Check soldering cracks/oxidations arround power-drop resistor(usually a couple of MOhms) that is in series with LED

Check this out, heard of Altmann Tube-o-Lator ??
Yep, I also saw somewhere similar stuff but for improving data transfer environment -- a special spray you would spark arround your workstation or server is such exists and your . . .

Yep, Sorry for messin' with vowels it's UNLYTIC and the information can only be found here: http://www.electronicconcepts.ie/display_product_details.asp?29

What the Difference 20/BIT&24BIT CD Player
1. the main role here play CDs themselves despite any kind of DAC resolution. buy some well-engineered CDs and quit comparing CDs to matching records since at that time they were . . .

How do Xover works?
And the math is very simple especially if you know algebra: The capacitive reactance Xr = 1/2*pi*f*C [Ohms] where pi is circular constant f is freequency(Hz) and C is capacitance. . .

Best sound meter for setup?
I have my probably weakest link on knowlege of room acoustics or saying simply know the teaspoon out of the ocean in that field, but seing the work of one acoustic engineer that . . .

Surge Recovery - Burned PC board issue. Techs?
Sean, Your help is always appreciated! 1.Fortunately the PC-board is not double-sided and I don't have to count on the capacitance between the sides of the PC-board! Tracing the . . .

Motor for NAK 1000zxl ?
if you can mount it yourself which i'm pretty sure requires a knowlege of sophisticated nak belt driven system you can also replace belts as well. nakamichi is also located in us(. . .

What about dips in power???
yeah... use it for computer too

troubleshooting VTL puzzle.
ummm... that was a while ago: jcbtubes was right. there was a bad tube that actually is causing this 10Ohm resistor to bloe. EveAnna Manley sais that this resistor is kind-of a . . .

Tube Voltage Rating Question
Filament touches cathode and the tube is short and ready to show some fireworks with fried PCB, wires, caps

Motorized volume speed adjustment
I guess you have to play with magnetic forces rather than playing with electric ones in that case. Play with starting inductance values if such exists or try to play with two-pole . . .

Bias adjustement pots.
appreciate for interesting article! less-likely the DC-component may be from the tube amps due to the damaged trim pot since they have an output transformer. on the other hand I . . .

Connection principles
If your processor has tape loop than you can in-out eq and use the tape switch for eq otherwise you will bypass it. Same way I use Musical Fidelity X10 tube buffer

Impedance and how it effects volume??????
Z=R+jX is measured with Ohms Where Z is impedance measured with Ohms R is resistance measured with Ohms -- a constant value that does not depend on freequency. X is reactance . . .
