What are these parts
I got a pair of custom amp that my uncle built. I am trying to figure out what the outputs are but have not been able to figure it out what they are. They are TO-3 case. They have printing and p/n that look like this.
there are four of each per channel. Does anyone know what they are and what can be used as replacement? I have tried to crossreference them but can find nothing.
any help appreciated,
