Re: Impressed
well, according to the dust on the turntable, he might say; what WAF?? ....
but anyway, very nice work

I`m VERY impressed!
How do you manage the WAF?

Fans are Papst 4184 NXH (24 VDC) operated @ 8 VDC. Noise is kept at a minimum while junction temp is abt 50 degrees. Note that I'm using 10 output devices, instead of 12, biased @ >400 mA each.
Mad_K:
Must be >6000, I stopped counting long ago.
jewilson:
Even with high performance heatsinks like the Fischer LA1-10A (approx. 0.2 K/W), it is practically impossible to run both channels of Aleph 1.2 in one chassis.
Transformers are 2.5 KW - 55 A each (45-0-45) and bridge rectifiers are IXYS VBO 50-16 NO7.
Uli:
I've been married for 17 years and WAF was never a problem. I have my own "playroom" in the basement and you know what they say, "the bigger the boys the bigger the toys".
dhfreakie:
Platter surface and arm bearing are always clean, the rest doesn't matter.
Thank you all for your comments,

The other amp is an ML3 clone I built abt 10 years ago and it is used to drive the LF tower.
Preamp is Aleph LOno (Ono + Aleph L) which I built abt 1 year ago.
There is also an extra Ono which I use with the second TT.
Active crossover is tubed 2-way (LP=18db/oct, HP=6db/oct, both xover points variable between 60 and 120 Hz, and LP gain variable between 0db and -12db).
