Just had a new experience, this page....

On my YouTube channel people keep asking me on how to use tubes and do some fancy stuff with them. But as i´m always short on time to explain/express all these things in long written words, i usually keep it short, and sometimes this leads to dissapointed readers.....Ok here is my idea:

Ask me what you want to build up and/or where you need some help , and I´ll do a specific video if I can help.

You have an old Guitar Amplifier and need some help, and you have some experience with tubes but you got stuck and need some help or hints? Jusk ask;)

You are a musician and do not have a clue what´s going on in your Amp?
You got a Tube Amp whitch nowadays producing "funny" noises?
Got a "vintage" amp with some issues and you´re not sure what to do?


You want to know some basics about Tubes?
You are unsure about:
- Operating points? 
- What´s all the odd curves in these tube data sheets mean
- Biasing?
- Why do output transformers need a load?
- Tube replacement (Specify your Amp, and/or your Tube(s)) and why you want to do this! :)



As i do not want to to bore people with unwanted rubbish, i ask YOU to ask me what i should explain;)

I have done some videos on YT about Tube (music) electronics but since I never beeing sure if it is right or not on how i´ve done it, I check this site here.

Why??

Because i´m really pissed off hearing that Musicians are "ripped off" by some "repair guys" or "technicians" who do not have single clue about Tubes at all and only want to make some fast money. They usually put some desoldered components in a clear plastic bag and tell you that they are "faulty" and needed to be replaced, even when they wheren´t in your amp, anyway!

Beeing a semi-pro musician myself for about 30 years now, building Tube based stuff for 20 years, worked in a studio for 3 years, done some pro-audio rental and repairs for 5 years. I know what i´m talking about.

I will tell you no rubbish, as I DO NOT CLAIM to know it all. When i do not know it, I´ll tell it. Simple as that!

And please excuse me for my bad english in spoken and written words, as my native language is german. So if you want me to do a video in german as well, i´ll do it;)

Thanx for your Interest, time and curiosity to read until here,

BTW:
The picture above is a Philips EL6435 Amplifier used for early PA-audio
(also known as "ELA - ELektroaktustische Anlagen" = electro acoustic setups)
delivering 140W @ 0.1% THD with 4Times "PE06/40N" High Mu BeamPowerTretodes

The picture was taken while running @ full power into a dummy load with a 200Hz sinusoidal input signal. As a 1kHz signal did not produce such a wonderful blue glow.
The tubes are not bad at all. The glow is a corona around the screen grid reflected by the tube´s glass envelope.
I have two of them restored and heavily customised to meet modern HiFi requirements and changed the Output Tubes to 807 as the PE06/40N are very expensive hard to get as well. Both are my main HiFi PowerAmplifiers right now :)
