Information
& Q&A below:
The
complication with PEAVEY bulb / fuses.
Most
Ebay listings have errors over wattage.
The
part numbers 70902306 & 30902306 are the same, just different vendors to
Peavey.
After
a long call to Peavey, here is a simple guide.
Most Ebay sellers are not technical and sell you the wrong lamp,
they will work BUT
not protect your HF tweeter.
The tech bit
(ignore if you like).
These are bulbs, act like resistors, negative temp coefficient, that means as they warm up
at high power and loud music their resistance increases, so helps
protect your equipment.
They all say 12V,
but different watts, why ?
Yes, the are 12V bulbs, usually sold as 5W 10W 12W 21W 25W.
The
smaller the watts = the bigger the resistance = more protection.
So
the 25W = approx 6 ohms.
The
12W = approx 12 ohms.
Shape and size
?
There
are 2 types
1)
snap in
2) leaded version you solder in.
They
are all about 43mm long (varies 42 to 44mm).
And dia is approx 11mm (or 15mm on the fatter glass tube types).
My amp has 2
fuses ?
Most
have one fuse, snap in or leaded solder in.
Some
have 2 fuses in series.
Some
have one 21/25 watt bulb.
Some
have two 12W in series (similar protection to one 25W).
