SissySIT R.3

160mV is just arbitrary mid point, on the way to final setting in thermal equilibrium
so, yes, 190mV-ish being goal figure, if you didn't skim off size of heatsink

yadayada, all other conditions must be met - proper thermal interface between output parts and hsink etc

Thanks, and yes I am using the 5U/400mm cabinet so good amount of sinking is available. And I do see that one channel which is ready gets nice hot in my cold winter here within an hour
Will try to finish the other channel too today and will give a listen initially with my bookshelf and later to my main setup with Waynes line stage or my HPA1 clone preamp and Klipsch Forte IIIs.

My dual mono SIT is ready and now playing music on small monitor speakers 👌

Seems like the bias takes a bit of time to settle after power up with some distortion in the music if played immediately after turn on. I realized around 25-30 seconds to stabilize the bias and music plays smoothly.

First impression of this Sissy is

 

[Zen Mod]

there is no bias/Iq to speak of in first 30secs

tnx to that you have opportunity to witness transition from No Class - C Class - B Class - A Class

so, now you have no just amplifier, but also Educational Device

(remember , M2 is doing that too)

Many Sissy owners claim it gets even better after at least 10 hours of operation.

I found this to be the case, personally, even though I know electrical engineers would state otherwise.

Love my SissySIT.

luckily, I'm not an Engineer, least Electrical



more like 50hrs

CineMag’s on the way!

I fired my babysitter…got a nanny fan

^ I've found that model whines in my setup. YMMV.

Parts rolling in…

Progress…now to begin population…thanks ZM

if in doubt regarding appropriate schematic, just buzz

I’ve been reading all posts since 2018…lots of cool info/comments:

just few teasers, not best angle for pic, but clear enough

finally found some brain to arrange with (one of) my winder(s) to have custom chokes for my concoctions


4mH, 0R15Rdc, good for 4A with no sweat

will use that (CLC) instead of usual CRC (R being 0R1/5W)

caps are 33mF

if CRC was good, this one is going to be goodgood

 

[Zen Mod]

Que?

Voltage of Caps?
