SUNN Sonaro Head

[bessee]

I just got a SUNN Sonaro head with a 215 cabinet. In looking through all the archives I can find I only see reference to the Sonaro Combo Amps rather than the Sonaro stand alone head.

Does anybody have any idea;
1.) what the proper tube set was for this amp?
2.) where the serial number and inspection sticker may be?
3.) what vintage this head might be? I'm guessing 1969...???

schematic says 1967 so that is a rough guide.

tube line up is 12ax7, 7199, EL34, GZ34

I don't know much about Sunn, some manufactures changed designs alot between the years under the same name. It might be significant or not but at least this is a rough idea.

There is also some other information and a chassis photo of the Sonaro. might want to compare what you have to that. sorry I couldn't give a more comprehensive answer. Good luck.
