Needing information on the foil to ? Anti corrosion mounted transistors

Post by Dougieloo@aol.com » Sun Nov 17, 2019 4:18 pm

I am look for some info on the Transistors that attached to the foils I have measured the OMS AT 25 some of the questions I have a are

1: how many Transistors are there per foil one for foil or two per foil

2: I know that one of the leads attach to the foil bolt but not sure we’re the other side attaches to. Any pictures

Picture of original foil anti-corrosion Transistor
would be great or any information

3: can I use a new style Transistor compared to the old original style transistor picture of the original transistor below

Thank you Mark
So do I attach a wire between the magnesium sacrificial zinc to the ss foil using the 25 OM transistor ??
Another Question would be is there one transistor per foil or two there is two mag. Sacrificial zincs per foil mounted in the magnesium hull and then another 2 sinks of some kind mounted on the the foil it’s self any hint as to the type of sink that is attached to the Ss foil ?
