Am getting ready to do this build & have a few questions about some of the components. Below is my shot at the Bill of Materials (taken from RobRob's site and augmented with some items not explicitly listed by him). The list does not have a few things loke wire and standoffs. Questions are: 1. Resistors & Capacitors- is it very important to use a specific type of resistor or capacitor (beyond the basic specs) for specific roles ? If yes which ones are critical in that regard ? 2. Chassis - What is a reasonable size assuming I am going to use a tube rectifier and a turret board ? Would 10"x6"x2" (Hammond has this chassis size) be big enough w/o making it really awkward to position the pots and switches reasonably ? Any other observations on the list below greatly appreciated. Thanks. Patrick.
