Verellen Octal

Even if that device is NOT a tube?


The market says the opposite..... I still enjoy playing my SVT 7 pro even if I own an SVT 2.

Of course, you do what you want.

As for the device being a tube sub/option that makes the future of valve based designs a bit more plausible yeah I have no problems with that.
And you can still use tubes too.

We already know what the market says, and its not always what everyone wants.
More options is better.
 
In what amp do you plan on using them?
First I want to check them in my self built Hiwatt DR405-Clone, 650V anode voltage.

If it works, I'll try them in the 6x KT120 valve amp I built. It has several voltage detays from approx. 600 to 820V anode voltage. I'm curious which power I can reach at 600-700V.

The KT120 are correct biased without a signal at 820V, at full power 500W 750V. But that will be too much for the Verellen.

Please, keep us informed!!

for what it's worth their datasheet specs 700V maximum

 
The market is actually what people want. If class D amp is now replacing class AB everywhere it's for a reason. That's what the market, so the people, wants.
I'm not sure any bass player ever really wanted a class D amp? 20th century bass players probably never gave it a second thought. They would've liked a lighter weight amp, and the first lightweight heads, such as the Markbass Little Mark 2 were class AB with switch mode power supplies. Class D was the next logical step in efficiency and weight reduction. There has been an evolution of class D bringing it to the performance levels bass players enjoy today. Class A, AB, G, D is pretty much irrelevant if it sounds good and suits your needs.

The vast majority of the market has clearly and unambiguously accepted switchmode + class D, those who were offering the legacy lead sled models saw their sales slip to almost zero. Class D represents over 90% of the bass amp market (other than little practice amps).

I've ridden both the solid state lead sled era through the SMPS/class D era with my designs, and when players vote with their wallets and class D wins, it is what it is. Either evolve or get out of the way.

Yes they do. Wight is the main reason. Also, many makers have switched to class D. GK don't even provide support for their legacy class AB stuff and have switched to class D only. Other brands have done the same for the reasons mentioned above.
I don't think there are any reasons to use class AB amps except for tube amps maybe.

Most are being mass produced in places where labor cost are less of a factor and possibly a class D amp is the cheapest to make?

When all that is available is Class D this will of course be the market leader.

Personally I appreciate Verellens effort to keep some variety alive in a sea of sameness.

Apologies, you misinterpreted the point I was trying to make, poorly it seems. I have evolved and am completely in favour of class D, fully appreciating it is the future for most of us for very good reasons.

The point I was trying to make was that bass players primarily wanted something that sounded good; the topology wasn't necessarily a major concern. As lighter, more efficient designs crossed over into bass guitar amps and consigned the majority of heavyweight amps to history, we all benefited both physically and economically. You only have to look inside a class D head to appreciate the drastic reduction of materials consumed compared with an old lead sled.

One thing I would like to reiterate though, is that class AB doesn't have to be heavyweight; I have a stack of class AB amplifiers that each weigh around 3kg.
