[Amps] every db lost re Tubes vs. Solid State

[Charles Harpole]

I think we should also count pieces of incoming db lost by insertion of various devices.

 

I know ever coax joint, every coax switch, and so on costs rcv db.

 

But what does an amp in line take away?  Tubes or SState better or worse?

 

Does an antenna tuner take away any parts of rcv db?

 

Inquiring minds want to know.  thanks, 73
