RGN2004 Telefunken, big globe, black mesh from 1937, tests NOS+, x-rare
Out of stock
This is a super nice Telefunken RGN2004 with big globe envelope and black mesh that may have seen minor use if at all. It tests with 143/146 mA with 116mA being the 100% value. So, super strong and balanced!
Seriously rare item in this condition!
Production code on the bottom is “ia” = July 1937
The tube shows minor shelf wear but is otherwise in great condition for an 80+ years old item.
This rectifier is tested and guaranteed to be in perfect working condition.
