Hopefully all VSSA PCB orders remains active after this intervention.

Of course. Nothing can beat your authentic design and approach.

Great going LC.

The plan is in progress...thank you for your quick reply...
I really agree. Just stick to the design on the part that is hard to get is probably discourage the builders. Another issue might be serviceability, even if we can find the part for the first build, because of unforeseen issues if this part fails people don't know what to do with this board. If its not too hard, just adding the option 2sk/2sj parts encourage more people of jump in.

I dissagree here, the same can be said for an amp having LME49830 voltage driver, exotic part hardly replacable when service is needed.
Look from another perspective, ALF mosfet is very good for audio purposes, even more than other laterals, which are BTW to be honest also not very easy to find/buy. But here we have, all of us audio fans, great opportunity to order and keep ALFETs on the market. Best thing is, it is purely original part, genuine lateral mosfet made according tight specs, not made in some questionable production lines. So I see this as a good way to support producer to invest and to make fine parts for us in the future.

Include a couple of spares in the kit no matter if it bumps up the price. Its an amp and few amps will inevitably blow at a point and should be serviceable. Its what I would have done in that case.

I can speak in favor of the alfet laterals, they are superb mosfets and I think the dual part is very interesting. I have a headphone amp planned with it. as mentioned, just buy a spare or 2. these devices are actually very rugged as well.

tghat being said, while its a good idea to support the ALFET parts, you would simply be ensuring that these particular parts are continued including linear audio parts in general (as opposed to switching). but SEMELAB is pretty unlikely to ever go out of business, bloody huge company

Only difference here is you cannot replace/substitute LME49830 with any other part, but here we can atleast substitute ALF with 2sk/2sj probably with a bit of compromise in performance.

honestly, why must so many people resist SMD? its easier to build, easier to rework, easier to make your own PCBs and higher performance.

whats not to like?

Fear of the unknown for builders who have never tried.
