Figure 8. Trimming the top cover panel (side cutters will do)
Please note that the amplifier is at all times pure Class-A, and as such will run
reasonably hot.
We hope that you enjoy building your kit!!!

Upgrade options
Stainless Steel hex head screw upgrade
The stainless steel hex head screws - 16 in total are designed to replace the standard
zinc pan pozi screws used to hold the valve/tube bases to the chassis and also the 8
screws that are on the top stainless steel top plate.
The 8 screws that hold the valve/tubes bases down should be used in conjunction with
an M3 washer for optimum holding.
Tantalum Resistor Upgrade
These exotic resistors sound less dry than metal films and they do not emphasize any
particular frequency range. They sound more natural, more musical. They work
extremely well in Edison kit tube amplifiers. Most customers, who have tried the
tantalums, say that they would never go back to the common metal film type resistors.
These have a 1% tolerance.
Care must be taken in their use and when bending component legs, do not bend too
close to the resistors body. We recommend using a pair of long nose pliers closest to
the body and the bend made after the pliers.
