Part list

There are several suppliers all over the world, for passive components: Mouser, RS-components, Farnell, Digi-Key, … but only one “Area 51” @ for mylar, saran and elvamide/calaton.

My short list (last column on the right)

For EHT power supply, there is an option using neon bulbs. Recommended components are (2 of them per board):

  • VCC A1A
  • ECQ-E2104KB3
  • VR37000001005JR500

You can consider as well this fuse if using IEC power plug: LittleFuse 0217.032MXP.

You can get most resistors by Vishay, at Mouser or Digi-Key. Particular attention is required for resistors used in audio input transformer. Official service manual says “Erie type 8” (carbon,1kV,1/2W@70°,1W@40°) while OTA says that voltage matters, not so much power handling. Thus, VR37 kind is a minimum, while VR68 is recommended (1W vs 1/2W, and adequate shape):

Screws for grilles:

3×16 is enough but sometimes it fails. 3.5×16 is then required.

3×12 is for the under part.

Screws for grilles: 3×16, 3.5×16, 3×12
