I think he means heatsinks as 'plancha' seems to mean a grill.
I intend using 200mm with 40mm fins (includes 9mm back- plate. Fins are well tapered and corrugated. What do you suggest is a safe minimum height. (I have 200mm each available, but can cut down. The box will be from 7mm alloy panels)

Thanks for the review. I don't know for VSSA, but i have similar experiences with most fast Current feedback amps.Time for glossy magazine style review.
In fact, you listen what is on the source. And only that.
It can deserve some bad recordings, comparing with nice colored amps, like tubes, can be too harsh, comparing to slow and smooth amps, too smooth, comparing to harsh amps.
But you will find the behavior of the amp to change drastically from one record to an other.
With the stability margin of this amp, its bandwitch, slewrate, distortion...health and simplicity, i believe VSSA diyers will forget their amp for 10+ years
Unless they want to dig the 0.001% subtle remaining on some components behaviors, (Caps, feedback resistances, power supply etc...)
...And begin to ask themselves questions about their sources and speakers
May-i insist only on one point ? With SMPS, take great care to shield carefully the smps from the analog parts (amp and wiring).

Hi Lazy Cat,
a closer sight on the first pic shows this.
Yeees my lucky little pigs, love them
I already had "speaker envy" , but b/f VSSA it was stil manageable... now it has been escalated to the "problem" category......And begin to ask themselves questions about their sources and speakers
Both sides' calibration are done. With current setting, is it safe to connect to 4Ohm speakers?

An externally hosted image should be here but it was not working when we last tested it.

Yes, quite. There is a reason why I almost never use words like "soundstage" ...And the bigger problem will still remain : the ROOM !
Double die 16 A/250 W laterals just arrived, also ready for the next project.
Shitttttt an another thing to follow.....

Did you get p-channel fets also? I have 8 n and 8 p for almost a year now, but besides building dac and your VSSA didn't have time for anything else.
BTW, still waiting Nichicons to arive. I had to go thru forwarder. Courier delivery from Mouser to Serbia is whooping 120$.

VSSA GB - members still to be delivered
Hi VSSA GB members
It looks that all GB members from June's delivery received their VSSA PCB set packages, since I don't have any requests-replies for undelivered shipments on the present day.
Still there are six GB members waiting for their VSSA PCB set deliveries:
BYRTT 8 PCB set
CaféNoir 6 PCB set
ColinAlex 8 PCB set
DavorXXL 6 PCB set
DuffyDawg 4 PCB set + 4 SMPS400
electromf 4 PCB set
These VSSA PCB sets will be send out in the first week of August, immediately when ALF mosfets will arrive here. All material is already packed in sealed envelopes, only ALF mosfets to be added and packages will be send out.
Thanks to all upper GB members to be so patient, you are all true gentlemen.

Yes I have P channel too.
How does this case (SQ) compare to the other cases you filled earlier?
This VSSA official case is made out of the best Aluminum material possibly find around here because of the final brushing finish. All plates are fine brushed so the material needs to be very homogeneous. Plates thickness is 5 mm, they're pre-drilled with threads where needed and the case is adjusted to zero gap, plates tightly touches each other.
Regarding SQ (sound quality) I can tell that it is much better than my demo wooden "case" since the grounding is perfect so the lowest level signals are not lost in any kind of noise. No interferences from outside, all Aluminium material meaning no amplified magnetic fields formed in plate material.
