Proforma invoice received, cheque sent.
As mentioned in the SC Class A thread, if there is enough interest in getting another group buy of LS313/352, then I'll organise another one. PM me to show interest at this stage.

A quick update, one half of the order is at Mintech, with the other half due in this week. Once they have the second part, they'll be shipping directly to me.

Excellent news.
Regarding yout previous post : A few people may be sitting on the fence, waiting until some more results come in, before deciding whether it is worth the extras expense to upgrade from the SC HA ("Jaycar")

Perhaps some new PSRR boards might be of use in this project....  |

I'm making several offset correctors up for the people wanting SC Class A HA boards, but the idea of having them made 'proper' is nice.
Jon, sizes for the boards are 2"x1", how many do you reckon to break even?

Hi, another quick update.
The LS313 are only available in TO-78 casing, so these are on the way.
Only difference is the size of the case, and is how the ones I have were supplied.

The LS devices have just been handed to me!  I'll start posting out to those of you whose addresses I have, but I will contact you to confirm details otherwise. Those of you who have had SC Class A pcbs from me, I'll be shipping at the end of the week, just a few more boards to do. |

Great news. I am looking forward to revisiting metal can vs. plastic in this amp. It would be nice if they had a similar advantage as the metal can vs. plastic LM4562 ?

Yes, that'd be quite interesting, thinking back to the differences that were found with the metal can variant.
I think yourself and Leo will be best placed initially to comment as I built mine straight away with the LS devices.
I really, really need to get my amp cased up.

Interestingly, my very original SC 15W Class A used dual metal can devices (LM3811A) in the front end. However, the circuit was further refined, with plastic devices used in the next version, so I can't say which sounded better originally .
