Re: Muti-tap Output Trannys - best tap to use?
That “Texas” guy used to also write for VG magazine. He makes some surprising blanket statements at times. Some are just wrong (or typos.) My favorite is when he recommends “upgrading” the main filters in vintage (tube rectified) amps to colossal levels. “..they’re so under filtered….go with 600u….....

Computerized "Scope"
I'd like to get a scope but I know little about them. I did a search about a year ago and noticed that there seemed to be no scopes that utilize the computer screen we all already have. Are there any? Do/would they suck? Is there a reason to not have the display, say via a USB connection and softwar...

Re: No grounding on electrical installation... sugestions!
One of the purposes of the ground terminal, in the USA at least, is to provide an alternate path for the current to return if a hot lead touches a “chassis” thus tripping the breaker at the panel. Without the ground terminal, the chassis could be hot here. In the USA, the neutral buss is often conne...

Re: Current direction?
Parent always told kids that your legs will cramp if you swim soon after eating. In school they told us that touching a bird nest will make the parents stay away and the babies will die. In addition they talked about some special type of stupid theoretical water (forget the name.) They also said the...

Revelation
I have often stared at the LT PI trying to understand how it makes the grid of the “2nd” triode negative as the “1st” is going positive (and vice versa.) And the answer is that it doesn’t. :o Rather, the (coupled) cathodes going positive with the “1st” grid makes the “2nd” triode’s current reduced s...
