Two 6B4G, one Ken-Rad JAN CKR and one Raytheon
See similar listings
These two 6B4G 's are from my 95-year-old father's collection and have his notes written on them. I tested these last week with a Heathkit TT-1 and found that they both tested at 2500 micromohs. My dad was a Korean War veteran who was an engineer and audiophile who made his own amps and speakers. All his gear has been meticulously maintained.
