Here I`m offering a very rare matched pair of Klangfilm modules in original condition. I don`t know what for they were used but the schematic is very similar to the V72. It uses the same tubes: two pieces of EF804s and the V72 (CTV72/2) output transformer.
An input transformer is not used in this circuit. If the Klangfilm pres will be used for Hifi application it is not needed. For the use as a micpre an input transformer should be added.
The modules come with schematic! The item "Matched Pair Siemens Klangfilm KL-U086 Modules orig condition Convertable to V72" is in sale since Tuesday, July 21, 2020.
