Smile Service Manual or Scheme

Hello there
This post is rather old. Maybe someone is still reading it ...

I have found two of these class A amplifiers @ ebay but they are without the battery units and am trying to bring live to them.
Is someone out there having a scheme and/or service manual so I can rebuild the battery buffers, adjust the bias current etc. before connecting them?

Some advice on converting them from 110 V to 240 V main voltage would also be nice. This may be the easier part I guess once I know the secondary voltage(s) and currents.

Ultimately, I would love to build an original burning amp like the BA-2, but that is too big a task for me right now.
Thanks in advance,
Markus

Nowadays it seems that almost everybody in USA are saying/writing it as: "I should of known", "I should of tried", "I should of been" ....

Check "there/their", "then/than", "grammar/grammer" and "aluminium/aluminum" (although this may be american spelling) etc.

Also annoying: native english speakers not understanding correctly written basic english sentences... It surprises me every time. It seems we get educated in a language native speakers don't fully comprehend

An example of how little dutch kids are taught english:
