Hmm..Lars

Sorry to break the news to you, but also in this case size does matter

Yep, this one is also nice and big and consumes lots of fuel:

Lars,

The height and depth was dictated by the heatsink size. The width is standard 19" rack mount. The size of the heat sink should give me better than 0.3c/watt so I can keep the FETS cool.

Yes but i have to make a big heatsink for my Single End Class A FET's, because it gives the best sound... WRONG

Sorry guys .... There are better ways............!

Less Idle (Waste) power
More audio power 290 Watts RMS in 8 Ohms (> 1 kW in 2 OHMS)
Smaller power supply
MUCH smaller amplifier footprint (credit card size)
NO heatsink
Better sound!!!!!!!!!

Get modern!

Not to be unpleasent or anything, but this is the passlabs forum, the thread is named Zen IV progress report....and furthermore there are pics that clearly states that this is class A amps in question.

Now what makes you think anybody here are interested in digi amps?

Post in the digi forum, plenty of people there who may share your point of wiev.

Magura: sorry but merely trying to pass the message that today it's really not worth while to build a class A amp, as digi amps are both smaller, cheaper and sound better.

So why waste your time, space and money building a Class A amp?

The reasons are plenty, but not to be discussed here. Start a new thread if you think you can back up that statement.

Magura: if you had heard the latest editions of digi amps like ZAPpulse, you would never bother building or discussing a Class A amp. But obviously you haven't. So ..............
