My condolences, along with the others'. I'd recommend looking for a
used Tektronix; my 7904 died (but not from zapping) and I found a very
nice little 2465 on eBay for around $200. Not quite as versatile but
the price was right.
I've used a 10:1 probe for an "antenna" on numerous occasions & haven't
had a problem. But I take care not to get it too close to the
secondary, for sure!
