In the mean time I'm looking at using newer current feedback opamps, in particular the THS3491, 900MHz 500mA output.

That might make a good basis for a "hot rod" high voltage option board!  :D

That's the idea. Given one of the applications the datasheet mentions is high voltage arb gen output.
I'm going for 2 in parallel as it supposed to reduce harmonic distortion
I will have to be serious with the board layout on this one :P

I'll create a new thread when I make some progress and post a link to it here

sounds like fun!  :D

Great project, I have two 3325 but both without HV-Option.

Are the PCBs or Kit still available?

Is it expensive to ship to Europe / Germany?
It seems China --> Germany is almost "free",
PCBs, items, modules and shipping for free or 1-2 Euro.


Thank you

Klaus
 

TERRA Operative:
I haven't made any kits etc yet as Covid hit right as I was about to do so, which severely limited international shipping from Japan.

I have a bunch of files so you can order PCB's and parts and make one yourself though:
