3325b high voltage option retrofit or buy

 

Hi,

I just managed to get a 3325b for a very good price. I still have to investigate a Fail 026, but otherwise it is in a nice shape and seems to work in general.

It has Opt 1, the oven oscillator, but lacks Opt 2 the high voltage output, which would really be useful for me.

I was wondering if either some of you has one for sale (part no 03325-66508, same for the A and B model. Also I'm in Europe).

Or, go the hard way a build one. I could copy the original design but I pretty sure that some modern high voltage opamp could be used instead.
What do you think?

I have been unable to find the HV option so use a high power Burr-Brown opamp on the bench when I need it.

Check all the internal coax cable connections.? Twist and reseat all of them.? They oxidize over time.? That was the sole problem my unit had.? Maybe you'll be as lucky.
