  • Just a word on capacitor discharge. Letting the power supply sit normally won't discharge the circuit. Most modern circuits have a discharge safety circuit in them these days at least in guitar amplifiers I've found. However it is very common for tube amps not have them for fear of sound hindrance. I built a discharge tool from a few alliator clips a large resistor and a led light. In my 100 watt peavy amplifier read 386 volts after sitting unused for 3 months. A handy way to discharge circuits that are switched is to switch the power on without power supplied. Won't work for all circuits but does on some. An ARC supply is either plugged in or not so I would imagine it will discharge itself but it is always imperative to always check the circuit is discharged. 386 dc volts like in my am…

  • Did you read the instructable or just look at the pictures. He sure did credit the original design to the above mentioned "colin" with minor changes of his own

  • You can run 7018 on ac not recommended in data sheet but there is a 7018AC rod. I would stay away from 60 series rods for something like this although the tensile strength rating is high i have found they are a very brittle weld in comparison and with all the expansion and contraction i would stick to 7018 they run nice too.

    And for DC 7018 hands down.

  • I was thinking the same thing. Some angles or radius shapes maybe. I used to be a professional woodworker for about 12 years and I loved working with veneer also cool project.
