Identifying the LA-4
by Eddie Ciletti
Before purchasing the LA-4
upgrade kit, it is important to know which version you have. The
front panels are clearly different - the earlier version is black and the
later version is silver. It is also easy to distinguish between the
LA-4 - it has multiple ratio options - and the LA-5, which is internally
preset at a 20:1 ratio. Inside, you will notice that the LA-4 and
LA-5 use the same printed circuit board (PCB).
Most SILVER versions have
IC sockets - making the amplifier upgrade a snap if you don't have soldering
skills. Later silverfave LA-4 production runs do not have IC
sockets, in which case, sockets are provided free of charge. In addition,
while the blackface LA-4 does have sockets, the output amplifier modification
requires soldering skills.
While it's all very simple,
in ALL cases, included in the upgrade kit are detailed instructions, pictures
and a strip of high-quality de-soldering braid no matter whether soldering
is optional or required.
