Default Aleph 30

My Aleph 30 Amplifier is finished.

Elkos BHC Aerovox 63V 15000F per channel 6 pieces, bridged with Roedestein 8900pF and Styroflex 2700pF
Trafos prim.18V sec.25V, 400VA.
DC voltage at the exits l=39mV, r=4mV.

UR11 = 5,3V
UQ5 = 4,8V
UQ4 = 4,8V

UR34 = 0,437V
UR35 = 0,493V
UR36 = 0,476V
UR37 = 0,458V
UR38 = 0,465V
UR39 = 0,486V

Panasonic FC 220F Elkos, 10pFGlimmer, Resistors fromWelwyn. Point to point wired directly.

MosFet PCB from Kristijan, normaly for Aleph 2. I separated the PCB and had so constant current and Gain DEVICE in one PCB .

The Amp. becomes very hot, with 3 per channel, about 60C in the middle of the heat sink. May be I will change R19, to reduce the amperes, hoping it will not affect the sound.

The sound is very very good. My Aleph 2 is stronger and has somewhat more strength in the bass foundation, this Aleph 30 has more warmth within in the middle and the high range, somehow somewhat magic, charmful.

Here are some pictures.

Hello Mad_K

very good eyes! yes its a Zapsolute. The Zap has a little bit more drive and detailled bass, more foreward, more killer instinct.
But sometmes i need this kind of sound. Please understand me right, the Solute is in my opinion one of the best too.
