You have to make a decision based on how this transformer tests-out. Option 1: Step-up transformer to rectifier+capacitor. This is by far the simplest solution if the turns-ratio is in the right ballpark, and it doesn't overheat under load when running on 60Hz. As mentioned above, try applying

Thanks to all for the answers including the clarification on turns ratio. One question though, this reads as an inverter in the listing, so I was under the impression I could feed it DC in and get AC out. They reference using a 9V battery as input in the description. Is my impression correct? On

This is not the turn ratio. The person who wrote that text measured DC resistance... so 260 is resistance ratio, which is a pretty useless parameter. Both windings are most likely wound with different wires (thicker for low voltage side, the thinnest possible on secondary). What you need to do

Turns ratio 260...   1 Volt AC in gives about 260 Volts AC out - without rectifyers etc.   Need to be very low on the AC in or you will get excessive HV out    states it is for devices using much higher voltage.  -- Original Message --From: John Rehwinkel Date: April 19,

Hi all- I noticed that electronics goldmine is selling compact inverter transformers cheap, so I just ordered a few: https://www.goldmine-elec-products.com/prodinfo.asp?number=G22744 Can on of my betters on the list advise on whether they see any issues with using this to test a NIMO tube using a
