    I am glad to see experimenting with electronics.I see from the comments that you want to try "Tube" circuits.For your own safety I would recommend searching for 12Volt tube circuits to start.There are many purpose designed 12volt plate voltage tubes on the market, also many tubes that were designed to work with 100 to 400+ volts on the plate that will work decently at 12Volts.In 12 volt circuits you will not get hurt if you touch the wrong place with a finger.When you touch the wrong place in 100 volt + circuits you can get badly hurt either from the Voltage or the normal reaction of JERKING away.Try the low voltage first and grow to the high voltage,When you get to the high voltage remember "Always keep ONE HAND IN YOUR POCKET ", and use "Chicken Sticks"Ke...see more »I am glad to see experimenting with electronics.I see from the comments that you want to try "Tube" circuits.For your own safety I would recommend searching for 12Volt tube circuits to start.There are many purpose designed 12volt plate voltage tubes on the market, also many tubes that were designed to work with 100 to 400+ volts on the plate that will work decently at 12Volts.In 12 volt circuits you will not get hurt if you touch the wrong place with a finger.When you touch the wrong place in 100 volt + circuits you can get badly hurt either from the Voltage or the normal reaction of JERKING away.Try the low voltage first and grow to the high voltage,When you get to the high voltage remember "Always keep ONE HAND IN YOUR POCKET ", and use "Chicken Sticks"Keep at it and enjoy, you have talent in design I like.These tips from a 70 year young person that learned the hard way.Adrian "46hammerman"

    How to Bend a PVC

    Don't feel that way.We all at some time will draw a total blank on why things are done one way or another.At 70 I have had many, but at the same time I have seen easier or better ways to do things also.Everyone does.Keep an open mind learn as many different things as possible be it mechanical, electronics, cooking, sewing or anything.You will find many things overlap in how you do things.Good luck and long lifeAdrian.

    How to Repair a Microwave Oven

    9 times out of 10 if the fuse is blown one of the door switches is defective!IF one is defective replace all 3 as the one that is defective is normally the "Safety" Switch which SHORTS across the AC line if one of the other (2) TWO switches does not open at the correct time as the door opens with the microwave operating.This is from repairing microwave ovens for 25 + years.
