Analogue electronics is an art of its own and a very important technology. Wireless tech relies on this so it might be a 60 year old unit but its still used similarly in commercial environments still today. There is sometimes no other way around achieving a certain solution without the use of these principles. Sealed modern plastic suppressors are very dangerous but used in virtually everything today instead of the use of soft packaged suppressors that crack and vent safely as used in this unit.

I almost thought that he was going to kill her at some point...........

there is nothing inherintly wrong with point to point. Nothing ever proven good or bad compared to printed boards. Wiring will play a part at times, but rarely. Also proper shielding is essential and routing planned well if doing point to point,. Otherwise, it's not stupid, just different, unless you are saying Audiophiles are stupid because they pay 5x more for that method. Yeah that's fucking stupid. Ijust found your channel..sweet! I had a similar device, but was Mono with Telefunken tubes

Gret vid with some good bits of info.

I plan to hook a bass up to one

I recently heard an amplifier designer say that speakers "kick back" to the amp when they vibrate and that tubes react to that at the output stage, but transistors don't and that's what makes the two types of amps sound different (hi fi amps, not guitar amps)

haha, people dont like being told how stupid they are! great vid!

[cseko85]

its one thing if your geeky ears can't hear the difference between amp and amp, (I can imagine what kind of music you listening to anyway), but why u have to be such a smartass on people just because you dont understand what's good in a point to point wired amplifier. I don't know what's good in taking old crap apart. You are just ignorant.

[DimitrisZS]

So only stupid people are buying point to point wired amps…Properly layed out, a point-to-point amplifier is a work of art, and is virtually indestructible. Search a bit around internet you idiot before starting making bold comments..

You are an ignorant. An example of luck of culture in our cheap era..

@adrs2 what's more audio perception in your ear varies. When there is a large peak in sound, stapedius muscle contracts and dampens the vibration of the stapes! That's the trick, your ear is a compressor, which switch on and off partially when you listen to music. Dynamic - max headroom solidstate music distorts your audio perception. That's why partial TUBE OVERDRIVE IS SUPERIOR because it relieves your ear! THE MOST IMPORTANT PART IS HUMAN, not your EQUATION, unless you are a robot.
