RAMSEY "LEARN-AS-YOU-BUILD RECORDER ASSEMBLY

STRATEGY"

The RV1 has a fairly compact assembly compared to some of our kits, and for

this reason it is advisable to follow our step by step instructions closely. The

reason being that if you were to install some of the larger components first, there

would be no room to get your fingers in to install some of the smaller components

later. Also while we go along, this manual will describe the purpose of most of the

parts, so you will know exactly what your kit is doing, or meant to do when you

are finished.

We'll start our building in one corner and work our way across, installing the

lower components up to the taller sized components. This will make our placing

and soldering of components easy. As we go along we'll attempt to describe the

circuit operation and the function of many of the parts.

Be sure to read through all of the steps, and check the boxes as you go to be

sure you didn't miss any important steps. Before you switch on the power in a

hurry to see results, check your ICs and capacitors for proper orientation. Also

check the board for any possible solder shorts, or and cold solder joints. All of

these mistakes could have detrimental effects on your kit - not to mention your

ego!

Kit building tips:

Use a good soldering technique - let your soldering iron tip gently heat the traces

to which you are soldering, heat both wires and pads simultaneously. Apply the

solder on the iron and the pad when the pad is hot enough to melt the solder.

The finished joint should look like a drop of water on paper, somewhat soaked in.

Parts are mounted on the top side of the board, that is the side that has no

traces or pads on it.

IC sockets - A good practice, but not necessary in digital or low frequency circuits

such as this. This prevents the horror of desoldering a bad or incorrectly placed

IC.

Part orientation - All parts in the kit are mounted at 90 degree angles to each

other, meaning that all parts are either parallel or perpendicular to the board.

Part installation - when parts are installed, the part is placed flat to the board, and

the leads are bent on the backside of the board to prevent the part from falling

out before soldering. The part is then soldered securely to the board, and the

remaining lead length is then clipped off.
