fan cooling system for your guitar/bass tube amplifier.
*This instructable requires electrical/electronics/woodworking tools and knowledge.*
***DO NOT MAKE THIS INSTRUCTABLE UNLESS YOU COMPLETELY UNDERSTAND
ELECTRICAL POWER AND TUBE AMPLIFICATION***
If you can't or don't want to make one for your self,
I soon will have them available at...
Step 1: Fan Cooling System (pics of on/off temperatures)
The Idea behind this instructable is that tube amplifiers get very HOT!
I understand that Hot tubes=Great tone!!
Although heat can kill an amplifier.
If your power transformer gets to hot, it will cost about $100 to replace,
heat will kill your capacitors in the amplifier killing your tone, and be costly to repair,
If the temp gets to hot inside the cabinet you speaker could blow, it will cost $50 or more!
So this system can keep your amp cool and save you money!!!
I have ran many tests with this system on many different amplifiers,
on average a power transformer gets to 120deg. or more,
with My fan cooling system the temp drops to about 70deg.
Step 2: Tools and Materials required
tape measure, pencil
drill, small drill bit, 2" hole saw
table saw or circular saw?
clamps, wood file, sand paper
razor knife, and paint brush
24" x 24" x 1/4" thick plywood
computer fan, electronic on/off switch, 9v battery, clip, and connector
2- 8-32 screws with washers and lock nuts,
electrical tape, U/L list metal duct tape, black paint
Step 3: Measure the back panle
you need to measure the inside of your amplifier cabinet
edge to edge, and about 1/2" down past the tubes
or you could use the existing panel cover
that came with your amplifier this also makes
a great template for the tube vent hole that has to be cut out.
