......wants to build a Tesla coil and is looking for a large transformer 16K or so.   Have any ideas?

First! No page should appear on the WEB with the word Tesla without a warning that :
    Warning!!   High Voltage can Be Fatal.

You had mentioned Tesla previously and I failed to respond, sorry, 16K ? I hope you mean Volts and not AMPS or POUNDS?

Lets see 16K amps = 110v X 16,000 A = 1,760,000 WATTS or 1,760 KW & 1760 KW X $0.22 /per KWH = $387.20 per hour to operate! So we must be talking about volts here. Please advise when Rick fires this up California will experience its next energy shortage.

The internet has a half million pages with references to "Tesla Coil" I have seen at least a hundred good designs in the last few years. I built several Tesla's in the 60's One was quite large but I can only guess at the Voltage since I had no instrument capable of measuring a voltage over about 2KV.

I do not have any transformers that are "step-up" I guess those went by the wayside when I stopped playing with Vacuum Tubes. However I do have a solution for Rick, I have lot of 24V step down transformers with multi voltage input primaries. I used this system in the Lab at the company where I worked to built an 8kv insulation Dielectric Tester. I will need to draw up some plans but this is the basic concept,

The highest standard value you can get for a "conventional iron core" transformer is about 2 to 4K Volts. Most Neon Sign Transformers are in the 4-15KV range. This is accomplished by using special wire in the windings that will not arc out. The typical output current is either 30 or 60 ma (That's Milliamps) However in order to get the Tesla output you will need have about 500ma to 1 Amp.

The approach I have always used is to "Voltage Double" until I get What I want. I use the "Auto-transformer "principal. Since this E-mail is getting way too long I should start a Page on the WEB for it. TBC

120v primary and a 16Kv, 3050va output   (so this is a 3KW +/- unit)
I = E over R  E=16,000v  I times E = 3050va so the current = .19 amps or 190 ma.
Primary power = 3050va at 110v = 27.7amps  !!! That's a lot of power!
