Bass guitar preamplifier in the Ampeg SVT tradition

Bill of materials
This listing of the components in the project is nearly complete, but it hasn't been thoroughly checked  However, because I used some parts from my existing stock, some components may not have a source listed.

Some notes:
RN60D metal film resistors are military spec parts rated at 1/4 watt, and are equivalent to a 1/2 watt commercial rating
None of the film capacitors requires more than a 400V rating.  In many cases, I used a 630V rated part because that was what was readily available.

Looks like the parts cost is approaching $500 USD, not including tax and shipping.
