Need Flat Beryllium Copper Fingerstock for RF Tube Socket Repair

Hello DigiKey Community,

I need help selecting the correct beryllium copper fingerstock for repairing a 3CX3000A7 RF tube socket in an Elenos T5000 FM transmitter.

Application Details:

  • Repair grid ring contacts on cylindrical tube socket

  • The fingerstock will be formed into a circular ring (~12-15" circumference)

  • Will be silver soldered to the socket base

  • Must be flat strip design (not clip-on, hook-on, or edge mount)

  • NO PSA adhesive backing

Material Requirements:

  • Beryllium Copper

  • Unplated or Tin plated (suitable for soldering)

  • Length: 16-24 inches

  • Operating temperature: RF transmitter environment

Products I’ve reviewed but aren’t suitable:

  1. 81-02-14274-2000 (Parker Chomerics) - Has PSA adhesive backing

  2. 182RF9C070L-24-02 (Tech-Etch) - Clip-on style, difficult to form into ring

What I’m looking for:

  • Flat strip “grounding contact” or “special mount” style

  • Designed to be soldered/welded

  • Can be easily formed into circular shape

  • Similar to Parker Chomerics “Grounding Strips” (Table 39-40) or Tech-Etch “Special Mount” products

Questions:

  1. Which beryllium copper fingerstock products in your catalog are flat strips without mounting clips?

  2. Are there products specifically for soldering/welding applications?

  3. Do you stock any “contact ring” products that are pre-formed?

Any recommendations would be greatly appreciated. I can provide photos of the damaged socket if helpful.
