Early SWR California Blonde

[Axtman]

I am looking for an early version of the SWR California Blonde schematic that uses 2SC2837 output transistors.

I am NOT looking for the version that has 2SC3264 output transistors. Thanks.

Thanks!

After a lot of messing around it looks like the California Blonde amp's output board section is similar to Workingman 12 output board section. I still would like to see a real schematic for it.

SWR used common designs and cut and pasted them together for various models. SOme schematics in the notes section would even say Rxxx is 10k in this model and 15k in that model, or Qxxx is thus and so.

Early version SWR amplifiers generally have similar schematics.
At the output stage, the difference is mainly in the circuits for adjusting the quiet current.
When servicing great assistance you can use any early SWR schematics.
You can be sure of this, if compare your SWR California Blonde (early) amp, with some of the early SWR schematics.
