Default So, this is my Quad ZV9!

So, this my Quad ZV9!
I would like to present this apparatus, which I started preparing on 2006 summers yet, to you.
Although, maybe, I would have had a more important thing than this.
Now already anyway it doesn't matter.
That's it.
This worked already then, but I managed to reach away it recently with this in order for something to receive a form only.

Default Holes

Yes, my dear. You know, his name is his flavour!
Because of that my dear Fotios my friend in a way more professional at me.
There are a little on its bottom otherwise.
But this only was a test drilling yet.
I produced very many slivers so whatever.

But I have to produce lunch again now.

some measurement: (Thank you, Teuvo, and of course Pascal!)
CH1 divided by ten, CH2 is input.
Load approximately 8.9 ohms, resistive.
Let us not forget that it turn the phase with 180 degres.
We imagine it meanwhile, what the sky may be like on the planet of a star in a globular cluster. Absolute

You may ask it, why I pack into a box four amplifiers, onto which may respond it: Why not?
But it also, because this works in balanced.
And because I wait for the active crossover very much.
And anyway a unrepentant bloke I am.

That's a nice looking amplifier you've built there, neat construction (I noticed the neatly bent wires around the trafo's) and solid chasis.

Thank you, dear Bigun!

You know, I try to give it an uniform "family form" to my NP amplifiers.
Will be (it is concerned already) with a similar construction F4, with four pieces of amplifiers.
And it is good working since the approximately 10 years my Aleph.
My good old-new Aleph
You may see the "family members", each other on the next picture sitting in his neck:

It looks like you use multiple smaller heatsinks in both amps. Do you have pictures of how you join all of these sinks together, and any tips for getting the best heat transfer amoung all the heatsinks. I will be doing this with my Aleph 30 amp also.

Thank you,

Steve
