If anyone would like to share their experiences with Ed Jahns, his 400-PS, or in some way contribute my effort to make known to the world the man who created the most amazing amplifier, please leave me an e-mail as you would have it appear here.  Any pictures will be greatly appreciated.

Rich,

I enjoyed your web site article on the Fender 400-PS, and it brought back some
recollections for me.

I "met" Ed Jahns by phone in 1978 when I worked the repair shop for a music
store in Charleston WV.  I immediately came to appreciate the designs,
construction, and customer support of Fender [CBS] Musical Instruments.  Our rep
had given me the super-secret instructions on calling for Fender Tech Support.
First, you placed a person-to-person call to Joyce Patterson, who was always in
a meeting or unavailable.  Now Joyce was a real person, but she would never
return the call.  Instead, a tech would call back on their WATS-out line and
presto - toll-free support!

Over the 2 years at the store, I talked with Ed on various troubleshooting
problems, ECOs, and some custom work I was asked to do.  I probably touched some
aspect of every tub amp that ever had the Fender logo.  There was something
educational in every conversation.  I learned - across several occasions - why
(and how) Ed had redesigned the 6L6 tube for the Twin, what causes scratchy
level controls, why a 7025 and a 12AX7A are NOT the same tube, and a number of
other great tips.  He and I both marveled at how the best efforts of circuit
designers to build true, clean amplification were being hammered by the
Marshalls and the Mesa Boogies of the time.  Effects makers were having the
darnedest time getting the Fenders to overdrive an amplifier stage.

Thanks for a great writeup on the 400.

BTW, I enjoyed this article on Harold Rhodes

These two should also be considered among the greats of Rock & Roll !!
