This is the final schematic of my Parallel Single Ended 807 monoblock tube amps diy project. Note that we apply no feedback at all.

There is also a modification schematic using the 5687 tube as driver

The OPTs are hand made designs made by a guy who lives in Beograd (Serbia). All OPTs are special orders according my needs and follow exactly the tube characteristics for each design.
