Summary:
+5 DC increases to evocation
+2 extra Int in Capstone
+10 +15 +15 +20 = 60 electric spell power
+17 universal spell power (new tree has +27, old had +10)
Let me preface this that I have not visited Lamannia yet, going off release notes and ddowiki description of live Arcanotechnician enhs. But here's some feedback anyway.
1) We get a bunch of spell power, but why not add a bit of extra spell crit chance or spell crit damage (instead?).
2) Spell Critical line gives only +1% to a restricted number of damage types. Either make it simply universal +1%, or consider bumping it to 1/1/2/2 or more. Compare to other newer trees.
3) Imbue Defender (T2) seems stronger than Arcane Engine (T4)
Imbue Defender gives bonuses to dog and spell power
Arcane Engine gives only spell power, but has same cost and is higher tier? Perhaps move one of the Evo focus here. Or make dog radiate aura that gives all nearby casters some bonuses.
4) Consider removing the prerequisites also from the SLA line. Or just remove Static Shock. Or replace with something else. Repair Light Wounds SLA, False Life SLA, ...
5) Add Lightning Bolt to the epic feat Master of Artifice; or replace Static Shock with it. Or merge the feat with Master of Air.
6) Shocking Vulnerability: Each Electric spell you cast has a 5% chance of applying 1/1d2/1d3 stack[s] of Vulnerable
This enhancement has very low chance of making mobs vulnerable. Consider bumping the chance to... 100%?
7) Automated Repairs: According to the wiki there is some discrepancy between how often the repairing applies and the description.

8) Palliative Admixture, Critical Admixture - Allow to target self. IIRC the admixture spells have better targeting options than the SLA. Please fix.
9) Critical Admixture heals less damage than advertised in the description. Also description mentions it being affected by Artificer Knowledge Potions but it does not.

10) Consider reducing the AP cost of some Tier 5 abilities (if you haven't already).
