For $5 thought it was worth the risk. Some sort of audio passive filtering tests? |
| alm:
The top and probably bottom unit in the first picture have an output W+F meter. My guess is that this stands for wow and flutter meter, which was a meter commonly used when servicing analog tape systems. |
| RichardM:
Thanks for the reply. I ran a signal through and the cut-off filtering still works. May be some parts worth salvaging. Those glass capacitors look interesting and measure amazingly on my lcr meter across the range of frequencies. They may work well in other audio projects. I will do some reading and also try to work out how to categorise those output transformers when they have no markings etc. Richard |

The "glass capacitors" are not glass but polystyrene film. eg https://docs.rs-online.com/03b5/0900766b8157e132.pdf Not so common now but I routinely was using them in the 1970s. Our component stores also had various sizes of those coil assemblies for making your own coils and transformers. I think they were Mullard branded. Part of the Philips group. |
