Phase Linear 400 Amplifier

Description

I have been working on Phase Linears for 40 years (and still am!).  Some of my early experience came from talking with Bob Carver when he worked at Phase Linear in Washington long ago.  I learned the tricks to making sure these amps did NOT become a "Flames Linear"!
I have renovated the whole amp and it is working perfectly.   All output transistors are original PL909's and have been matched within 10% per bank. Drivers are new original RCA410's.
Both meters work and lamps are good.
I have put this on my scope and it surpasses factory specs equally on both channels. The DC offset is within limits (Q1 & 2 transistors control it) and the bias has been set for approximately 320mv.  It will be double boxed for safe transport.  Please feel free to ask any questions.
