VIZ Isotap II WP-27A Variable Voltage Isolation Transformer – Tested & Working

Description

I am helping out with the estate of a good friend of mine who was a ham radio operator and collected vintage gear for many years.  I will be listing his equipment during the coming weeks and months.
Here is a nice VIZ Isotap ll, Model WP-27A variable voltage isolation transformer in nice condition.  You can vary the output voltage from 25 volts to 125 volts in 5 volt increments.  Rated at 400 watts.  This is just the thing for working on old tube radios and amplifiers and eliminates the need for a variac since you can bring up the voltage on old equipment in 5 volt increments.  It even has terminals where you can insert your voltmeter to measure the output voltage.
I have thoroughly tested this unit and it is fully functional.
I have taken photos from all angles so you can see exactly what you are bidding on.  I have also added a few photos showing the output voltage at various settings.  No manual but you really don’t need one as operation is straight-forward.
While I have described this unit as accurately as possible, please note that vintage tube gear is best enjoyed by those with an understanding of electronics and the ability/equipment to work on them.
Sold “as is” but guaranteed to be as described.  Please check my feedback.  Feel free to e-mail me with questions.
I strive to provide an accurate description and complete disclosure of the items I list. If the item does not meet your expectations please contact me prior to leaving feedback so that I may address any issues. I make every effort to ship within 2 business days of receiving payment.
I will use either UPS or USPS Priority Mail for shipping, whichever the buyer prefers.  International bidders are also welcome where eBay’s global shipping program is available.  I do not charge for packing and my packing is second to none.  Thank you for looking.
