Soldering
Soldering is accomplished by heating the components to be soldered and allowing the molten
solder to flow onto them. Do not try to melt solder on the tip of the iron and transfer it to the
solder joint. It doesn't work.
Follow these steps when soldering:
-
Use 60/40 rosin-core solder.
-
Keep the tip of the soldering iron clean. If it's dirty, wipe it on a damp sponge to clean
it.
-
Set the temperature of your soldering iron to about 700F.
-
Melt some solder on the tip of the iron. The molten solder helps to efficiently transfer
heat from the soldering iron to the component leads.
-
Make a good mechanical connection first, and then make a good solder joint.
-
Heat the leads to be soldered by touching it with the tip of the iron.
-
Touch the solder to the leads. The solder should flow onto the leads. Avoid breathing
the fumes.
-
Remove the soldering iron and allow the solder joint to cool.
-
Note: Do not apply the tip of the soldering iron to the eyelet board any longer than it
takes for the solder to flow.
The solder joint should be clean and shiny. If it is dull looking it may be a ‘cold solder joint’
which is not a good electrical connection. If a solder joint is suspect, heat it with the iron to
reflow the solder.
Tube Pin Numbering
•
V1 and V2 are the preamp tubes. 12AY7 and 12AX7 respectively
•
V3 and V4 are the 6V6 power tubes
•
V5 is the 5Y3 rectifier
The pins on a 9-pin tube socket are numbered 1 to 9 in a clockwise direction when viewed
from the bottom. Note that there is a gap between pins 1 and 9.
The pins on an 8-pin tube socket are numbered 1 to 8 in a clockwise direction when viewed
from the bottom. Note that there is a gap between pins 1 and 8.
12AX7
12AY7
GZ34/6V6
