My daughters's guitar amp started making popping noises. It might be the
zener chain. I am impressed with the downloadable service manual.

Well, it's pretty much well-established that I'm weird, but I find it
interesting that the French for "Power Source" is "Alimentation", which,
in English, means "Guts", more or less. (i.e, your body's "power source".) :)

I also once saw a pack of ramen with the instructions in Chinglish or so,
where they called the noodles "alimentary paste". Certainly brings up
a different image in English! ;-)

Cheers!

A zener stabilised HT supply ! Astonishing.

Alimentar is the verb for feeding in Spanish, which seems appropriate

Same in French. Alimentation has nothing to do with guts, except that
some might pass through.

I used a string of NE-2's for a geiger counter anode supply I built 30
years ago. Worked pretty darned well. Still works.

How would you crudely level 300V regulate do it at comparable cost?

The service tech told me that is where the problem might be because it is
making popping sounds. Tubes are ok. I heard about noisy zeners. Is there a
good brand that is not as susceptible to this behavior?

Kring Hell.....

I'd be inclined to break the circuit diagram down into functional blocks and
do one of them there top down documentation things. Having said that, if the
designer knew his circuit then it does look like he/she has spent a bit of
time wrestling with stuff to give you a bit of quality.

Wouldn't be Vutrax now?

The 300V looks like it supplies the low level stuff and.......

Oh Crap!!!!!

This is part of an Eeyore Thread.


You want to watch yourself.

Chances are.

1) Someone else designed it, fucked it up, he ripped it off and fucked it up
worse.
2) Someone else designed it, he ripped it off and fucked it up.
3) He designed it and fucked it up.

Do NOT under any circumstances attempt to enter into a meaningful discussion
with this person.

All technical advice will be rendered into an 'impressive' presentation that
will demonstrate to the less intelligent people on the planet that Eeyore is
the main man and.......

He will **** it up again.

Hey, it's audio!


** No it is not "audio" in the usual sense of that term.

Musical instrument amplifiers are sound ** creators ** - so a form of
electronic music instrument.

The industry title is " stage equipment " as distinct from PA, recording or
broadcast equipment.

** Well - it isn't and so it isn't.

The 300 volt low current supply is regulated by a series pass transistor.

The zener string just provides a voltage reference.


NOW:

That IRF830 current limiter in the main 410 volt supply * IS * a real eye
opener !

Goes where no thermionic rectifier tube has gone before.

He he, I know.
Was just pulling Eeyore's trousers but it seems you share the same. Do
you have the right leg and Eeyore the left, or is it the reverse?
Must be pretty uncomfortable.
