Any Thoughts on the Sonic Frontiers power 1?

I used to run the Von Gaylord LAD-L2 preamp into the power 2 and regret having sold that combo every day since then.....

I rolled the input tubes with NOS and the power tubes were KT88s

pure bliss - I'm about to cry tears of regret

1. Did the SF Power 1 come in a SE version?
If so could anyone elaborate on the differences compared to std Power 1?
2. Can the SF Power 1 be upgraded to the SE by Parts Connexion?
3. Can the the Power 1 be warmed up a bit with some judicious mods or parts replacement, such as caps?

It does come in SE version, but similar to Power 2/3 SE, majority of difference is in power tube per Chris Johnson himself. I never had Power 1 to compare to the SE which I current have, but I did have Power 2 and Power 2SE back to back and I honestly did not hear a big difference. Maybe slightly better bass and extension, but not in midrange warmth if my memory served me right.

From my Line 3SE+ experience, PCX mod will improve transparency, bass definition, top end extension and detail, and midrange texture. It won't warm up the sound by much, if that's what you are after I think it's easier to get there with a different amp.

Semi, In your Line 3SE+ try roll some Amperex Holland e88cc SQ and Ediswan CV5065 if you want a more musical, body and warmer sound.

On my Power 3SE+, I found Reissued GL KT88 and Amperex Holland e88cc SQ dramatically improves the sound in all aspects especially in terms of musicality and body.
