I just want to second Tom suggestion to get some good, cheap modern probes. I have both original Tek probes, and a few sets of cheap Chinese probes from Amazon. The cheap probes work perfectly well, with the exception of not having the readout pin, so you need to do the math in your head, and they're so inexpensive that you don't need to worry about damaging them.
I specifically ordered probes from AST Labs and AUTOUTLET and have been very happy with them. I use them any time I'm doing something that I know might damage my probes. The AUTOUTLET probes are rated to 100 MHz and cost $20 for a pair. The AST Labs probes are rated to 200 MHz and cost $21 for one probe. AST labs also sells a pair of 100 MHz probes for $14. There are also 100 MHz and 200 MHz probes from Hantek, at similar prices, that I would trust as they make a pretty good line of hobby level digital oscilloscopes.
You can also buy original Tek probes on eBay that would match your scope and have readout pins (either P6065 or P6105 are what would have shipped with your scope, but there's also the P6062 that is a switchable 1X/10X probe and should also work with your scope). You should be wary of any seller that tightly wraps or folds the cables, however, as that is a sure way to damage them. Look for the cable to be coiled in a loose circle and not secured too tightly. A good price for such probes is under $40 (before shipping); anything more than that and you could just buy brand new probes (with readout pins) from Cal Test or ProbeMaster.
