I do have the factory manual for the set that comes with full alignment instructions, so we're good on that aspect.
As for actually needing to do one.. while it works, and I suppose I could live without doing the alignment, there are some issues like sound carryover and a few video blips that indicate some bleeding.
I'll post pics in my restoration thread later today and per your warning get a second opinion on whether alignment is necessary though. I don't mind fiddling with things like this and if it takes some practice to get it right... that's what it takes
My main aversion too is that most of this gear is a boat-anchor and you pay almost as much for shipping as for the gear itself.
