Default Re: AR88 Low HT

At some point it's probably worth replacing the three 33K screen resistors in the coil box (shown as 33M on the circuit). They go high in value , dropping the front end screen voltages and reducing the sensitivity. Snag is, they're a pig to get at - a good training excercise if you are considering taking up brain surgery!
