My first Aleph 4 Monoblock :-)

Smithers · 18th January 2004, 09:40 AM

Hello,

may i introduce my Aleph4 Monoblock?

Technical Data:

DC Offset 20mV
45 V= 2x2.25A
Two Seifert heatsinks, each 0.19K/W that leads to DeltaT=24K.
I used a 450VA 2x36V Transformer, with HFA25PB60 Diodes and 4x33mF BC Components Caps.

Now i have to finish the second one :-)

regards,
Elio

Beautiful work Smithers.

How did you manage the lettering? We'll be waiting to hear how they sound as well.
