What Trevor is afraid of while he spews lies and bull**** far and wide
is the loss of income due to other service ppl being enabled to fix ME
amps 
if they had a service manual.

ME service manuals = Trevor Wilson's financial decline.

Not once has TW ever stated Peter Stein should make manuals available to
all.

He's lose, that's why. 

When these two guys are trundled off to the old folks home with
demetentia,
there will be nobody wanting to fix ME, because there are no manuals.

But an average ME amp has a nice case, nice capacitors, and power
tranny.

People can always strip out the whole audio board and protection boards
if they 
can't understand them and start all over again with a new circuit.

Might sound better, depending on how it is done.

ME amps don't need to be dumped.

I have completely re-engineered Phase Linear 700, Quad 405 amps and
others
and replaced all innards with my own boards and circuits.

The results sounded as well as anything from ME.

But such an exercise ain't cheap.

But when repairs mean high expenses paid to the ME 'monopoly'
then other options don't seem too bad.

Not if there were manuals. Then we's all be able to fix a broken ME
when we came across one.

Wilson and Stein are in our way by means of their obstinacy.

DO NOT BUY ME AMPS BEFORE FULL SERVICE INFORMATION BECOMES AVAILABLE.

Patrick Turner.
