Head Cabinet Started


A good friend of a friend that owns a cabinet shop out here in South West Missouri spent a little time and built me a really nice head. I would have not been able to do as good as job.
Thanks Ed!

Parts order #4 Mouser


AHHHH more parts. This is my latest parts order from Mouser.

Light bulb current limiter

After a trip to Lowes and scrounging around in the garage the limiter is built. When first powering on a newly built amplifier, use a bulb limiter or Variac. It will keep you from destroying some very expensive parts if there is any problem with your amp. The picture shows a 75-100 watt lamp, but I typically use a 25-60 watt to start with. If there's something wrong with an amp, it will draw too much current and the light bulb will blow. But it's better to blow a light bulb then a $150 transformer.
Variac, or variable autotransformer, is a device to vary the output voltage from a steady AC input voltage (wall outlet voltage). It can maintain a steady voltage during a wide range of load conditions, allowing for very smooth variable control of voltage.

Update

Well I recieved the McMaster Carr order in today which was several spools of hook up wire. This allowed me to put the finishing touches on the turret board. I also placed another Mouser order last night for switches, fuses, etc.....
