Kuba, It is simple, very few newbies can afford to buy top dollar calibrated equipment. I have had the luxury of living near a surplus dealer that literally has gone through tens of thousands of

because of modern technology you arent paying very much for all those modes the software programming is amortized over a tremendous number of units

They have different IF frequencies. The TR502 matches the 7L series analyzers, the TR503 matches the 49x series.

The title says it all. How are the TR502 and TR503 tracking generators different?

Interesting note, I was using the BNC connections. I also noted that I had some ground noise, and at really low output levels, sometimes the desired signal would be swamped by line current. But yes, I

Couple of bullets for yall. As I'm no RF engineer or even purport to know much about what goes on inside a tuner, I rely upon service manuals! Wow, I bet most of yall are saying jeez. Anyway,

From: "jones_chap" <jones_chap@...> [snip] Interesting note about "anything with banana plugs" is that when playing around with the AM501 plugins was a sensitivity of the output based upon the

customer dosent want to pay for complicated Tell the Japanese TV, VCR, and cell phone designers that. My TV has more programming modes than a 757. 8=)) -John

Thanks. You beat me to the second question! I did wanna know if I could "upgrade" knowing that better op-amps exist. I've downloaded the book and will check it out later and added the site to my Audio

My late father used to say "Why do it simply, when complicated works well too" (It looses something in translation) He also said "An engineer can do for two cents what any fool can do for $10.00"

Hello, Anyone have spares I have a way to test. I have three new 1000uf tabed radials that have been tested and work in 465M, and one old style 1000uf OEM tested. I also have one old style 18000uf

Er, guys, do you even know what you're arguing about? The discussion has degenerated into everyone saying this: for a noob, buying an unknown 7603 and having no access to equipment to properly test

I mean IF of course. Kuba

I don't have the clue what you're talking about :( Kuba

The input will look like a square wave even with a badly nonlinear vertical channel. The output "square" wave will then typically be much slower than the input one you fed to your system. With

I was talking about "aligning" audio circuits, e.g. adjusting operating points of various stages, checking response, etc. Not about any sort of RF work. If I wanted to see a nonlinearity of a stage in
