early 70's concert bass head schem

[Juan Angel]

Here in spain there is no any service for old sunn amps,
and I need schem for the early seventies concert bass head,
my beloved one died and must be alive as soon as posible.
thank you.

I had a '79 concert bass head that died.  I ordered schematics from Fender, see my older posts for the web address.  
The packet they sent included schematics for both older (with distortion knob) and new (without dist., like mine).
I can email you scans if you like but they may not be the best quality.  Let me know if you want them.
