A peer review was held on the subject. Following were present:

A. vonHalle
T. Stevenson
G. Rossi
J. Edwards
K. Gilton
S. Ramakrishnan

Guy Rossi explained the changes proposed.
The attached document was discussed. The review was successful. Following
course of action will be taken.

1. Adopt Option 1 ouitlined in the atachment and test as prototype.
2. If the prototype is successful, then Option 3 will be adopted except
that the resistors used will be 200, 1kOhms . This is to reduce the
inductance of the chain.
3. It was decided to procure 5% resistors since the material is same for
both the 1% and 5% units. The 5% resistors are about 30% cheaper.
4. Guy Rossi will arrange to procure 100, 500 ohm resistors (Dale NHL175-07Z)
The resistors are expected to be received within 6 weeks.
5. Two mounting options were discussed. It was decided to try the square
assemply with the resistors mounted horizontally.
