Mercury Tube Test Adapter, Ad-4 To Check Compactrons, Nuvistors, Etc

US $220

  • Upland, California, United States
  • Jun 20th
This auction is for a Mercury Tube Test Adapter, AD-4. This came out when the first 9 and 12 pin Compactrons came out. I don't believe that this will check sweep tubes since the heater pin outs are different than the first Compactron type tubes were introduced. The cosmetic condition is good except for some paint that's missing next to the 12 pin socket. You can see the instruction pages here:       ftp://ftp.flippers.com/TTL/TestEquipment/MercuryAD401.pdf I'll include a copy. Shipping will be for 2 lbs. via  USPS Priority Mail.  I'll ship overseas (inc HI and AK) via First Class Mail  International. California residents must add sales tax (8%).
