Common, General Purpose Resistors

Notes:

For 5-band colour coded resistors, the first 3 bands give the resistance digits:

Black=0
Brown=1
Red = 2
Orange =3
Yellow = 4
Green = 5
Blue = 6
Violet = 7
Grey = 8
White = 9

..the 4th band gives the multiplier:

SIlver= 0.01
Gold = 0.1
Black = 0 (no adjustment)
Brown=10
Red = 100
Orange =1,000
Yellow = 10,000
Green = 100,000
Blue = 1,000,000
Violet = 10,000,000

.. and the fifth band (after a small gap) gives the tolerance (ie: manufacturing accuracy)

SIlver= 10%
Gold = 5%
Brown=1 %
Red = 2 %
Green = 0.5%
Blue = 0.25%
Violet = 0.1%

So for example, Red Violet Black Black [gap] Brown = 270 Ohms @ 1% tolerance

1.65K Resistor - Toastrack AY-Beeper Balance Mod

When using a SCART lead with the Spectrum 128, the audio level of the AY sound chip is much lower than that of the beeper from the ULA. Replacing R115 (just left of the ULA) with a 1.65K resistor gives a more equal balance.
