> grounding? -what do you do?
Ignore it until it becomes a problem.
Audio amps don't "need" a ground to "work", any more than a flashlight does.
For simplicity, we use "single ended" signals...

Don't need no shielding. Especially with 550 ohm impedance. Unless you are sitting on power transformers or under a radio tower.
You have a lot of basic questions. Look: get a cheap cable, some...

Uh, he's a bit confused.
Twisted pair has more capacitance. Open-wire pair (think of antique telegraph poles) has less capacitance....

Thanks. He looks good today, but will go under the knife in the morning to find out what is really wrong and hopefully cure it. IMHO things look good, but it will be an...

To that list, add the power tubes 7189, 7591 and 8417.
Nuvistors are the old...

You clearly know your type II tapes more than I do. I picked a tape that seemed good, made the machines...

VERY odd. I do recall that Yamaha sometimes did things differently. But this quirk does not ring a bell.
The Dolby Level was a good maximum for 1980 tape. Tapes got better and...

That's one way to put it....

Arg. That can make BIG difference. And I'm kicking myself for not reading every line and getting specs myself. (Actually... you edited the post while I was...

BoyElroy: this little plan has also come up on HeadWize forums, and Chu Moy may add it to his collection of articles.
Obviously you are the world's leading expert on this plan (being the only one to...
