while since I've done one of these, (I've done several, al with =
excellent
results!) As I recall, the first 6 notes on the long bridge need to be =
wound. I
still have the scale data, somewhere in my 'puter cobwebs, but I'd have =
to
search for it.</FONT></DIV>
<DIV><FONT face=Arial size=2>It is not necessary to modify the =
bridge in any
way. just use the outside bridge pins of each note, leaving the center =
blank.
Also, the same for the tuning pins. As I recall, I left the "blank" =
tuning pin
in place, so that it had a nice appearance. You will have to add som =
hitch pins.
As I sent all of my schematics/blueprints to Yamaha, I don't have a copy =
of the
hitch pin pattern. It's fairly easy to figure out where they need =
to be
added. It is suggested that you add the hitch pins BEFORE ordering the =
strings,
so that all dimensions of tails, winding start/finish, will be correct.
</FONT></DIV>
<DIV><FONT face=Arial size=2>You may be able to get all this info, =
plus the
exact strings, from Yamaha, but I don't know wether they consider this =
an
"antique" piano and would want to be bothered. They do have all of the
information, as I presented it, hopefully. After all they did pay me to =
do the
research on it.<G> Since that time they used the info on their =
next
version of the GH-1 and then for some darned reason, changed it two more =
times,
(not for the better, either, IMHO)!</FONT></DIV>
<DIV><FONT face=Arial size=2>One big caution: The original GH-1 had =
little or
not support beams, so the piano is really squirrely! Remove only the =
absolute
minimum strings to access the area for hitch pins etc.! It will go 20+ =
cents
sharp when you do this! Not to worry. Once you have the new strings on =
and
tuned, the darned thing will go right back to pitch, (pre-work pitch)! =
Go
figger.<G></FONT></DIV>
<DIV><FONT face=Arial size=2>Once the work is done, you'll probably =
have to
correct the "voicing" that was previously, (and to no avail), done, in =
that
section. Once that is taken care of, you'll love how nice that =
"transition" can
be, for a small piano.</FONT></DIV>
