This amp will look quite familiar as it is an updated version to my old prologue amp using the same tube set-up. The main difference is that I am using a choke load on the 5842 driver instead of the original RC load which allowed me to share the same B+ supply with the 1626 output tube. The purpose of this amp is to eventually power my tweeters once I get my 3-way horn system up and running. The RC filter between the driver and output tubes will be used to get a high-pass filter around 1kHz in my case; you could use a regular 100nF/250K combination to keep it full-range. I may even end up adding the complete HP filter in here and remove the passive XO components speaker-side.
