Default Push Pull ain't that bad

Here's the latest snazzy little number with maybe 4watts per channel wih a fair wind and a sunny day.

As a spin off from SEX amp, it was not long before someone tried (successfully) to use 6DN7 (actually 6FJ7 here) in push pull mode. Input/splitter transformer driver triode cap coupled to output triode to output transformers (that are dead weedy)

The PSU is unpluggable as I want to use it for other little projects (6DN7PSE!) and bingo! It sounds very good and I'd love (much) better specc'd 8K output transformers.

Well the picture was too dark and I don't know how to lighten it, so I did this instead - improves the top end!

Hope the amp survived the Dalek attack.
