QUAD405 at material cost!

For those who know it, this amplifier needs no introduction.
For those who don't. They can regret it! But now they can make up for their musical sound
deficiencies.
Specifications:
2X50W---at 4ohm speakers
2X40W---at 8ohm speakers
These power ratings are dependent on the supply voltage!
Supply voltage: 2X27V supplied by a Japanese sealed-cast transformer
which supplies +-37V to the amplifier boards via a rectifier with double soft-start protection.
As an addition to the circuit, a proper loudness switch can be used, which emphasizes the bass when listening to music at low volumes.
Three inputs can be selected with a toggle switch (CD, Tuner, Tape deck).
An preamplifier or tone control can also be connected to the power amplifier input.
Without these, the connection points are bridged.

What does the material cost refer to?! Calculate it!
2 boards with components = 13eFt----6.5ft/pc at Urbán electronics.
Power supply = 4eFt
Transformer (but not like this) min = 3eFt
Case = 4eFt
------
24eFt
Plus! Hardware, connectors, small items, etc.

And you can proudly display this on your HI-FI shelf!!!
