WHERE WILL I BE ABLE
Lots of people have asked about getting
a chassis, the challenge of doing the metal work and locating all of the
parts. We have provided complete parts lists, that are up to date
(but not yet posted). From the INDEX
page, you can click on each board to see what it looks like (before and
after) along with its parts list and schematic. To view the parts
list, PC users will need an Excel Viewer. Click

If you've never done metal work before
and you want the project to come out well and not lose any fingers in the
process, here are two options...
Panel Express can fabricate the front panel. They like to work
with Aluminum and prefer to use their own stock. You should choose
an aluminum chassis because it will have the least interaction with the
transformer as Steel tends to "buzz" depending on how the transformer is
Metal Products makes rack mount boxes of various sizes. Again,
Aluminum is your choice both for minimum transformer interaction as well
as its relative softness compared to steel. It's easy to work with.
Whoever is the first to get metal work
done might consider sharing with the rest, just in case everyone happens
to use the same parts.
Service can supply MODUTEC METERS that are nearly identical
to those used in the UREI LA-4. Your cost should be well under $100
depending on condition. These meters have been pulled from Ampex
MM1200 machines that have been scrapped for parts. UREI
/ JBL can supply mounting hardware for these meters at 818-894-8850
or 818-893-8411. I have not recentl;y confirmed these numbers,
but will investigate. (ec) The Modutec mounting hardware includes
meter facia (outside trim with mounting flanges) and a pair of threaded
"T" nuts with headless screws. I will try to determine the part numbers
as they are not in the service manual. (ec)
HOW DETAILED ARE THE INSTRUCTIONS?
Scott has completed the intstructions
and I believe the actual assembly of the circuit boards will be quite easy.
You do have to know how to solder - that tutorial is my job - and though
it is not completed, I am in the process of teaching aspiring students
to solder and that has been an eye opener. I saw all of the potential
problems first hand.
The Weller WLC100 soldering iron, recommended
on my Essential
Tools page, is an acceptable iron. Set the temperature range
just above "3" (the 12:30 position), dampen the sponge with water, always
refresh the tip with new solder and use a tip cleaner if the tip changes
from its original shiney state to dull and crusty.
