[Amps] SB-200 input.

[Tom Osborne]

Hi All

I was reading an article in an older QST about doing a conversion on a 
SB-200.

One of the things they did was take the tuned input out and put in a 4:1 
toroid on the input, as the input impedance of the 572B's is around 200 
ohms.  The article said the SWR was around 1.5:1 with this setup.

Is this a good thing to do?  Sure would save a lot of fiddling around 
tuning the input.  73
