THANKS to all who responded to my plea for help w/ shims on my old
NT-360WB. Ginna Miner at Acorn FAXed me the drawings for the supply
(thanks!!). Lots of good comments about shim DACS locking "full-on",
but I took the few DACS out some time ago (I only had Z1-Z4 to begin
with). This is an old analog supply with knobs.

Further work leads me to believe that the RT-Shims have melted down
inside (at least some seem to be shorted). I got lots of advice on who
to call...I think a call to Ben Hamilton, followed by a call to Oxford
are my first two steps from here.

Thanks again to all of the responses. Just like my neighbors helping to
remove tons (literally...tons) of fallen-tree debris at home, our NMR
neighbors are always willing to rush to the aid of a colleague...this is
really cool.

Warmest Regards,

Rich Shoemaker
