L'Amp: A simple SIT Amp - Page 93

@Anchan

1. ~8dB

2. 12W = ~14Vpk, (8dB ~2.5X)

3. The CCS FET is dissipating 1.6A X 16V = ~25W, so to keep the temp at 25C above ambient, you'll need a 1.0C/W heatsink or better. The SIT is dissipating 30W, and I suggest a much more generous sink for the SIT. .5C/W is good.

4. I agree, heresy.

Have fun

o.k. Zen Mod,

the same procedure as every year..... my Lowther/Tone Tubby open baffle and I tried to get better bass by a Klipsch SW-110 Subwoofer, but the definition of the baffles got worse so ..... maybe I sell him again....

G

I was joking ......... should we continue with that in Pub ?

generg · 03:15 PM

I thought it to be a good idea because people who want to build this lovely amp get a impression for fitting speakers....

I never go to a pub and I do not drink bear......I am a shy guy! Therefore I am doing electronics!

Ive heard the large Zu audio Dominance is it? They are something. Very powerful, live sound. I bet the Pass SIT amps are a good compliment, probably tame the strong mid range.

Btw- got the 2sk82s in the mail today.

. ..and finished Zen 9. This is the amp building version of chain smoking...
