RGN4004 Telefunken, big globe, black mesh from 1934, tests NOS+, x-rare
Out of stock
This is a super nice Telefunken RGN4004 with big globe envelope and black mesh that may have seen minor use if at all. It tests with 125/125 mA with 120mA being the 100% value. So, strong and balanced!
Seriously rare item in this condition!
Production code on the bottom is “ei” = February 1934
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.
