The LDG tuners are L type rather than pi type which makes them less than 
optimum for that task. I think that 's why they discontinued their amp 
tuner.

I bought the amp chip and the AT-100 tuner from W4RT Electronics and 
installed it in my YC156 amp which is yet to see rf in or out, as it is 
waiting for a new house and consequently, the new shack to be built.

Guess I'll see how it goes in around 12 or 14 months time, when I have 
hopefully moved in.

73,
Shackless Alek.
