[JMS] Millen amp + exciters on the air

[dennisbrady at juno.com]

I just got the 90881 amp 'restored' and on 20 M  with a pair of T-40's. 

Plate tank and grid coils are B & W plug in units.. The genuine JM coils
are pretty rare and I've never seen any at swap meets, etc.  The mods
to use B&W coils ( aka BC-610 ) are easily reversed with a soldering iron..

The amp performs well and was easily neutralized and is quite tame with 
no parasitics.. I did need to add a shield can over the grid coil to prevent
feedback oscillation on the same band as the coil set...

The pix show the innards with meter shield and 'balancing plate' added
to back of the chassis.. Not really a 'restoration' as much as a functional
repair.. These JM units are my every-day-drivers rather than shelf queens.
I'm a function over form type guy, anyhow...

Included are the pix of the 90880 exciters that cover 80/40/30/20. I have
B&W coils sets for 160 - 10 M.. 

C U this weekend on the SKCC WES 20M with the T-40's..
