Tektronix 921
« on: September 18, 2012, 06:15:37 am »
Need the probe for it of course. I see quite a few Tek 100mhz probes available.Will they work fine, even though this is a 15 mgz scope? I should have researched before I bought, I know.

This is the scope. Probably have to scroll down to see it.

Thanks for any advice!

Any probe will do. You may consider a 1X and a 10X probe.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Sounds good, thank you! I bet I end up paying more for probes than the scope.

Funny, I bought the same scope, a few months ago.  If you can get it for $50, it's a no brainer.  I also bought a X100 probe on Ebay for around $30.

$50 is just about what I paid. I know I won't use it "much" but it will be fun figuring it out.

I had one of those, except I think it was a 922, which is probably the dual-channel version. Scope-wise, meaning bandwidth, it's a POS, but for audio, it's just delightfully fine. And small.

This is what I use. Get 100MHz probes. I think they are $25 and work great with my Tek scope. They sell on ebay too and I think the buy it nows are free shipping.
