It is a useful and succinctly put discource. Though a single secondary makes a transformer have less leakage inductance this application for multi driver speakers makes best use of a multi tap secondary. The best multi option secondary can't be this flexible, because you have to hard wire all the se...

This half belongs here and saves me searching the Owston thread. I may get time to build a two stage passive battery (and actually heated with batteries) tube phono stage with MC lift via a Wearite transformer. Whether I manage stereo is another matter. The purpose of which is to show the entire opp...

If it lessens the pain at all I killed a 350v WKZ because I forgot for a minute what I was doing. It happens to us all. I haven't had a WKZ die which was treated right though, so people don't have to expect trouble from them. you can expect trouble from vintage PIO's, all the time. They leak a black...

Yes once the amp is in a neat box it is best not to touch it. I find you need all elements visible and touchable by voltmeter probes when experiementing. Once it's in a box you can only reach some of it but never enough of it. I was thinking about using your Ant's box he made me. but what I will pro...
firstly remove the cap (if not just a stupid connection). Since it only decouples the driver from the output stage. So with the cap removed the voltages should go normal (if the dropper resistor is intact after your abuse of it.) the buzzing is the inductive components due to the extra current pulle...

I use Ubuntu 100% of time these days. It is much better for the amateur than it ever was. Far superior to a junked up Windows, and a little better than a fresh windows install. I don't like Wine though. But I am able at least to use TDSL in wine so I have all I need that must use windows. There are...

At our family gatherings it is my daughter 17 and sister in law who run the verbals. Though there are 5 males and 2 more females ig is quite clear if we start a thread we receive a witherig look and our thread is quickly hooked by an alpha female taken out of the water and left on the bank to dry up...

As I understand it, the real difference lies in the physics of the phase change (group delay?) the filter imposes upon the signal..... Using an L and a C the two effects, leading and lagging, are balanced so neither current nor voltage leads or lags, the upshot is a constant impedance for the drive...

Yes, I agree the low impedance RC networks seem to sound better than the high impedance ones, though as yet I am unsure if that is due to the network or the choice of valves used to drive them. However I (and others) think the important point about the LCR topology is that the network is a constant...
