  • Like that transformer but it is a baby compared to one I picked up 40 years ago at a computer surplus sales on west Apache in Phoenix AZ.Don't know any specs on it as I have not used it yet but it has #8 Wire leads for secondary to 1/4 in bolts!dual primary for 120 or 240 Volt input using #14 size wire from 1/4 in bolts again.About 14"X6"X6" in size and about 50Lbs.At a price of $4.00 I could not let it set there and have kept my hands on it through 2 marriages. Would send a photo but it is in AZ and I am in Mi. right now.

  • Yes and it is very easy.Use (2) Two audio output transformers for transistor circuits.Connect 4 or 8 ohm output sides to the speakers.Then connect the primary side to the input via capacitor on high side and tie ground sides together.This is what we did back in the day 70's to connect to 110 volt lamps in light organs.

    It also helps to put (2) Two twists per foot of run on twinlead!This was standard practice up until coax started to replace the twinlead about 1975.Also in Arizona we had to replace the twinlead about every 2 years as the sun would Bake the insulation making it brittle and then bye bye insulation.

  • 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…

    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.

    It prevents the pipe from collapsing or Pinching as it is bent.Keeps it open inside.

  • 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.
