@georgehifi - sorry to say Roger won't be going down that path. He's just a curious guy that does a lot of research. When he heard Curl talk about the 2300's it got the better of his curiosity, especially given their use by the Grateful Dead with the Wall of Sound set up. So he looked into it and thought he would write about some of his thoughts and findings. If Roger was going down the path of building solid state amps, and he has built at least one I know of in the past, I'd be one of the first to hear about it.
How good is the McIntosh MC-2300 vs modern SS amplifiers?
John Curl gave a most informative talk on the Wall Of Sound used by the Gratefful Dead. He had a lot to do with the speaker end of things but had not much to say about the amplifiers which left me curious about them.
I pulled up the following manual and schematic and suggest anyone interested in advanced circuit design of the 1970s have a look .. http://www.tubebooks.org/file_downloads/McIntosh/MC2300.pdf

There is an earlier discussion about autotransformers where some call the autoformer a "band aid" for a poor design and others slurs. However this is a fine amplifier, virtually bullet proof, and used in great numbers by a band known for its incredible sound.
I welcome any comments and questions.
