July 17, 201114 yr Sorry, I know nothing about the scope stuff, my friend did it for me. We only measured at the outputs, so low voltage. I am satisfied to the degree that my engineer friend said it looks good. I think he is pretty good but who knows. The amp works for now
July 18, 201114 yr TPI ADF15 High Voltage Differential Probe ebay# 310329294762 $350 buy-it-now ~$150 cheaper than Tek probe, not as good though, but maybe good enough. Maybe we should group-buy the Tek probe and share it around. I suspect that we will not often have a situation where more than one builder at a time is at the stage where construction is near completion and he needs to measure stuff. Just a thought. You can also get high voltage probes for your scope, much less expensive than these differential probes. 2,000 volt operating limit, 100x voltage scaling (i.e., 100:1) is under $30, I've seen probes rated to 10 KV, 1000:1 , also, same price range.
July 18, 201114 yr Very cool sir! If the "new" T2 is residing in your main rack, where do you keep your "old" one?
July 18, 201114 yr Very cool sir! If the "new" T2 is residing in your main rack, where do you keep your "old" one? The guy who did all the soldering on it gets to keep it in his room. He is loving it.
July 19, 201114 yr that's the jack for the Sennheiser HE90. it's available from Fischer Connectors, has to be custom ordered
July 19, 201114 yr It was like $65 a couple months ago. Tough to find a reasonable price for the thing.
July 19, 201114 yr It was like $65 a couple months ago. Tough to find a reasonable price for the thing. they're $51.10 at the 1-24 qty, and get as low as $35.26 at 100-249 qty. The price was $34.86 for 10 in 2006
July 19, 201114 yr Fantastic result Andy! The knob is awesome. Congrat! I have a vewy gweat fweind in Wome called Cocus Knobus. Do you find it ... wisible? Beautiful amp!
