The Telefunken Spez 801 receiver  has ACH1 as CW/AM-detector and BFO
Spez 801 receiver has ACH1 as detector and BFO
Telefunken Spez801 receiver AGC. It has an extra IF amplifier to feed the AGC-detector,
two time-constants, and some AGC delay (meaning that a certain signal level must be present
before the AGC starts) using the resistors 211-212-212a.
The AGC line is also divided into two legs - as found in Drake TR-4, 2-A, 2-B etc
Note that signal diodes are drawn the wrong direction, it often happened on German circuit
diagrams before 1950, they obviously didn't know which was right, hi!
I enjoy collecting these items and I will show them on my website for others to enjoy. I am not interested in selling them, however - please do not ask.
Instead, I hope to help others who collect this type of gear and would like to hear from them.
