Anybody out there have a schematic for a Solos II amp? I just bought a Solos II chassis that needs some repair and need the schematic.
I guess that in the 70's the Solos could be purchased in either a 2 x 12 or a 1 x 15 configuration. I don't know if I should build it into a combo amp with a 15" JBL speaker that I have, or if I should build it into a piggy-back head. Any ideas or suggestions?

Personally, I'd say go with a head. I've always found the head/cabinet combination more flexible than a combo.

Here is the schematic and board layouts.

Thank you very much for the schematics and layout sheets. They will definately help a great deal.
Received the Solos II chassis earlier this week. It' looks really clean..no rust or dirt anywhere. One snafu that I haden't counted on is that the power transformer is mounted on the bottom of the chassis, which may shoot my plans to make it into a piggyback head like the Sunn tube amps. My electronics tech hasn't seen the chassis yet, but said that it might be possible to move the "T" to a location inside the chassis. If not, he said that he may be able to figure out a wy to mount the "T" inside the head off of the chassis. If thatcan't be done, I'll have to go to plan #2 - which is building the head with a top mount chassis like a Fender Dual Showman, Bassman, etc.
Again, thank for the schematics.

Did you get your Solos II fixed?
Does your cabinet have casters on it? I am trying to find replacements but the one I just got does not have any .
Trying to replace the handle too but having tough time matching lengths
Thanks
