wavebourn:
Hi guys,

do you like this layout?

WA1GFZ:
I would move the small tubes back an inch or so. This will allow more room the wire them.

wavebourn:
Thanks, interesting idea!

What if to move phase splitter tubes back one inch leaving indicators on the edge?

WA1GFZ:
I would move the phase splitter tubes back between the input amp and output. This will allow more room to wire each socket.
I don't like stacking components around tube sockets. Too hard to work on. I like all the parts on one plane.

wavebourn:
I will order PCBs for each channel of a phase splitter.

Here is the schemo:

Correction: 6N1P will be loaded on 27K resistors instead of 56K and powered from unregulated 375V, 6N6P will be used instead of 6N1P

Almost all stages are directly coupled for better stability on low frequency end.
