1000W Tube Amplifier Interference Pattern of the MV-Rectifiers

The line frequency is 50Hz - when the signal frequency is turned to 25Hz, the pulsing load causes this interference pattern through the mv-rectifier tubes. In some way this visualises the 120 degrees phase angle.
The frequency counter is a HP 521 full tube device, the noise you hear, is caused by its fan. But you can also hear the load choke during low frequency interfernce.

1000watts at what ohms 8?

[histelek]

@omfgg3tlost 8 Ohms are connected, 10 ohms would be the exact load impedance

[cassius969]

Is 1000 Watt the input or the output?

[histelek]

@cassius969 output!

[RBSGutgefahren]

Do you have a circuit fore this great amplifier?

[histelek]

no, I hope I will get one some day...

[supermanjamil1992]

I don't mean to be a jerk....but could someone please explain to me what this is and does??? I'm honestly curious as a guitarist.

[beou1980]

electronics are just magic!!!

Did ya ever wonder if these tubes are "hard" with a large voltage drop and emitting -rays? Why not get a meter and see. I used tube rectifiers decades ago, when they age, they drop large volts across them emit lots of xrays..........really. It's your health...

This is for Chuck Norris only !

[justjoe469]

what makes the tubes glow blue smoke? and flicker? mine are orange when on

[MrMichaelLenz]

Can I play guitar on this amp ??? :D

[WauliPaulnuts]

This appears to be an audio amplifier being fed w/ a low freq. AF signal. The tubes seen glowing blue are the now-obsolete mercury vapor rectifiers used to feed the HV DC to the two final amplifier tubes (the HV anode connections to the top of the PA tubes can be seen just above the panel containg the meter). The orange glow of the PA tube's heaters are also visible there.

@supermanjamil1992

a year later I ask myself the same question? maybe it's a flux capacitor

ha ha another guitarist

[Sprekitek]

I am assuming that this is an Audio amplifier?? Still, nice too see vintage gear kept in working order :)

With this I could rule the WORLD!!!!!!
