845
SE: Massive two-chassis 25wpc amp built as my first
foray into SE. I wound my first pair of output transformers for this
project. 45 transformer coupled drive, "Super-mu-Follower©"
input stage. A fairly detailed narrative on the output transformer development is
included.

/ 300B
SE: I needed a new 'summer amp' because though I may love the 845, it puts
out in excess of 700W of heat. My previous summer amp (EL34 PP Integrated)
has been put out on permanent loan to a friend. 5842 gain/drive stage with
plate choke. As with the 845SE, I wound
the output transformers.
2A3
Line
Stage: A four channel line stage. The line output channels have a
C-L high pass
filter to remove sub energy while the sub channels are full range, relying on
the sub-woofer low pass filter. The transformer coupled inputs can accept
balanced (XLR) and single ended (RCA) inputs.
