Yes, everything that you mention - Supra tranny, filtration, Black Gates, stepped attenuator, Solen power cap... it does NOT say SE on the front, but as you say, I don't think any of them do. Mikhail sold it to me (on the phone) as an SE, and said these were his recommended options for the model. The only thing I didn't get, and wish I got, was a Neutrik locking jack, just 'cause I think they look cool.
Let us know if you find anything else out about the SLAM SE models without voltage switch, Glod... it seems odd to me that Mikhail would still be making them after he told me (and apparently markmaxx) that we didn't need them...
There is no doubt in my mind you have a SE - and so does markmaxx as well, I think we can conclude. I think the MPX3 SLAM SE has to be seen as a package. It's novelty is based on the adaptation to 6BL7GT/6BX7GT tubes like PFKMan23 also concludes in post #105, but the very SE label only makes sense if the amp has a majority of the options mentioned.
Most Singlepower amps are in one or many ways unique. The sonic differences are probably relatively small, but the fact remains: they are tailored products, why the relevance of discrete model names can be criticized. Perhaps it would be better if every Singlepower amp got a personal name, just like the Stradivarius made instruments.
Still, it is desirably to seek a categorization of the many SP amplifier versions next to the pure base models on the their site. That was the original reason behind this thread. In hindsight, one could then, actually, call Earl's Supra 392
a Supra (SLAM) SE
If more Supras with raised plate voltages are ordered, one might suggest Earl to start calling his beloved Supra 392 just that.
The suggestion wins more reason when one sees that a Singlepower MPX3 SLAM SE, awfully a lot, looks like a Supra with different plate voltage and smaller power capacitors.
And, if the voltage switch is not necessary for the SE label...
About that Neutrik locking jack. I have it too but I am not sure of the benefits. Perhaps it is better isolated than a classic one. I don't really have any use for the very locking feature. I actually find it slightly awkward.
